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.

Charging logic
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.
Note: By default, DIIL is the input for the Run enable
signal. Adjust 20.12 Run enable 1 source if necessary.
Note: An internal charging circuit is standard on some
inverter module types but optional on others; check
with your local ABB representative.
