Zero Energy State
NOTE: ZERO ENERGY STATE
To perform service, maintenance and repairs you must disconnect the
RigMaster from its battery source. In the recommended installation
configuration, the RigMaster shares the battery bank with the vehicle's main
engine. Unplug the J1 harness at the power module before disconnecting the
battery cables. After disconnecting the battery cables, check the battery posts
inside the RigMaster engine cabinet to confirm there is no voltage to the
auxiliary power unit (APU).

WARNING! SAFETY COVER SWITCH
It is critical that this safety cover switch is never bypassed; failure to comply
may result in serious injury.
The safety cover switch (Figure

starting when the engine cover
is loose or has been removed.
When the cover is down, the
switch is in the closed position.
When the cover is open or
loose, the switch is in the open
position. The switch is located
at the very top of the unit
enclosure near to main wire
harness plate.
