Replacement of AC Board
To replace the AC board (SPARE-502):
1. Before beginning, remove the SMA cable for the antenna wire. See
A
in Figure 39. Note that this is not
a required step for board replacement, but will make access to the board easier.
2. Unclip all wires from AC terminals at the bottom of the board, including the neutral wire. See
B
.
IMPORTANT:
Mark or note the wire positions so that they can be reinstalled correctly. The wire
positions on the terminals do not correspond to their positions on the circuit breakers.
This example does not depict generator wiring. If a generator is connected (
B1
and
B2
), these wires must be disconnected as well.
