Liebert SiteLink interface. ® The Liebert LDMF consists of a monitor board, interface board, optional local display and Branch Sensor Modules (BSM). The Liebert LDMF is capable of receiving input from current branch sensor modules. The sensor module (BSM) contains 100A current transformers (CTs) encapsulated in an epoxy-filled plastic enclosure designed to be mounted next to the panelboard.
• A DB9 serial port on the outside panel is available for local configuration. PM4 Interface Board (PIB) The Liebert LDMF PM4 Interface Board (PIB) provides connections for the voltage and currents of the panelboard main circuit breaker as well as the CT current for any installed large branches or subfeed breakers (maximum of 18 CTs).
1A secondary CT will damage the PIB and the CT. To ensure the proper current ratio and accuracy, the CTs should be purchased through Vertiv. See Table 1 for details. Contact your local Vertiv representative or call Vertiv Support at 800-543-2378.

Connecting anything other than a 1A secondary CT will damage the PLIB and the CT. To ensure the proper current ratio and accuracy, the CTs should be purchased through Vertiv. See Table 1 for details. Contact your local Vertiv representative or call Vertiv Support at 800-543-2378.

LDMF summary alarm contacts. • If two Liebert LDMF systems are provided, the two PABs are connected to each other at the factory. It is only necessary to connect to one PAB to monitor the Customer Summary Alarm; the two Liebert LDMF units share summary alarm contacts.
Off and locked-out in accordance with NEC and local/state code. NOTE Liebert LDMF components and any other monitoring devices should be installed only by properly trained and qualified personnel. This section provides instructions for installing and connecting Liebert LDMF current transformers.
To configure the branch circuits, refer to 5.5.11 - Add a Circuit Breaker. NOTE • Panelboard A is either Panelboard 1 or Panelboard 3. • Panelboard B is either Panelboard 2 or Panelboard 4 depending on which Liebert LDMF Control Board is being configured. Installing a Solid-Core Current Transformer WARNING A solid-core CT cannot be installed on a wire while current is flowing through the wire.
If the Power Distribution Center is supplied with optional isolated ground, the isolated ground circuit can be monitored by the Liebert LDMF. Usually the CT is already installed and wired to the Large Branch Terminal Block at the factory. If not, perform the following steps: (For Isolated Ground CT Installation only) •...

5.0 OPERATION The Liebert LDMF is a factory-installed option to provide monitoring of the main breaker, branch circuit breakers and subfeed breakers. It may be installed in the Liebert PPC, Liebert FDC, Liebert FPC. Liebert RX and the Liebert RDC.
Alarms The Liebert LDMF constantly monitors electrical data for each breaker and subfeed. When the unit detects an alarm condition, it annunciates and displays alarm messages via the Monitor program (see 5.4 - Using the Monitor Tool (Used Only for Startup and Diagnostics)) as well as showing the alarm on the local display (if installed).
