Special Terminal Connections

This section describes the special-purpose terminal connections of the POWER+ RM 50 kVA.

Special-purpose connections are located inside the static switch tray. To access the special-
purpose terminals, the static switch tray must be partially slid out (after disconnection of the UPS
from all voltage sources and following standard safety procedures). Figure 34 shows a view from
above of the open static switch tray and the location of the special terminal connections. Figure
35 provides a closer look at the connections.

Note: There are also some special purpose connections on the rear of the controller module.
