Once that is complete, turn the board over and, if necessary, remove the
short ribbon cable connected to J64 on the interface card to get access to
the under side of the PCB. You can now scan the board and refer to Figure
2-3 to locate the various components and jumpers on the PCB. Once you
have made the necessary changes, reconnect the ribbon cable, screw the
PCB back in place, and screw the top cover on.
Procedure for 2.8kW XFR
Ensure that the input power connection has been disconnected and
the unit is powered off before you attempt to remove the top cover.
Remove all the screws holding down the top cover and then remove
the cover. The printed circuit board that you need access to is right
side up (component side up), so refer to Figure 2-3 to locate the
various components and jumpers on the PCB. Once you have
located the jumpers and made the necessary changes, return the top
cover to its proper position, and screw it back in place.
