5.4.3 Direction of rotation
The motors are configured for clockwise and anti-clockwise rotation as standard.
Clockwise rotation Connecting the motor cables in the phase sequence to U1, V1 and W1 of the
frequency inverter (PumpDrive) results in clockwise rotation (looking at the drive-end
shaft end).
Anti-clockwise rotation Interchanging two connections results in anti-clockwise rotation.
The parameter settings for the frequency inverter can be altered to reverse the
direction of rotation without changing a connection. See the relevant operating
manual for PumpDrive 2 or PumpDrive R.
5.5 Tightening torques
Conductor glands in the terminal box
DANGER
Damage to insulation of conductors (cores)
Danger from electric shock!
Damage to the motor!
▷ Adjust the tightening torques for the conductor insulation.
▷ Do not exceed the tightening torques.
For cable glands made from metal and plastic for establishing a direct connection to
a drive, and for other glands (e.g. reducers), refer to the following table to apply the
correct tightening torques.
