Commissioning steps:

Connect the line contactor control contact to DI/DO 8.

Note

Note the current carrying capacity of the digital output (see the Equipment Manual). A line contactor may have to be used.

Parameterize DI/DO 8 as an output (p728.8 = 1).

Assign p0738 the control signal for the line contactor r0863.1.

Connect the line contactor feedback contact to DI/DO 9.

Assign p0860 an inverted input signal r0723.9.

Enter the monitoring time for the line contactor (100 ms) in p0861.
