Read and understand the following notes while planning and performing the installation:

Install the interface wiring (for example, building alarm, relay output, battery breaker trip, and X-Slot) separate from the power wiring.The wiring should have double insulation and rated at Uo/U = 300/500 Volts.

All interface wiring is to be provided by the customer.

When installing internal interface wiring to X-Slot terminals, route the wiring through the internal opening in the X-Slot communication bay.

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.

The building alarms can be programmed to display the alarm functional name.

LAN and telephone drops for use with X-Slot cards must be provided by facility planners or the customer.

The UPS Battery Aux and 48 Vdc ShuntTrip signal wiring from the UPS must be connected to the DC source disconnect device.

Battery Aux and 48 Vdc ShuntTrip wiring should be a minimum of 1.5 mm2.

The Remote EPO feature opens all contactors in the UPS cabinet and isolates power from your critical load. Local electrical codes may also require tripping upstream protective devices to the UPS.

The Remote EPO switch must be a dedicated switch not tied to any other circuits.

A jumper wire must be connected between pins 1 and 2 onTB1, if the normally-closed Remote EPO contact is not used.

Remote EPO wiring should be a minimum of 0.75 mm2 and a maximum of 2.5 mm2.

The maximum distance between the Remote EPO and the UPS cannot exceed 150 meters.

Alarm relay contacts have a maximum current rating of 5A and a switched voltage rating of 30 Vac and 28 Vdc.

Alarm relay wiring should be a minimum of 0.75 mm2.
