2.4.2.3.1 PARALLEL CONFIGURATIONS USING DIP SWITCHES TO CONNECT SENSE LINES IN
PARALLEL AND EXTERNAL WIRES TO CONFIGURE LOCAL SENSING
Figure 2-7 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) (see Figure 2-1).
2. For each DIP switch between parallel-connected slots, set DIP switch positions 3 and 4 to
ON (closed) to connect sense leads in parallel (see Figure 2-1).
3. For each DIP switch between parallel-connected slots configure position 5 to connect the
current share bus by referring to PAR. 2.4.2.2.
4. Locate DIP switch(es) at both ends of the parallel group and set positions 3, 4, and 5 to OFF
(open) to isolate the group. (see Figure 2-1).
5. Configure Positions 6, 7, and 8 (alarms) of each DIP switch per PAR. 2.4.4.
6. Connect wire between I/O mating connector pin Sense (+) and corresponding power supply
V(+) terminal at DC OUTPUT terminal block.
7. Connect wire between I/O mating connector pin Sense (–) and corresponding power supply
V(–) terminal at DC OUTPUT terminal block.
