CAUTION!
The motor may be damaged
Provide appropriate motor protection devices (e.g. motor pro‐
tection switch with thermal overcurrent trip) to protect the
motor against overloading. Fuses do not provide motor pro‐
tection.
CAUTION!
Only motors with a frequency converter: The motor may be
damaged
If a motor with an integrated frequency converter is restarted
within 3 minutes of switching off of the mains voltage, the
input current limiter could be damaged.
–
After switching off, allow the device to stand for at least 3
minutes before restarting.
–
If the motor is controlled via a control, take this into con‐
sideration at the control.
CAUTION!
The pump can be damaged
The pump can be damaged if the motor drives the pump in
the wrong direction.
–
When wiring the motor, pay attention to the correct direc‐
tion of rotation indicated by the arrow on the fan cover,
as indicated in the diagram.
Install an electrical isolating device in the mains supply
cable, e.g. a mains switch, to be able to switch off the pump
independently of the entire installation (e.g. for repair).
1.
Connect the terminal box of the motor to the power supply and earth
using a suitable cable.
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 power supply using a suitable cable.
Key motor data can be found on the nameplate and in
–
the Chapter "Technical data".
The terminal wiring diagram is located in the terminal
–
box.
Motor data sheets, special motors, special motor flanges,
external fan, temperature monitoring
Motor data sheets can be requested for the 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.
