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.
