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 emer‐
gency cut-off management plan for the system.
3. Only connect the motor to the voltage supply using a suitable cable.
–
Key motor data can be found on the nameplate.
–
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 for the motor with identity code
specification "S", refer to the motor data sheet in the
Appendix. Motor data sheets can be requested for all
other motors.
–
For motors other than those with identity code specifica‐
tions "S", "M" or "N": Pay special attention to the oper‐
ating instructions for the motors.
–
Special motors or special motor flanges are possible on
request.
CAUTION!
Provide a separate power supply for the external fan with
motors with external fans (identity code specification "R" or
"Z").
Connect up 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 as per the enclosed wiring diagram or the wiring dia‐
gram on the inside of the housing.
CAUTION!
Only operate stroke length actuators / control drives when
the pump is running!
Otherwise they will be damaged.
WARNING!
Risk of electric shock
In event of a defect, there is a risk of electric shock when
conductive feed chemical are used.
– For safety reasons we recommend connecting to a pro‐
tective low voltage, e.g. in accordance with EN 60335-1
(SELV ).
External fans
Variable speed motors with frequency
converter
