Description
Enables/disables DC switch monitoring via the DIIL input.
This setting is intended for use with inverter modules with an
internal charging circuit that are connected to the DC bus
through a DC switch.
An auxiliary contact of the DC switch must be wired to the
DIIL input so that the input switches off when the DC switch
is opened.

If the DC switch is opened with the inverter running, the
inverter is given a coast-to-stop command, and its charging
circuit activated.
Starting the inverter is prevented until the DC switch is
closed and the DC circuit in the inverter unit recharged.
Notes:
