):
a.) Interrupt the "Connect" signal for the power circuit breaker.
b.) The mains voltage (synchronization voltage) must be within the permissible limits.
c.) In the moment a connection command is output, the differential voltage between the corresponding
conductors must be equal to zero. This check must be carried out for all three phases, in order to
check the correctness of the rotating field.
d.) After a successful check, the "Connect" signal can be connected again.

Check the dead bus start function
Prior to checking the dead bus start function, the output of the "Connect" signal must be interrupted.

If steps 1 through 7 have been carried out successfully, parallel operations may be commenced. It is rec-
ommended to start with a constant power/baseload operation (approx. 25 % of the generator rated power)
initially. While this operation is being carried out, the displayed measured values must be verified. Test
the GCB shutdown. Check the real power controller and if necessary the power factor controller for
proper operation. Enter various set point values and verify proper operation.
