5.4 Special Terminal Connections
This section describes the special-purpose terminal connections of the Power+.
5.4.1 Special Terminal Connections on 50 kVA Units
On the 50 kVA model, 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 32 shows a view from above of the open static switch tray and the location of the special
terminal connections. Figure 33 provides a closer look at the connections.
Note: There are also some special purpose connections on the rear of the controller module.
