Even after the CM is disconnected from all the power supplies there still may be hazardous voltage on the CM
connectors. Achievement of safe voltage level is indicated by the extinction of all LEDs on the CM front panel.
This may take up to 15 minutes after the CM is deenergized.

Type of MCB shall be selected according to CM consumption data given in Table 1.
If the CM is connected to DC voltage, pay special attention to the correct polarity for CM_16_1(60_Par2_Par3) .

Connection of CM_16_1 to power supply is shown below.
If Manual generators CBunit_ManGen are used for charging the CM, DC voltage outputs shall be connected to
power supply inputs of CM_16_1. Pay special attention to the correct polarity for CM_16_1(60_Par2_Par3).
Arrangement of output wires of Manual generators CBunit_ManGen_1 and CBunit_ManGen_2:
• red colour wire - positive polarity output wire;
• black colour wire - negative polarity output wire;
• yellow-green clour wire - manual generator earting wire.
