Operation Manual

GENERATOR INSTALLATION
In RECREATIONAL VEHICLES
INTRODUCTION
Use this section as a guide when installing a generator set in a recreational vehicle, and then refer
to the appropriate operation section for specific instructions. When installing a EC generator set the
installation must comply with the current Safety Standards of ANSI / RVIA EGS-1-2003, ANSI A 119.2
/ NFPA 501C and applicable articles of ANSI / NFPA 70 of the National Electrical Code. Generator set
installations must also comply with state and local requirements.
MARINE APPLICATION
EC generator sets do not comply with United States Coast Guard (USCG) requirements and must
not be used for marine applications. Use only generator sets specified for marine use in marine
installations. USCG regulation 33CFR183 requires a generator set to be “ignition protected” when used
in a gasoline fueled environment.
GENERAL INFORMATION
This information section covers the EC generator set models listed below. To determine which
model is involved, check the model number found on the Power Technology nameplate attached to the
frame of the generator being installed. Follow all instructions to ensure proper installation and operation.
Each generator set features a Kubota diesel engine, rotating-field alternating current generator,
and a control box. The generator is directly connected to the engine for permanent alignment. Each
control box includes a Start / Stop switch, and a On /Off switch to reset the control module or lockout
any remote switch to prevent starting while service is being performed. After the set is attached to the
frame of the vehicle, all that is usually required to make it operational is the following.
1. Attaching the exhaust system.
2. Add proper amount of radiator coolant.
3. Add oil to crankcase, to the dipstick FULL mark.
4. Connect fuel lines, remote switch, load leads and battery terminals.
