Using Residual-Current-Operated Circuit Breakers at HMV Supply Units

Due to their function, regenerative HMV0x.1R supply units are unsuitable for
the use of residual-current-operated circuit breakers.

Insulation Monitoring Devices
Insulation monitoring devices are normally used in IT mains with insulated
neutral point. The aim is to have a monitor triggered in the case of ground
fault – which means in the case of error – without having to switch off the
electrical equipment.
When the monitor signals an error, the ground fault is detected and removed
without operation being interrupted. Switch-off only takes place if a second
ground fault occurs before the first one has been removed.
As insulation monitoring devices also measure the ground current at the
mains input of the building, too high leakage current can cause accidental
false triggering.
There are the same notes on application applying as mentioned in the previ‐
