For a double circuit-breaker bay, the modules DB_BUS_A, DB_LINE and
DB_BUS_B must be used.

Configuration setting

For application without QB9 and QC9, just set the appropriate inputs to open state
and disregard the outputs. In the functional block diagram, 0 and 1 are designated
0=FALSE and 1=TRUE:
• QB9_OP = 1
• QB9_CL = 0
• QC9_OP = 1
• QC9_CL = 0
If, in this case, line voltage supervision is added, then rather than setting QB9 to
open state, specify the state of the voltage supervision:
• QB9_OP = VOLT_OFF
• QB9_CL = VOLT_ON
If there is no voltage supervision, then set the corresponding inputs as follows:
• VOLT_OFF = 1
• VOLT_ON = 0
