1.
Use Class 1 wiring methods (as defined by the NEC) for interface wiring.
2.
Use Class 2 wiring methods (as defined by the NEC) for interface wiring from 30 to 600V.
3.
When installing external interface wiring (for example, 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-supplied. Use twisted-pair wires for each alarm input and common.
6.
The building alarms can be programmed to display the alarm functional name.
7.
See Table R through Table X 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.
