2.4.2.5.2 PARALLEL CONFIGURATIONS USING EXTERNAL WIRES TO CONNECT SENSE LINES
IN PARALLEL (HSF 300W AND 600W ONLY)
Figure 2-10 is a simplified diagram of a typical parallel configuration using local or remote sens-
ing via external wires to connect V(+) to S(+), V(–) to S(–) and wires connected to the I/O mating
connector 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 in Figure 2-10), set DIP switch
positions 3 and 4 to OFF (open) (sense leads will be connected in parallel in steps 5 and 6).
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. Connect Sense (+) lines in parallel by connecting wires between pin 3 of each I/O mating
connector or between the S+ terminals of the Euro mating plug.
6. Connect Sense (–) lines in parallel by connecting wires between pin 11 of each I/O mating
connector or between the S– terminals of the Euro mating plug.
7. 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.
8. 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.
