SINAMICS G120: Information on using a 230V switching voltage at the relay outputs DO 0 and DO 2 of the CU230P-2.
What should be considered when using the relay outputs DO 0 and DO 2 of the CU230P-2?
230V AC can be switched using the relay outputs DO 0 and DO 2 of the Control Unit. These terminals can therefore be at 230V AC - independent of the voltages present in the power module.
For this reason, when working at the inverter appropriate protective measures must always be carefully observed.
Cables with double insulation must always be used for control unit relay outputs DO 0 and DO 2 when 230V is connected to these terminals in order to ensure operational safety.
