5.3 Electrical connections
The electric connections and inspections have to be carried out by a
qualified electrician and have to comply with the relevant local standards.
• The electric characteristics (frequency, voltage, nominal current) of
he motor-converter are mentioned on the name plate. Check that the
t
motor-converter complies with the mains supply used.
• The electric protection of the motors 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-item11).
• If you have to install a differential circuit-breaker for users protection,
it must have a delay effect. Adjust it according to the current mentioned on the converter label.
• Use power cables conforming with standards
DO NOT FORGET TO CONNECT TO EARTH.
• The electric connection of the converter (fig.6) has to comply with the
ear the weight of the pipes.

CAUTION !
Before any operation,
switch off the pump(s).
8. Defaults-Causes-Remedies
Before carrying out any maintenance work, switch off the
pump and ensure that it cannot be switched on again by
unauthorised people.
CAUTION !
Never carry out work on a running pump.
No special maintenance in operation.
Keep the pump and the motor-converter perfectly clean.
In case of prolonged stopping, if there is no risk of frost, it is best not
to drain the pump.
The bearing holding the coupling and the motor bearings are lubricated
for their total lifetime and do not require any lubrication.
On pumps equipped with greaser under bearing box, see regreasing
instructions written on sticker put on it.
MVIE 7004
MVIE 9503/2
On other models, the bearing holding the coupling is lubricated for its
total lifetime.
It is recommended to grease the shaft end as well as the coupling
boring with a high adhering grease (type type D321R Molikote or 8191
Loctite for example) to facilitate any further diassembling.
The mechanical seal does not require any maintenance in operation. It
must never operate dry.
