Electrical installation - motor
Note the following during installation:
Note the correct direction of rotation indicated by the
arrow on the fan cover when connecting the motor.
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).
Only connect the motor to the power supply using a
suitable cable. Information on this can be found in the
motor's terminal box.
Note the technical data for the motor (referring to the
nameplate on the motor).
Provide a separate power supply for the external fan
for motors with external fans (identity code specifica-
tion "R").
Refer to the operating instructions for the pump
and the motor manufacturer's instructions for more
detailed information on the electrical connections.
