Operation
Adequate, unobstructed flow of cooling and
ventilating air is critical to correct generator
operation. Do not alter the installation or permit
even partial blockage of ventilation provisions,
as this can seriously affect safe operation
of the generator. The generator MUST be
operated outdoors.
This exhaust system must be properly
maintained. Do nothing that might render the
exhaust system unsafe or in noncompliance
with any local codes and/or standards.
Always use a battery operated carbon
monoxide alarm indoors, installed according to
the manufacturers instructions.
2.6.1 SYSTEM GROUND
The generator has a system ground that connects the generator
frame components to the ground terminals on the AC output
receptacles. The system ground is bonded to the AC neutral wire
in the generator control panel via a jumper wire.
Special Requirements
There may be Federal or State Occupational Safety and Health
Administration (OSHA) regulations, local codes, or ordinances that
apply to the intended use of the generator.
Please consult a qualified electrician, electrical inspector, or the
local agency having jurisdiction:
•
In some areas, generators are required to be registered with
local utility companies.
•
If the generator is used at a construction site, there may be
additional regulations which must be observed.
Connecting to a Building's Electrical System
Connections for standby power to a building's electrical system
must be made by a qualified electrician. The connection must
isolate the generator power from utility power or other alternative
power sources and must comply with all related laws and codes.

2.6.2 GROUNDING THE GENERATOR
The National Electrical Code requires that the frame and
external electrically conductive parts of this generator be
properly connected to an approved earth ground (Figure 9).
Local electrical codes may also require proper grounding of the
unit. For that purpose, connecting a No. 10 AWG (American Wire
Gauge) stranded copper wire to the grounding lug and to an
earth-driven copper or brass grounding rod (electrode) provides
adequate protection against electrical shock. However, local codes
may vary widely. Consult with a local electrician for grounding
requirements in the area.
Figure 9 - Grounding the Generator
Proper grounding of the generator will help prevent electrical
shock in the event of a ground fault condition in the generator
or in connected electrical devices. Proper grounding also helps
dissipate static electricity, which often builds up in ungrounded
devices.
2.6.3 CONNECTING ELECTRICAL LOADS
DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT
connect 3-phase loads to the generator. DO NOT connect 50 Hz
loads to the generator.
•
Let engine stabilize and warm up for a few minutes after
starting.
•
Plug in and turn on the desired 120 or 240 Volt AC, single
phase, 60 Hz electrical loads.
•
Add up the rated watts (or amps) of all loads to be connected
at one time. This total should not be greater than (a) the rated
wattage/amperage capacity of the generator or (b) circuit
breaker rating of the receptacle supplying the power. See "Don't
Overload the Generator".
2.7 OVERLOAD PREVENTION
Overloading a generator in excess of its rated wattage capacity
can result in damage to the generator and to connected electrical
devices. Observe the following to prevent overloading the unit:
•
Add up the total wattage of all electrical devices to be connected
at one time. This total should NOT be greater than the
generator's wattage capacity.
•
The rated wattage of lights can be taken from light bulbs. The
rated wattage of tools, appliances and motors can usually be
found on a data label or decal affixed to the device.
