External DC 24 V voltage supply
MOVIDRIVE
®
compact
units have an internal DC 24 V supply with a maximum contin-
uous power of 50 W. The units can be operated without an external DC 24 V voltage
supply. If the inverter’s control electronics are to remain ready for operation when the
power supply is switched off, an external DC 24 V power supply unit with at least 50 W
continuous output power must be connected at VI24. The permitted peak output power
must be at least 100 W for 1 s. This power supply unit then takes over the complete
DC 24 V power supply for MOVIDRIVE
®
compact
. In this case, switch on the external
DC 24 V power supply unit before or at the same time as the mains contactor.
NOTE
SEW-EURODRIVE recommends operating units with fieldbus (MC_41A and
MCH42A) with an external DC 24 V voltage supply.
