Chapter 1 - SAFETY PRECAUTIONS  
NOTE!  
The terms “Inverter”, “Controller” and “Drive” are sometimes used interchangably through-  
out the industry. We will use the term “Drive” in this document  
Les mots “Inverter”, “Controller” et “Drive” sont interchangeables dans le domaine  
industriel. Nous utiliserons dans ce manuel seulement le mot “Drive”.  
WARNING! / ATTENTION!  
According to the EEC standards the CS300 and accessories must be used only after checking that the machine  
has been produced using those safety devices required by the 89/392/EEC set of rules.  
Drive systems cause mechanical motion. It is the responsibility of the user to insure that any such motion does  
not result in an unsafe condition. Factory provided interlocks and operating limits should not be bypassed or  
modified.  
Never open the device or covers while the AC Input power supply is switched on. Minimum time to wait before  
working on the terminals or internal devices is 5 minutes.  
If the front plate has to be removed because the ambient temperature is higher than 40 degrees, the user has to  
ensure that no occasional contact with live parts will occur.  
Always connect the Drive to the protective ground (PE) via the marked connection terminals (PE2) and the  
housing (PE1). Adjustable Frequency Drives and AC Input filters have ground discharge currents greater than  
3.5 mA. EN 50178 specifies that with discharge currents greater than 3.5 mA the protective conductor ground  
connection (PE1) must be fixed type and doubled for redundancy.  
The drive may cause accidental motion in the event of a failure, even if it is disabled, unless it has been discon-  
nected from the AC input feeder.  
Selon les normes EEC, les drives CS300 et leurs accessoires doivent être employés seulement après avoir verifié  
que la machine ait été produit avec les même dispositifs de sécurité demandés par la réglementation 89/392/  
EEC concernant le secteur de l’industrie.  
Les systèmes provoquent des mouvements mécaniques. L’utilisateur est responsable de la sécurité concernant  
les mouvements mécaniques. Les dispositifs de sécurité prévues par l’usine et les limitations operationelles ne  
doivent être dépassés ou modifiés.  
Ne jamais ouvrir l’appareil lorsqu’il est suns tension. Le temps minimum d’attente avant de pouvoir travailler  
sur les bornes ou bien à l’intérieur de l’appareil est 5 minutes.  
Si la plaque frontale doit être enlevée pour un fonctionnement avec la température de l’environnement plus  
haute que 40°C, l’utilisateur doit s’assurer, par des moyens opportuns, qu’aucun contact occasionnel ne puisse  
arriver avec les parties sous tension.  
Effectuer toujours des connexions de terre (PE) par le biais des bornes (PE2) et du chassis (PE1). Le courant de dispersion  
vers la terre est supérieur à 3,5 mA. Selon EN 50178 il faut prévoir dans ces cas une double connexion à terre.  
WARNING! - ELECTRICAL SHOCK AND BURN HAZARD /  
ATTENTION! – DÉCHARGE ÉLECTRIQUE ET RISQUE DE BRÚLURE :  
When using instruments such as oscilloscopes to work on live equipment, the oscilloscope’s chassis should be  
grounded and a differential amplifier input should be used.  
Care should be used in the selection of probes and leads and in the adjustment of the oscilloscope so that  
accurate readings may be made. See instrument manufacturer’s instruction book for proper operation and  
adjustments to the instrument.  
Lors de l’utilisation d’instruments (par example oscilloscope) sur des systémes en marche, le chassis de  
l’oscilloscope doit être relié à la terre et un amplificateur différentiel devrait être utilisé en entrée.  
Les sondes et conducteurs doivent être choissis avec soin pour effectuer les meilleures mesures à l’aide d’un  
oscilloscope. Voir le manuel d’instruction pour une utilisation correcte des instruments.

