Relay Contacts

The UPS incorporates a programmable relay output with potential free
contacts for remote alarm indications (see Figure 32 on page 53). An
additional four relay outputs can be obtained with the X-Slot compatible
Relay Interface Card.
The relay contacts must not be connected to any utility connected circuits.
Reinforced insulation to the utility is required. The relay contacts must have a
maximum rating of 30 Vdc/1A and 60 Vdc/2A nominal values.

Programmable Signal Inputs

The UPS incorporates two programmable signal inputs (see Figure 32 on
page 53). Use of non-polar (relay) control input is recommended. The
pins must be shorted with maximum resistance of 10 ohm in order to
activate the specific input.
NOTE
See Figure 39 on page 61 for the polarity and verify these
connections if polarity control is required.
The default and programmable settings for the signal inputs are shown in
Table 11.
