5.6.1 Installing customer input signals interface

These inputs are located behind the UPS door, in the top section of the UPS.

See Figure

for the connector locations.

Tie points with strain relief for the communication cables are located on the right

and left side of the cable conduit.

Signal inputs can be configured to different functions. Normally these functions

are either informative (for example, “On Generator”) or functional (for example, a

remote “Go to bypass” command).

5.6.2 Battery breaker wiring interface

When using the original accessory battery cabinet from the manufacturer, the

battery breaker interface wiring is provided with the cabinet. The wiring is

connected to the X5 and X6 terminal in the UPS.

When using a third-party battery system, the breaker must be equipped with

auxiliary signal and should have a 24 V shunt trip for remote opening of the

breaker, when needed.

See Section

5.4.2

for installation instructions.

5.6.3 Relay output interface connections

The general alarm relay is a dry relay signal output. The relay can be used for

informing the operators about UPS alarm conditions, for example through a

building management system. By default, the relay is configured to activate

when the UPS general alarm is active, that is, any event when the

ALARM

status is active. The relay can also be configured to activate by some other

event, but this needs to be done by authorized service personnel.

Relay signal wiring can be installed only through the signal cabling canal, from

back to front, in the top section of the UPS.

Additional relay outputs are available with mini-slot cards. Relay outputs can be

configured to be activated by various events. Configuration can be done by an

authorized Eaton Customer Service Engineer or by other qualified service

personnel authorized by Eaton.

5.6.4 Industrial Relay Card interface connections

Relays K1 through K5 are identical in function. Each output contact function can

be assigned by the user. The UPS information may also be configurable.
