Most electric tools and appliances will have the voltage and
amperage requirements on their individual nameplates.
When in doubt, consult the manufacturer or a local
electrician. The nameplate amperage rating for electric
motors can be misleading. See “Starting Electric Motors” in
the Unit Capabilities.
This generator end is controlled by an AVR. The engine
governor will automatically adjust itself to the load. No
harm to the generator will result if it is operated with no
load connected.
CAUTION: EQUIPMENT DAMAGE
Diesel engines should never be run for an extended
period of time with a very light load or no load on
them, it may do permanent damage to the engine if
run under these conditions.
Proper utilization of the receptacles located on the control
panel is necessary to prevent damage to either the
receptacles or the generator. The generator is a limited
source of electrical power, therefore, pay special attention
to the receptacle and generator ratings. The nameplate
rating can be obtained through a single receptacle as long
as the receptacles amperage rating is not exceeded.
GROUNDING
Proper grounding of your generator is application
dependent. Carefully evaluate your planned use of your
generator to understand which grounding you require.
If you are not sure what to do, contact a competent
professional to assist you. The NFPA 70 250:34-35 are good
technical references.
STANDARD PORTABLE GENERATOR
Your WINCO portable generator ships with a bonded
neutral. You can safely use this generator without external
grounding as long as all loads are powered through the
receptacle panel.
VEHICLE-MOUNTED GENERATOR
Your WINCO portable generator ships with a bonded
neutral. When mounted to a vehicle to safely distribute
power it is necessary that the generator frame is bonded
to the vehicle frame. The generator should only supply
equipment that is cord and plug connected through
receptacles mounted on the generator or the vehicle.
PERMANENTLY INSTALLED GENERATORS
This WINCO portable generator ships with a bonded
neutral and overcurrent protection. NFPA 70 refers to this
as a “separately derived system.” When connecting it to a
building a transfer switch specifically designed for GFCI and
bonded neutral generators is required.
CONNECTING THE LOADS
The engine-generator covered in this manual was designed
for portable use. Do NOT operate indoors. The unit should
be stored in a warm, dry location. Move the unit outdoors
to a flat, dry location for use.
WARNING: PERSONAL DANGER:
Operating any engine driven generator without
proper air flow can result in personal injury or death.
DO NOT operate this unit inside a home or garage,
near vents or windows, or anywhere carbon monoxide
gas could accumulate.
Failure to properly limit and balance the load applied to
the generator will cause the generator to produce low
voltage and may damage the engine generator set. It may
also cause severe damage to the loads connected to the
generator at the time. Improper loading of the generator
set constitutes abuse and will not be covered by warranty.
A 30 Amp receptacle (NEMA L14-30) has been provided
to allow the connection of loads to the generator. This
receptacle is a full load receptacle protected by a 30 Amp
hydraulic magnetic breaker. The breaker toggle switch is
located on the control panel, located next to the receptacle.
Your individual loads must be protected by individual circuit
breakers mounted in some type of distribution panel. This
location will also be where you will install your neutral
to ground bond. You must wire four separate wires from
the generator (2-hot, 1- neutral, and 1-ground) to the
distribution panel.
APPLYING THE LOADS
Allow the engine to warm up for two or three minutes
before applying any load. This will allow the engine to
reach normal operating temperature and oil to circulate
throughout the engine. A short warm-up time will permit
the engine to work more efficiently when the load is
applied and will reduce the wear in the engine, extending
its life. Receptacles have been provided to allow loads to be
connected to the generator.
The loads should be added one at a time. If a large motor
is being started: or multiple motors are being started, they
should be started individually and the largest should be
started first.
CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within in the generator and
receptacle nameplate rating. Overloading may cause
damage to the generator and/or the loads.
