Specified wiring and the MOB and SLB breakers for the UPS Sidecar are
rated for parallel redundant service only. DO NOT use as a parallel
capacity system.
C A U T I O N
Parallel system wiring length should be in accordance with the parallel
drawings found in the appendix of the applicable Powerware 9390
installation and operation manual, listed in paragraph 1.5. Correct wire
length ensures approximate equal current sharing when in Static bypass
mode.
3. For external input wiring, use 90°C copper wire. See the appropriate column in Table B
through Table E. Wire sizes are based on using the specified breakers.
4. Wire ampacities are chosen from Table 310---16 of the NEC. Input wire is 90°C
specification.
5. If a Bypass Input Breaker is not installed, a minimum of two separate feeds with upstream
feeder breakers, or one feed with two upstream feeder breakers, must be provided: one
for the UPS and one for the UPS Sidecar bypass input. DO NOT use one feed or a
single-feeder breaker to supply both the UPS and Sidecar.

terminations. Drawing 164201546---6, starting on page A---30, shows the location of the
power cable terminals inside the UPS Sidecar cabinet.
10. Per NEC article 300-20(a), all three
-
phase conductors must be run in the same conduit.
Neutral and ground must be run in the same conduit as the phase conductors.
11. If input or output neutrals are required for Maintenance Bypass configurations, wire the
neutrals to the neutral terminals located inside the UPS cabinet. For Maintenance Bypass
configurations, wire grounds to the ground terminals located inside the UPS cabinet.
12. 40/20 kVA and 40/30 kVA parallel systems must be wired for 40/40 kVA.
