5. Disconnect the existing controller electrical
connections.
a. Remove the controller cover. If access to the
interconnection circuit board on the rear panel
and/or the main logic/communication circuit
board on the front panel is difficult to access,
partially disassemble the controller box.
Remove the two controller panel top screws
and center bottom screw and then loosen the
bottom screw on each side to swing the
controller panel down. See Figure 7-5.
Note: If the controller is panel mounted to the
junction box, remove the access panel
and respective hardware.
Note: Clearly mark all disconnected leads
from the controller with tape to simplify
reconnection.
b. Disconnect the controller harness leads. Listed
below are some common leads and plugs that
require removal or disconnection. Items below
in bold are shown in Figure 7-5 and Figure 7-6.
These connections are typical and may not
apply to all
corresponding wiring diagram found in the
wiring diagrams manual.
