Note
■ The control circuit must be supplied
with power without being able to be
interrupted by the power supply utility.
This means a separate power supply
is required for the control circuit.
■ A separate connection for the control
circuit calls for the internal wiring to be
changed. This may only be carried out
by an electrician according to the wir-
ing diagram.
■ The control circuit power supply and
the cable for the power-OFF signal can
be combined in a single 5-core cable.
