(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 (see below).
- (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
mentioned on the pump identification sticker.
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-convert-
er.
• Provide a fuse-disconnecting switch (type gF) to
protect the mains installation.
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.
NOTE: This pump is equipped with a frequency
converter and may not be protected by a resid-
ual-current-operated protection switch.
Frequency converters can impair the function of
residual-current-operated protection circuits.
Exception: Residual-current-operated protection
switches which have a selective universal-cur-
rent-sensitive design are allowed.
• Labelling: RCD
• Trigger current: > 30 mA.
• Use power cables conforming to standards.
• Network protection: maximum acceptable 25 A
• Trigger characteristic of the fuses: B
• You can change the orientation of the motor-
converter by quarter turn when removing the
fixing bolts of the motor and reorientating the
motor to the position wished. Re-screw bolts.

• As soon as the power supply of the converter has
been activated, a 2 second display test is carried
out, where all characters on the display are
shown (Fig. A5, item 6).
