unlocked before free movement is possible. There is a “pull” cable (Figure 7-18) in the
external compartment in front of the front tire on the driver’s side—pulling this cable
will release the slide lock for the generator.
Prior to starting or stopping the generator, make sure that all the 120 VAC appliances
are turned “off.” After the generator has been started, wait until the transfer switch
has connected before turning “on” any of the appliances.
The generator can be started from either the remote-start switch located on the dash
or directly at the generator itself. The hour meter installed on the generator records
the number of hours of operation of the generator motor—this elapsed time is needed
for observing necessary maintenance schedules on the generator.

For more detailed operating instructions of the generator and to determine necessary preventive-maintenance
schedules and procedures, review the manufacturer owner’s manual.
Automatic Transfer Switch
The automatic transfer box switches AC power from shore to generator to the coach main distribution panel. This is
achieved by the closing and opening of contactors that are located in the box interior (see diagram on Automatic
Transfer Switch which is located in owner’s information package). Power from shore is fed through contacts located on
R4 and R5. Power input is sensed by electrical board B1. If shoreline neutral is present it will allow relay R1 to energize
which energizes relays R2 and R3 applying shore power to the main control box located in the motor home. If the unit
senses that an open neutral condition exists, R1 will not energize not allowing the coach to receive the potentially
appliance damaging voltage. Power from the generator is sensed by boar d B1 and after a delay of 15-20 seconds, R4
and R5 energize automatically disconnecting shore power B1 checks for generator neutral and if present allow R2 and
R3 to energize allowing generator power to the main control panel.

Caution
Failure to turn “off” the 120 VAC appliances when
starting or stopping the generator
may damage the transfer switch and/or electrical
appliances.
