ELECTRICAL CONNECTION (24V DC DRIVE)

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.
Permitted direction of rotation of the pump (3~)
Before commissioning, check that the pump is rotating in the prescribed
direction (observe the direction of rotation arrow on the side 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 exchanging two
connection phases
The motor must be connected as shown in the following pictures.
The motor must be protected by a motor circuit breaker for which the
service factor (SF) must be taken into account.
Operation without appropriate fuse protection is prohibited.
Connecting the control unit
The adjacent illustration shows the terminal assignments of the control
unit and the power supply.
Adjust the DIP switches to the application.
