ALWAYS switch the battery breaker off before removing or installing the inverter module
assembly.
Handle the inverter module with extreme care. Circuit boards and logic upgrades are static-
sensitive and susceptible to damage.
You can remove the inverter module assembly while the power supply is running on line power. The
power supply will continue to operate as a non-voltage regulated power supply.
NOTE:

1. Reconnect the inverter module ribbon cable
to the Inverter Module circuit board by seating
the cable into the connector (the locking tabs

the inverter module back onto the connector. It
is important the sheet metal is properly seated
in the card guides and fully inserted into the
housing.

battery input, temp probe cables, TMPR and
XPDR cables. Turn the battery breaker on.
