Installation, care and maintenance
Minette
Electrical connections
All electrical work shall be carried out under the
supervision of an authorized electrician.
Local codes and regulations shall be complied
with.
Check that the mains voltage and frequency
agree with the specifications on the pump data
plate.
NOTE! For safety reasons, the earth (ground)
lead should be longer than the phase and moni-
toring leads. If the motor cable is jerked loose
by mistake, the earth (ground) lead should be
the last lead to come loose from its terminal.
This applies to both ends of the cable.
Make sure that the pump is correctly earthed
(grounded).
When the pump is connected to the public mains
it may cause flicker of incandescent lamps when
starting. In this case the supply authority should
be notified before installing the pump.
WARNING!
All electrical equipment must
be earthed (grounded). This
applies to both pump equip
-
ment and any monitoring
equipment. Failure to heed
this warning may cause a le-
thal accident. Make sure that
the earth (ground) lead is cor-
rectly connected by testing it.
NOTE!
Make sure that the monitoring
equipment incorporated in the
product is correctly connected
and in use.
WARNING!
If the pump is equipped with
automatic level control or con-
tactor unit, there is a risk of
sudden restart.
WARNING!
Bear in mind the risk of elec-
trical shock if the electrical
connections are not correctly
carried out or if there is fault
or damage on the pump.
Start and stop of the pump at different water
levels may be manual or automatic. If automatic
start and stop is required, a level regulator can
be ordered (as option).
Level regulators are available in 1 phase for both
50 Hz and 60 Hz markets.
The level regulator can be set at different oper-
ating levels by adjusting the length of cable. A
clamping bracket situated at the discharge con-
nection holds the level regulator cable in place.
If continuous pumping is required at any time
the level regulator can be placed in a special
rubber bracket on the discharge connection thus
eliminating the level regulator function.

NOTE!
If cable with ground check
is used for pump with level
regulator, the ground check
connection must be done at
the GC-connection point with
a stud and two nuts.
