Control Terminals; Relay Output Contacts - Eaton Powerware BladeUPS User Manual

Control Terminals

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.

NOTE If using a semiconductor switch type, pay attention to the proper polarity. A relay or other
mechanical control is preferred.

Relay Output Contacts

The UPS incorporates a programmable relay output with potential free contacts for
remote alarm indications (see Figure 73 on page 107). You can obtain an additional
four relay outputs with the X-Slot compatible Relay Interface Card.
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.
