Dual unit
Wiring to a XRC
G4
6990 dual unit is reflected by two termination panels on the rear of the enclosure, two XRC
G4
boards in the
interior and two display and local communication ports on the front. Likewise, if units are configured for the optional keypad,
there will be two separate keypads on the front.
Since wiring for the dual unit configuration is identical for each unit, all discussions will focus on the single unit configuration.
Figure 40 shows the single and dual unit termination panel.
