Powerware 100160 kVA manual Description Interface Wiring Installation

Installation Information

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 (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.
