Automatic Power Transfer Switch - Regency ULTRA Owner's Manual

ELECTRICAL SYSTEM OPERATION
Generator Electrical Safety
WARNING
Exercise extreme care and caution when handling
the generator and its components.
Carelessness can be dangerous and even fatal.
Never touch any electrical leads, equipment, or
appliances when your hands are wet or when you
are standing on wet ground or in water.
Do NOT attempt to repair the generator yourself.
Have all service and repairs performed at an
authorized service center only.
Never check the generator oil level while the
generator engine is running.
WARNING
Asphyxiation
All internal combustion engines produce carbon
monoxide (CO) gas fumes when running. This gas
is poisonous, colorless, odorless, tasteless, and is
lighter than air.
• Do not run the generator and an intake vent fan
at the same time. This could draw gases into the
motorhome.
• Do not open windows or vents on the side where
the generator exhaust pipes are located.
• Park so the wind carries exhaust gases away from
the motorhome. Be aware of potential gas fumes
from other nearby vehicles.

REGENCY ULTRA MOTORHOME
• Do not operate the generator if there are any
obstructions such as vegetation, snow, buildings,
etc. which could deflect gas fumes under or into
the motorhome.

AUTOMATIC POWER TRANSFER SWITCH

Automatic Switch Over
Start the generator to automatically switch over
from 120-Volt AC shore power to generator power.
Built-In Delay
A 20–30 second delay prevents the generator from
starting while under load. This delay allows the
generator to have the required amount of warm-up
time before transferring power.
This switch automatically transfers power when
switching between 120volt shore power and
generator power, and prevents damage to any
circuitry if the shore power and generator are
inadvertently operated simultaneously.
NOTICE
Always verify that appliances are turned off
before starting or stopping the generator.
Do NOT start the generator while it is under
load.
Ensuring all appliances are in the off position will
help prolong the life of these systems.
