2. If the generator set is connected to an existing distribution system,
a fully isolated manual transfer switch must be installed. The transfer
switch prevents damage to the generator and the other circuit
components if main line power is restored while the generator is
connected. This generator is GFCI protected, so the transfer switch
needs to be GFCI compatible. If the transfer switch is not GFCI
compatible, the breaker on the generator will always trip.
3. Many homes and construction sites are wired for at least 60 to 100
Amp entrance service, much greater than the capacity of this portable
generator. When installing the generator at these sites, a secondary
emergency distribution panel may have to be installed. The emergency
distribution panel must be installed by a licensed electrician according
to all applicable codes. The electrician will move the critical circuits to
be powered during the outage to the emergency panel. Keep in mind
only a limited amount of amperage is available from the generator set.
Some circuit breakers may still have to be turned off to prevent an
overload on the generator during the initial start up. See the nameplate
on your generator for the amperage capabilities of your unit.
CAUTION: EQUIPMENT DAMAGE
Failure to properly limit and balance the load a[[lied 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 that time. Improper loading of the
generator set constitutes abuse and will not be covered by warranty.
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
All units must be grounded. Drive a 3/4 or 1” copper pipe or rod into
the ground close to the engine-generator set. The pipe must penetrate
moist earth. Connect an approved ground clamp to the pipe. Run a
no. 10 Awg wire from the clamp to the generator ground lug on the
receptacle panel. Do not connect to a water pipe or to a ground used
by a radio system. The engine-generators covered in this manual were
designed primarily for portable use. If you are connecting into a building
wiring system that is already grounded using the 14-30 4 wire plug, you
do not have to ground the unit.
WARNING: PERSONAL DANGER
DO NOT OPERATE THIS GENERATOR INDOORS, The unit should
be stored in a warm, dry location. During a power outage, move the
unit outdoors to a at, dry location such as a driveway or sidewalk.
WIRING
Plug your tools such as drills, saws, blowers, sump pump, and other
items to be powered directly into the generator receptacles. Before
plugging in all the tools and cord sets, recheck the rating of the
generator set. Be sure it can handle the intended load and is
compatible with the voltage, phase, and current ratings. ‘Hard wiring’
this unit directly into a temporary construction site electrical system is
NOT A SIMPLE DO-IT-YOURSELF JOB. For your safety, all wiring
must be done by a qualied electrician and conform to the National
Electric Code and comply with all state/local codes and regulations.
Check with local authorities before proceeding.
WARNING: PERSONAL DANGER
A fully isolated, double pole double throw manual transfer switch must
be installed any time a generator is being connected to an existing
distribution system.
1. These engine-generator sets are designed for portable heavy duty
commercial use. Receptacles are provided on the control panel to
permit 120 and 240 Volt portable appliances and tools to be plugged
directly into them. Please note that the 3-wire 240 Volt receptacle(s) on
these units are designed to power only 240 Volt tools. There are two
hot leads and a ground wire, but no neutral connection, in the 3-wire
240Volt receptacle. A 4-wire receptacle (two hot, one ground, and one
neutral) has been provided on the control panel for use in temporary
power applications requiring 120/240 Volt power. Consult a licensed
electrician for wiring the TemPower plug and connecting it as temporary
service.
To connect these units directly to an un-powered, isolated construction
site TemPower panel, have your electrician connect to the control panel
using a 120/240 Volt, 4-wire twist-lock plug (L14-30P).
YOURGEN
The WINCO YourGen meter allows you to see useful information about
your generator from the front panel by displaying RPMs, Voltage,
frequency, load, hours, and maintenance reminders. It also has the
ability to display warnings if any parameter gets outside of normal
operation range.
Cycle Button ( ) -
During normal operation, the display will toggle through on xed delay.
If you want to see any specic item, you can press the cycle button to
move it to that setting. Once the display is selected, the delay before it
starts toggling is approximately 5 seconds. This button is also used to
reset maintenance reminders.
RPM -
The meter will display the RPMs of the engine. This number is
calculated based upon frequency and is not directly measured from the
engine. The engine-generator must be run at the correct speed in order
to produce the proper electrical voltage and frequency.
CAUTION: EQUIPMENT DAMAGE
The output voltage should be checked to ensure the generator is
working properly prior to connecting a load to the generator. Failure to
do so could result in damage to equipment plugged into the unit and
possible injury to the individual.
