5.6.2 Connecting the motor
NOTE
In compliance with IEC 60034-8, three-phase motors are always wired for clockwise
rotation (looking at the motor shaft stub).
The pump's direction of rotation is indicated by an arrow on the pump.
1. Match the motor's direction of rotation to that of the pump.
2. Observe the manufacturer's product literature supplied with the motor.
5.7 Checking the direction of rotation
DANGER
Temperature increase resulting from contact between rotating and stationary
components
Explosion hazard!
▷ Never check the direction of rotation by starting up the unfilled pump set.
▷ Prime the pump before checking the direction of rotation.
WARNING
Hands inside the pump casing
Risk of injuries, damage to the pump!
▷
Always disconnect the pump set from the power supply and secure it against
unintentional start-up before inserting your hands or other objects into the
pump.
CAUTION
Drive and pump running in the wrong direction of rotation
Damage to the pump!
▷
Refer to the arrow indicating the direction of rotation on the pump.
▷ Check the direction of rotation. If required, check the electrical connection and
correct the direction of rotation.
The correct direction of rotation of motor and pump is clockwise (seen from the drive
end).
1. Start the motor and stop it again immediately to determine the motor's
direction of rotation.
2. Check the direction of rotation.
The motor's direction of rotation must match the arrow indicating the direction
of rotation on the pump.
