being supplied with power. Every effort should be made to identify and correct any fault
that exists.

DANGER
When parked on wet ground, avoid using
an external power source to connect the
cab power plug. Water is a conductor of
electricity. In wet conditions, electrical
shock can occur which can result in
personal injury or death.
The VN 730, 780, 670 and 630 are available with an optional 120 V AC service, used for
longer parking while still living in the vehicle. The 120 V AC service is supplied from
outside sources. To hook up the service, there is a socket located behind the driver side door.