WARNING! - FIRE AND EXPLOSION HAZARD / ATTENTION! – RISQUE D’INCENDIES ET D’EXPLOSIONS:  
Fires or explosions might result from mounting Drives in hazardous areas such as locations where flammable or  
combustible vapors or dusts are present. Drives should be installed away from hazardous areas, even if used  
with motors suitable for use in these locations.  
L’utilisation des drives dans des zônes à risques (présence de vapeurs ou de poussières inflammables), peut  
provoquer des incendies ou des explosions. Les drives doivent être installés loin des zônes dangeureuses, et  
équipés de moteurs appropriés.  
WARNING! - STRAIN HAZARD:  
Improper lifting practices can cause serious or fatal injury. Lift only with adequate equipment and trained personnel.  
Une élévation inappropriée peut causer des dommages sérieux ou fatals. Il doit être élevé seulement avec des  
moyens appropriés et par du personnel qualifié.  
WARNING! - ELECTRIC SHOCK HAZARD / ATTENTION! - CAS DE DECHARGE ELECTRIQUE:  
-
-
-
Drives and motors must be grounded according to NEC (for USA) and EN 60204 (for Europe).  
Replace all covers before applying power to the Drive. Failure to do so may result in death or serious injury.  
Adjustable frequency drives are electrical apparatus for use in industrial installations. Parts of the Drives are  
at high voltage during operation. The electrical installation and the opening of the device should therefore  
only be carried out by qualified personnel. Improper installation of motors or Drives may therefore cause  
the failure of the device as well as serious injury to persons or material damage. Follow the instructions  
given in this manual and observe the local and national safety regulations applicable.  
-
-
Tous les moteurs et les drives doivent être mis à la terre selon le Code Electrique National ou équivalent.  
Remettre tous les capots avant de mettre sous tension le drive. Des erreurs peuvent provoquer de sérieux  
accidents ou même la mort.  
-
Les drives à fréquence variable sont des dispositifs électriques utilisés dans des installations industriels.  
Une partie des drives sont sous tension pendant l’operation. L’installation électrique et l’ouverture des  
drives devrait être executé uniquement par du personel qualifié. De mauvaises installations de moteurs ou  
de drives peuvent provoquer des dommages materiels ou blesser des personnes.On doit suivir les instruc-  
tions donneés dans ce manuel et observer les régles nationales de sécurité.  
CAUTION! / PRECAUTION!:  
-
-
-
Do not connect power supply voltage that exceeds the standard specification voltage fluctuation permissi-  
ble. If excessive voltage is applied to the Drive, damage to the internal components will result.  
Do not operate the Drive without the ground wire connected. The motor chassis should be grounded to earth  
through a ground lead separate from all other equipment ground leads to prevent noise coupling.  
The grounding connector shall be sized in accordance with the NEC or Canadian Electrical Code. The  
connection shall be made by a UL listed or CSA certified closed-loop terminal connector sized for the wire  
gauge involved. The connector is to be fixed using the crimp tool specified by the connector manufacturer.  
-
-
Do not perform a megger test between the Drive terminals or on the control circuit terminals.  
Because the ambient temperature greatly affects Drive life and reliability, do not install the Drive in any  
location that exceeds the allowable temperature. Leave the ventilation cover attached for temperatures of  
104° F (40° C) or below.  
-
-
-
Be sure to remove the desicant dryer packet(s) when unpacking the Drive. (If not removed these packets  
may become lodged in the fan or air passages and cause the Drive to overheat).  
The Drive must be mounted on a wall that is constructed of heat resistant material. While the Drive is  
operating, the temperature of the Drive's cooling fins can rise to a temperature of 194° F (90°C).  
Do not touch or damage any components when handling the device. Changing of isolation gaps or removing  
the isolation covers is not permissible.

