Basic diagram with by-pass control and isolation contactor
REMARKS:
(1) The isolation contactor M1, is not required to perform operation to the motor.
Be aware however that M1 provides galvanic isolation from the incoming line increasing the safety.
(2) The output relays allow for direct action on contactors according ratings specified in page 3-2 of this
manual.
(3) By-pass control uses function "zxxx" and on contactor M2. Details given below.
By-pass control.
1. The by-pass function has been enabled by setting "zxxx" to ON. In this case the by-pass is automatically
done after starting. This relay must be used to control the by-pass contactor.
