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 46 on page 77). You can obtain an additional four
relay outputs with the X-Slot compatible Relay Interface Card.
W A R N I N G
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.