——————— INSTRUCTION MANUAL ————————  
 
CS300  
-
-
Protect the device from disallowed environmental conditions (temperature, humidity, shock etc.)  
The electrical commissioning should only be carried out by qualified personnel, who are also responsible  
for the provision of a suitable ground connection and a protected power supply feeder in accordance with  
the local and national regulations. The motor must be protected against overloads.  
-
-
-
-
-
No dielectric tests should be carried out on parts of the frequency inverter. A suitable measuring instrument  
(internal resistance of at least 10 k/V) should be used for measuring the signal voltages.  
No voltage should be connected to the output of the drive (terminals C, D).  
Ne pas raccorder de tension d’alimentation dépassant la fluctuation de tension permise par les normes.  
Dans le cas d’ une alimentation en tension excessive, des composants internes peuvent être endommagés.  
Ne pas faire fonctionner le drive sans prise de terre. Le chassis du moteur doit être mis à la terre à l’aide  
d’un connecteur de terre separé des autres pour éviter le couplage des perturbations.  
Le connecteur de terre devrait être dimensionné selon la norme NEC ou le Canadian Electrical code. Le  
raccordement devrait être fait par un connecteur certifié et mentionné à boucle fermé par les normes CSA et  
UL et dimensionné pour l’épaisseur du cable correspondant. Le connecteur doit être fixé a l’aide d’un  
instrument de serrage specifié par le producteur du connecteur.  
-
-
Ne pas exécuter un test megger entre les bornes du drive ou entre les bornes du circuit de contrôle.  
Étant donné que la température ambiante influe sur la vie et la fiabilité du drive, on ne devrait pas installer  
le drive dans des places ou la temperature permise est dépassée. Laisser le capot de ventilation en place  
pour températures de 104°F (40°C) ou inférieures.  
-
-
-
Lors du déballage du drive, retirer le sachet déshydraté. (Si celui-ci n’est pas retiré, il empêche la ventila-  
tion et provoque une surchauffe du drive).  
Le drive doit être monté sur un mur construit avec des matériaux résistants à la chaleur. Pendant le fonctionnement  
du drive, la température des ailettes du dissipateur thermique peut arriver à 194°F (90°).  
Manipuler l’appareil de façon à ne pas toucher ou endommager des parties. Il n’est pas permis de changer  
les distances d’isolement ou bien d’enlever des matériaux isolants ou des capots.  
-
Protéger l’appareil contre des effets extérieurs non permis (température, humidité, chocs etc.).  
-
La mise en service électrique doit être effectuée par un personnel qualifié. Ce dernier est responsable de  
l’existence d’une connexion de terre adéquate et d’une protection des câbles d’alimentation selon les pre-  
scriptions locales et nationales. Le moteur doit être protégé contre la surcharge  
-
-
Il ne faut pas éxécuter de tests de rigidité diélectrique sur des parties du convertisseurs. Pour mesurer les  
tensions, des signaux, il faut utiliser des instruments de mesure appropriés (résistance interne minimale 10  
k/V).  
Aucune tension ne doit être appliquée sur la sortie du convertisseur (bornes C, D).

Chapter 2 - COMPONENT IDENTIFICATION AND SPECIFICATION  
2.1 GENERAL DESCRIPTION  
CS300 is a half-controlled three phase AC/DC converter for supplying DC link voltage to a series of AC Drives,  
with C and D terminals parallel connected.  
The precharge of the drive capacitors (time setting set via dip-switches) is done by partializing the mains  
voltage via a thyristors bridge. A diagnostic circuit allows detection of a mains power supply dip for  
system use.  
NOTE!  
The direct parallel connection of the outputs (U2,V2,W2 terminals) of two or more inverters  
is not possible !

2.6 CONVERTER SIZE SELECTION  
Within the specified voltage field, the CS300 converter supplies the same rated direct current independently of  
the voltage itself. The increase of the output voltage causes an increasing in the transferred power, whereas  
inverters are devices with a typically constant transferred power (the supplied current decreases with the increasing  
of the output voltage).  
As for the choice, therefore, the calculation is based on a common unit, the direct current of the intermediate  
circuit, which, as for the inverters, is not mentioned into the product instruction manual and has therefore to be  
calculated. Furthermore, the confrontation between the two foreseen functioning classes has to be homogeneous  
(IEC 146 class 1 and 2).

-
4-pole “standard” motor  
“typical” efficiency for “standard” motors (ηMot  
the “typical” inverter efficiency is considered equal to 0.97 (ηI)  
)
mains power supply voltage 3 x 380V (conservative value if referred to a rated voltage of 3 x 400V)  
there are two value columns referring to a continuous functioning (class 1) or to a functioning during an  
overload phase (class 2) (150% for 60 seconds).  
The current value in column 1 is calculated as  
IDCL = PMot / (hMot x hI x ULN x 1.35)  
where for column „Current Dclink IDCL Overload class 2“ it is obtained multiplying by 1.36.

Chapter 3 - SELECTION OF THE CS300 CONVERTER  
The CS300 converter has to be chosen so that the sum of the inverter DC-link currents, both for class 1 and 2, is  
lower or equal to the corresponding ones stated in chapter 2.6.1.

