Connect the cables to the control terminals with a mating connector. Input and output terminals have a
functional isolation from terminal to terminal. They are connected to the UPS through individual 1 MΩ resistors.

The UPS incorporates a programmable relay output with potential free contacts for remote alarm indications
(see
Figure 78 ). You can obtain an additional four relay outputs with the X-Slot compatible Relay Interface Card.
CAUTION
The relay output contacts must not be connected to any utility connected circuits; the utility requires reinforced
insulation. The relay output contacts have a maximum rating of 30 Vac/1A and 60 Vdc/2A nominal values.
