5.0OPERATION

The Liebert LDM is a factory-installed option to provide monitoring of the main breaker, branch cir- cuit breakers and subfeed breakers. It may be installed in the Liebert PPC Precision Power Center, Liebert FDC, Liebert FPC and Liebert RDC Remote Distribution Cabinet.

Software available on Liebert’s Web site (see 5.3 - Downloading the Software) can be installed on a desktop or laptop computer (PC) to monitor status and configure breaker parameters and alarm set- points. These monitoring and configuration functions are described in 5.4 - Using the Monitor Tool and 5.5 - Using the Configuration Tool.

The Liebert LDM monitors and displays the parameters listed in Table 5.
