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)

•Liebert IntelliSlot® interface

•Modem interface

•Temperature detect interface
