3. Acquire display data from the old controller for
reference purposes.
When possible, write down the old controller
display data in Section 5.3.6 and Section 5.3.7,
User-Defined Settings. This data is not required for
the new controller but may be needed for future
reference. If the old controller is not functional, the
information is no longer retrievable.

a. Place the generator set master switch in the
OFF position.

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 5-5.
Note: Clearly mark all disconnected leads
from the controller with tape to simplify
reconnection.
