Accessory Modules
See Figure 1-22 through Figure 1-26 for connection
options with up to three accessory modules. Accessory
modules can include one Model RXT transfer switch,
one programmable interface module (PIM), and/or one
load control module (LCM).
See Figure 1-21 for the maximum total cable length with
1, 2, or 3 accessory modules per cable run.
D Use Belden #9402 (4-conductor) or equivalent 20
AWG shielded, twisted-pair cable. Note the shield
connections shown in Figure 1-22.
D Belden #8723 (2-conductor) shielded twisted-pair
cable can be used for connections A and B, and
#12--14 AWG wire can be used for the COM and PWR
connections. The maximum total cable length is the
value shown for #12 or #14 AWG wire in Figure 1-21.
