GEH-6639 ! - FIRE AND EXPLOSION HAZARD / ATTENTION! – RISQUE D’INCENDIES ET D’EXPLOSIONS: ARNING 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.

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.
CS300 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.
GEH-6639 2.4 DESCRIPTION OF CONTROL TERMINALS Terminals Function Voltage, Current Input of the precharge enable control (15 - 35V, 5 - 11mA) Output of the MLP static signal (low - active signal) (5 … 35V, 20mA source) (Common) Ground of the MLP and ML static signals Reference point for Power supply +24V Power supply output +24V (32V / 300mA max)
GEH-6639 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).

GEH-6639 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. 3.1 DIP-SWITCHES AND JUMPER On R-SM3-L card S1.1-4...

CS300 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.
GEH-6639 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.
