ELECTRICAL CONNECTION (VX 4.25/0-47)

Connecting the motor
The motor must be connected according to the connection diagram (see
terminal box cover or instruction leaflet in the terminal box).
The permissible connection types of the motor can be found on the
motor type plate.
The motor must be protected by a motor circuit breaker for which the
service factor (SF) must be taken into account. Operation without an
appropriate fuse is prohibited.
Approved direction of rotation of the pump
Before commissioning, check whether the pump is rotating in the
prescribed direction (observe the direction of rotation arrow on the unit
cover).
To do this, start the pump only briefly (max. 3 sec.), as operation with the
wrong direction of rotation will damage the pump.
If the pump does not run in the specified direction of rotation (view of
the motor fan wheel), this must be changed by swapping two connection
phases.
Connecting the motor
The motor must be connected as shown in the following pictures.
The motor must be protected by a motor circuit breaker for which the

appropriate fuse is prohibited.

(ILME CQM 05 pin insert 5+PE-pole).
