Connecting the motor
Installation, removal and connection
1. Check the linear offset of the coupling using a slide gauge or feeler gauge.
If the limit values of the above table are exceeded, loosen the fastening of the pump or motor and
move the pump or motor in order to adjust the linear offset.
2. Check the lateral offset of the coupling using a hairline gauge and feeler gauge. Check several
points along the periphery of the coupling.
If the limit values of the above table are exceeded, loosen the fastening of the pump or motor and
move the pump or motor in order to reduce the lateral offset.
3. Check the angular offset of the coupling using a hairline gauge.
If the limit values of the above table are exceeded, loosen the fastening of the pump or motor and
move the pump or motor in order to reduce the angular offset.
Connecting the motor
1. Observe the operating instructions of the motor.
2. Ensure that the operating data on the rating plate of the motor agree with the operating data of the
pump and with the local power supply.
3. Connect the motor in the motor terminal block in accordance with the circuit diagram.
CAUTION
Incorrect alignment of the shaft coupling causes noise, vibrations and damage to the coupling and
bearing.
► After the mounting check the alignment of the coupling.
DANGER
Risk of death resulting from electric shock.
► The motor may only be connected by an authorized electrician.
► Ensure that the power supply is de-energized.
► Ground the pump carefully.
