7.17.10 Phase reversal protection
This protection senses if the phases are connected
incorrectly.
The order in which the phases are connected to the
in-stream power has no effect on the Softstarter, but it
may be relevant to the motor, which is connected to the
Softstarter. The motor can for example run in the wrong
direction if the phases are connected incorrectly. This
protection senses if the phases are connected in the
wrong order and then prevents the engine from starting.
