Electrical installation - motor
Note the following during installation:
Use an electrical isolating device in the mains supply
cable, such as a mains switch, to de-energise the
pump independently of the entire installation (e.g. for
repairs).
The metering pump is equipped with a 1-phase wide-
range voltage power unit.
Refer to the operating instructions for the pump
and the motor manufacturer's instructions for more
detailed information on the electrical connections.
