Commissioning and decommissioning
6.1.1 Checking the rotation direction
The drive shaft direction of rotation is shown by
the rotation direction arrow (Fig. 2/O) on the mo-
tor fl ange.
a) Start the motor briefl y (max. two seconds) to
check the direction of rotation. When looking at
the motor fan, it must rotate anti-clockwise.
NOTICE
Incorrect direction of rotation
Operating in the wrong direction of rotation leads
to damage to the machine.
Use a phase sequence indicator to check the direc-
tion of rotation (clockwise rotating fi eld).
b) After correcting the direction of rotation if nec-
essary, start the motor again and stop it again
after 2 minutes in order to top missing oil up to
the upper edge of the sight glass (Fig. 2/I). This
topping up at the fi lling point (Fig. 2/H) must be
repeated until all the oil pipes have been fi lled
completely. The fi lling point must not be open
when the pump is running.
