(Pos. b) The sensor, external setpoint and
[aux.]/[ext.off] input cable must be necessarily
screened and must be inserted into the gland M12
or M16. The cable glands of the converter are
adapted to the assembly with a shielding braid (see
below).
• The electric characteristics (frequency, voltage,
nominal current) of the motor-converter are men-
tioned on the pump identification sticker (item 19).
Check that the motor-converter complies with the
mains supply used.
• The electric protection of the motor is integrated
into the converter. The parameters take into
account the characteristics of the pump and must
ensure its protection and the one of the motor.
• In case of impedance between earth and neutral
point, install a protection before motor-converter.
• Provide a fuse-disconnecting switch (type gF) to
protect the mains installation (Fig. 1, 2, item 11).
NOTE: If you have to install a differential circuit-
breaker for users protection, it must have a delay
effect. Adjust it according to the current men-
tioned on the pump identification sticker
(item 19).

7.4 Electrical connections
DANGER! Danger of death!
Inadequate installation and electrical connections
can be life-threatening.
• Electrical connections shall only be made by
approved specialised electricians and in compliance
with the applicable regulations.
• Accident prevention regulations must be observed.
• Do not forget to connect to earth.
CAUTION! Danger of mains overload!
An inadequate mains design can lead to system
failures and can lead to cable fires due to mains
overload.
CAUTION! Danger of material damage!
A connection error would damage the converter.
The power cable shall never touch the pipe or the
pump ; make sure that it is protected against any
humidity.
(Pos. a) The power cable (3 phases + earth) must be
fed through the cable gland M25. Nonallocated
cable glands must remain sealed with the plugs
provided by the manufacturer.
