Relay Output Contacts

The UPS incorporates three programmable relay outputs with potential
free contacts for remote alarm indications: a standard relay port and two
outputs in the RS-232 communication port. See Figure 18 on page 53 for
the locations of the ports. An additional four relay outputs can be
obtained with the compatible Relay Interface Card.
Configure the relay outputs with the "Relay Configuration" setting in
"User Settings" on page 40.
The relay output contacts must not be connected to any utility connected circuits. Reinforced
insulation to the utility is required. The relay output contacts have a maximum rating of
30 Vac/1A and 60 Vdc/2A nominal values.
Table 5 shows the options for the relay output contacts.
