rate prior to shedding any loads. Working together, an inverter assist feature is available. Normally the
inverter is at rest when shore power is available. EMS utilizes the inverter and the coach battery bank to
smooth out peak load demands. The inverter assist feature scales back the charge rate in order to have
more 120VAC power available for the appliances.
ELECTRICAL POWER CORD REEL
The electric power cord reel (Figure 8-14), allows you to
manually extract the power cord reel as needed. To retract
the power cord, hold the switch until the power cord is fully
retracted.

AUTOMATIC TRANSFER SWITCH

The automatic transfer box switches 120V AC power from shore or generator to the coach's main dis-
tribution panel. The transfer box has a delay of around three seconds before switching power to shore,
and a delay of around 30 seconds before switching power to the generator.
If the unit is plugged into shore but no power to coach then make sure the shore outlet has power.
If power is present this may indicate the unit is sensing an open neutral condition. Start the generator,
if the power is restored, then either the shore plug or the outlet may be defective (the neutral line may
be broken.)
If there is no power to coach from shore or generator then check the generator circuit breaker. If the
circuit breakers are not tripped in the generator or the coach, the transfer box may need to be replaced.
For more detailed information on the automatic transfer switch, please refer to the specific owner's
instructions found in the owner's information package.
