Electrical isolation between power terminals, control terminals and housing
– If the terminal X106 is used, e.g. to connect an external PTC thermistor or
a thermal contact, ensure at least one basic insulation to the motor or
mains potential to not restrict the protective separation of the control
terminals.
– The terminal X106 is connected to PE inside the device but cannot be used
for protective earth.
– If terminal X107 is used for connecting a motor holding brake, at least one
basic insulation to the motor or mains potential has to be provided, so
that the protective separation of the control terminals is not limited
Isolation by functional insulation
Isolation by basic insulation
Safe isolation by double or reinforced insulation
Protection against accidental contact is guaranteed without any further measures.
