OtOr
Before the power is connected to the motor, position the
terminal stripe jumpers according the mains power volt-
age (230 V, 400 V, 460 V).
After the power has been connected to the motor
the direction of rotation of the working spindle has
to be checked. If the direction of rotation is incorrect, re-
verse the direction by exchanging any two power wires.
2.3.2 p
rOximity switch
The proximity switches are supplied (feed voltage 24
VDC) by a separate power supply or the higher level con-
troller. The machine is provided with inductive or pneu-
matic signaling elements alternatively.
Loosen the screws and remove the cover.
The electronic or pneumatic proximity switches are set at
the factory.
