95.08 DC switch
monitoring
(Only visible with a ZCU control unit)
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:
• By default, DIIL is the input for the Run enable signal.
Adjust 20.12 Run enable 1 source if necessary.
• An internal charging circuit is standard on some inverter
module types but optional on others; check with your local
ABB representative.

95.09 Switch fuse
controller
(Only visible with a BCU control unit)
Activates communication to a xSFC charging 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 charging controller. On units without a DC
switch, this parameter should be set to Disable.
The charging controller monitors the charging of the inverter
unit, and sends an enable command when the charging has
finished (ie. DC switch is closed after the ‘charging OK’ lamp
lights, and charging switch opened).
For more information, see xSFC documentation.