Selection of the ML signal function  
3.2 USE OF S1 SWITCH  
Relevant only for limited application cases  
If the system functioning allows a limited dip voltage value of the DC-LINK, (a condition obtainable by handling  
the DC-LINK with a suitable software or with additional external capacitors) it is possible, during a mains dip  
with a maximum duration time of 10mS, to prevent the thyristor switching off, of the CS300, during the detection  
of the voltage drop (repeating then the precharging sequence once the voltage is restored).  
The disadvantage of such function is obviously the presence of a high current inside the CS300 once the voltage  
is restored. For this reason it is necessary to take appropriate countermeasures by checking the decreasing slope  
of the DC-LINK voltage during the mains dip. Therefore, knowing the value of the connected capacitors and the  
maximum current supplied by the CS300, it is possible to calculate the maximum “mains dip” bearable by the  
converter itself.  
Example:  
Calculate the maximum “mains dip” bearable by a converter size 185A, whose mains choke has the following  
values: 0.148mH 173 rated A and 350A of saturation current. The converter supplies 8 inverters AV300- 3011  
(the internal capacitors value of each inverter is equal to 470µF); using an oscilloscope, it has been stated that  
during a normal functioning, in case of a mains dip, the DC-LINK discharges 70V after a 3-mS mains dip.  
The aim is to state whether such “mains dip” can be overcome without the precharging phase.  
Considering a series resistance (sum of the capacitor parasite drag and of the connection contact resistances)  
equal to 100mOHM (0.1 OHM), act as following:  
DATA:  
R = 0.1 W  
L = 0.14 mH  
V = 70V  
C = 3760 mF

from which :  
IP = 572.3A  
It is obvious that considering a 70V discharge of the DC-LINK (3-mS mains dip) the current is too high for the  
converter. As a consequence, it is necessary to consider a lower voltage reduction (corresponding to a shorter  
mains dip). Therefore, with a voltage reduction of 35V (1.5-mS mains dip), the new value will be:  
IP= 286.1 A  
Such value meets the needing of both the converter (which for short periods is able to bear a current value two  
times the rated one) and the inductance, whose saturation current is higher than 300A.

1) Set all the switches in off position (18-seconds ramp time), use a current probe able to detect a current  
peak 10mS between the C or D terminal of the DC-LINK.  
2) At this point read the measuring of the maximum peak current present on the DC-LINK during the precharging  
phase.  
3) If the measured peak current is much lower than twice the value of the CS300 rated current, it is possible to  
select the switch for a lower ramp time (SW3.4 - 8- second ramp time). Go back to point 2.  
Such operation will be repeated till the measured peak current is equal or lower than twice the value of the  
converter rated current.

With “CV” jumper mounted (on), the signal available on the terminal 36 will be LOW with AC mains voltage  
lower than the undervoltage threshold (see figure 3). It will be HIGH, with AC mains voltage higher than the  
undervoltage threshold.  
With “CV” jumper open (off), the signal on the terminal 36 will indicate, with an impulse of about 150ms, (low  
level signal) that the power supply voltage has had a transition at a level lower than the undervoltage threshold.

Chapter 4 - CONTROL DESCRIPTION  
4.1 OK RELAY  
The OK relay has a normally open contact which close at the end of the precharging phase if no alarm condition  
is present (overtemperature, power supply on the regulation card +/-15V).  
The contact is closed during the normal functioning of the device and also during an undervoltage situation. The  
contact opens when a failure occurs (see the alarm conditions described above) or when the power supply is  
switched off and the DC-LINK is completely discharged (C and D terminals).  
4.2 PRECHARGE ENABLING CONTROL  
Such input allows to delay the precharging phase with respect to the moment in which the power supply (U,V,W  
terminals) is applied.  
The precharging phase occurs supplying terminals 23 to +24V (available on the terminal strip).  
(common on terminal 52).  
4.3 MLP SIGNAL  
The MLP signal is a digital output available on the terminal 32.  
This signal is a sum of the undervoltage threshold (via S2.1-3 set) and the precharging phase.  
It will be LOW with a 0.5mS delay after the undervoltage threshold is reached. The digital output will be again  
HIGH, at the end of the precharging phase. (This sequence is repeated at every mains dip)  
(see chapter 6.2 figure B).  
4.4 ML SIGNAL  
The ML signal is a digital output available on terminal 36  
It is the AC mains voltage monitoring.  
With “CV” jumper mounted (on), the ML signal will be LOW when the undervoltage threshold is reached.  
The digital output will be HIGH when the voltage is above the threshold (see the above table).  
With “CV” jumper not mounted (off), the ML signal will indicate, with a 150mS pulse, an undervoltage value  
transition.  
When the voltage comes back above the threshold value, this will be not revealed by the ML signal.  
(see chapter 6.2 figure B).
