9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
1. Use Class 1 wiring methods (as defined by the NEC) for interface wiring up to 30V. The
wire should be rated at 24V, 1A minimum.
2. Use Class 2 wiring methods (as defined by the NEC) for interface wiring from 30 to 600V.
3. When installing external interface wiring (e.g., building alarm, relay output, battery breaker
trip, and X---Slot) to the UPS interface terminals, conduit must be installed between each
device and the UPS cabinet. Install the interface wiring in separate conduit from the power
wiring.
4. When installing internal interface wiring to X---Slot terminals, route the wiring through the
internal opening in the X---Slot communication bay.
5. All building alarm inputs or remote features require an isolated normally-open contact or
switch (rated at 24 Vdc, 20 mA minimum) connected between the alarm input and
common terminal as shown. All control wiring and relay and switch contacts are customer
provided.
6. Regardless of assignment, alarms display as Building Alarm 1 and Building Alarm 2,
on the Control Panel Display Screen. Use twisted---pair wires for each alarm input and
common.
7. See Table T through Table Y and Chapters 3, 5, and 6 for customer interface wiring.
8. LAN and telephone drops for use with X---Slot connectivity cards must be provided by
facility planners or the customer.
