Use an electrical isolating device in the mains
supply cable, such as a mains switch, to switch off
the pump independently of the entire installation
(e.g. for repairs).
1.
Install a motor protection switch, as the motors have no fuse.
2.
Install an emergency cut-off switch or include the motor in the
system's emergency cut-off management scheme.
3.
Only connect the motor to the power supply using a suitable
cable.

Key motor data can be found on the nameplate
and in the "Technical data” chapter.
–
The terminal wiring diagram is located in the
terminal box.
Motor data sheets, special motors, special motor
flanges, external fan, temperature monitoring
–
For further information on the motor with iden‐
tity code specification "S", refer to our website
www.prominent.com. Motor data sheets can be
requested for all other motors.
–
With motors other than those with identity code
specifications "S", "M" or "N": Pay special
attention to the operating instructions for the
motors.
–
Special motors or special motor flanges are
available on request.
CAUTION!
Provide a separate power supply for the external
fan for motors with external fans (identity code
specification "R" or "Z").
Connect the motor as per the wiring diagram for the controller, if it
is controlled by an electronic control unit (such as direct current
motors by a frequency converter).
Connect the motors in accordance with the enclosed wiring dia‐
gram or as per the wiring diagram fixed to the inside of the
housing.
CAUTION!
Only operate stroke length actuators / control
