5.5.3

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

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. The relay

rating is 30 V AC or DC, 5 A.

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.

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.

To install the INDRELAY-MS:

Check that the ancillary equipment system is turned off and all the power

sources are removed. Refer to the appropriate operation manual of any

ancillary equipment for shutdown instructions.

Install wiring from the IRC to the monitoring equipment using appropriate

conduits through the cable exit opening in the IRC.

Connect wiring between the IRC terminal blocks and the monitoring

equipment using terminations. Connect one wire to COM (Common) and

another to either NC or NO to select the Normally Open or Normally Closed

option.

Install the INDRELAY-MS into an open MiniSlot communication bay in the

UPS cabinet.
