For both local and remote sensing Positions 1 and 2 of each DIP switch in the parallel configura-
tion must be set to OFF (open); refer to Figure 1-3 to identify the DIP switch associated with a
corresponding slot.
See the following paragraphs for more details:
• PAR. 2.4.2.5.1: Parallel configurations using DIP switches to connect the sense lines in par-
allel and external wires to configure local or remote sensing.
• PAR. 2.4.2.5.2: Parallel configurations using external wires to connect the sense lines in
parallel and external wires to configure local or remote sensing.
2.4.2.5.1 PARALLEL CONFIGURATION USING DIP SWITCHES TO CONNECT SENSE LINES IN
PARALLEL
Figure 2-9 is a simplified diagram of a typical parallel configuration using local sensing via exter-
nal wires to connect V(+) to S(+), V(–) to S(–) and DIP switch settings to connect the sense
leads in parallel. This configuration requires the following:
1. For each supply in parallel set DIP switch positions 1 and 2 to OFF (open).
2. For each DIP switch between parallel-connected slots (DIP 2), set DIP switch positions 3
and 4 to ON (closed) to connect sense leads in parallel.
3. For each DIP switch between parallel-connected slots configure position 5 to connect the
current share bus by referring to PAR. and 2.4.2.4).
4. Configure Positions 6, 7, and 8 (alarms) of each DIP switch per PAR. 2.5.
5. For local sensing connect wire between one I/O mating connector pin 3 (S+) or Euro Mating
plug (S+) and corresponding power supply (+) output terminal or bus bar. For remote sens-
ing connect wire between one I/O mating connector pin 3 (S+) or Euro Mating plug (S+) and
corresponding load (+) terminal.
6. For local sensing connect wire between one I/O mating connector pin 11 (S–) or Euro Mating
plug (S–) and corresponding power supply (–) output terminal or bus bar. For remote sensing
connect wire between one I/O mating connector pin 11 (S–) or Euro Mating plug (S–) and
corresponding load (–) terminal.
