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.
Note: An internal charging circuit is standard on some
inverter module types but optional on others; check with your
local ABB representative.
DC switch monitoring through the DIIL input disabled.
DC switch monitoring through the DIIL input enabled.
Activates communication to a BSFC-xx switch fuse controller.
This setting is intended for use with inverter modules that are
connected to a DC bus through a DC switch/charging circuit
controlled by a BSFC-xx switch fuse controller.
The BSFC controls and monitors the charging of the inverter
unit, and sends an enable command when the charging has
finished. When the DC switch is opened, the BSFC stops the
inverter.
For more information, see BSFC documentation.
Communication with BSFC disabled.
Communication with BSFC enabled.
