3. CHECK ROTATIONAL DIRECTION OF
THE ELECTRIC MOTORS
(CONTROL WITHOUT PHASE SEQUENCE
MONITORING)
Check rotational direction of the electric
motors prior to commissioning the machine.
This is marked on new machines by arrows on
the fan blowers of the motor.
The rotational direction is always clockwise on
the ventilators (clockwise direction). See Fig. 1.
- Switch on motor briefly.
- Check rotational direction by looking at the
fan wheel.
- Switch phases if in the wrong direction.
DANGER
ELECTRIC SHOCK
It is imperative to switch main switch into 0-
position and pull mains plug.
- Recheck rotational direction.
The rotational direction should always be
checked:
- After the connection,
- After repairs to the electrical system,
- After changing the supply cable or parts of
the cables,
- After an extension of the supply line by
additional cables.

4. CHECK ROTATIONAL DIRECTION OF
THE ELECTRIC MOTORS
(CONTROL WITH PHASE SEQUENCE
MONITORING)
For machines with a control whereby the
phase sequence is monitored, it is not
necessary to check the rotational direction.
If the phase sequence is incorrect, the motor
will not start.
Have authorised personnel replace the phase
sequence.
Repeat the start-up procedure.
