Connecting the parallel cabinet control cables
2. Fit a parallel adaptor board over the connector JD8 on the interface board (Figure 3.17) in every UPS cabinet.
Note:
The parallel adapter contains two port connectors, JD5 and JD6 and a configuration DIP Switch (SW2)
(see Figure 3.18).
3. Connect JD6 of the parallel adapter in UPS Cabinet 1 to JD5 of the parallel adapter in Cabinet 2 using the
corresponding bus-cable (supplied).
4. Similarly, connect JD6 of the parallel adaptor in UPS Cabinet 2 to JD5 in Cabinet 3.
5. Continue in the same manner for the remaining UPS Cabinets, as illustrated in Figure 3.18.
