Internal UPS Battery Connections

The UPS internal batteries will be connected at the factory, EXCEPT the Anderson connections between the shelves and to the fuses.

! WARNING

The DC bus is live when this internal battery connection is made. This connection is to be performed ONLY by Liebert Global Services at startup.

Observe the battery cable polarity. Be sure that the battery connector is made with the cor- rect polarity.

11. Refit all protective covers removed for cable installation

2.2.1Monitor Board Features

Based on your site’s specific needs, the UPS may require auxiliary connections to manage the battery system (external battery circuit breaker, battery temperature sensor), communicate with a personal computer or provide alarm signaling to external devices or for Remote Emergency Power Off (REPO). The monitor board, arranged for this purpose, is located on the rear of the operator access door. The main features are:

•Input and Output dry contacts signal (one pair of contacts of relay)

•Emergency Power Off control (EPO)

•Environmental parameter input interface

•User communication (for data setting and user background monitor)

•Intellislot™ interface

•Modem interface

•Temperature detect interface

Figure 6 shows the relationship and connection between the monitoring (U2) board and other boards in the UPS.
