4.0 Determination of the Rotary Field
The phase sequence of the three phases present determines the
rotary direction of the motor connected. The correct phase sequence
L1, L2, L3 results in a clockwise rotation.
For phase sequence determination connect the three clamps L1,
L2, L3 in any order to the three phase system. LED/LCD-Segment
(3) is illuminated for a clockwise rotary field. If LED/LCD-Segment
(2) is illuminated, exchange
two connections.
Please also refer to table
at the backside of the unit
Correct phase sequence is
displayed even if neutral N
is connected instead of L1,
L2 or L3. Correct phase connection has to be verified by two-
pole voltage test.

manual no special maintenance is required.
