ELECTRICAL HAZARDS
This product must be grounded. If it should malfunction or breakdown,
grounding provides a path of least resistance for electric current to
reduce the risk of electric shock. Do not touch live electrical parts.
DANGER - IMPROPER CONNECTION OF THE EQUIPMENT-
GROUNDING CONDUCTOR CAN RESULT IN A RISK OF
ELECTROCUTION. CHECK WITH A QUALIFIED ELECTRI-
CIAN OR SERVICE PERSON IF YOU ARE INDOUBT AS TO
WHETHER THE UNIT IS PROPERLY GROUNDED.
This unit is equipped with a grounding terminal for your protection.
Always complete the ground path from the unit to an external ground
source as instructed in the section labeled “Grounding Instructions” in
the Preparation section of this manual.
The unit is a potential source of electrical shock if not kept dry. Keep
the unit dry and do not use in rain or wet conditions. To protect from
moisture, operate it on a dry surface under an open, canopy-like
structure. Dry your hands if wet before touching the unit.
Plug appliances directly into the unit. Or, use a heavy duty, outdoor-
rated extension cord that is rated (in watts or amps) at least equal to
the sum of the connected appliance loads. Check that the entire cord
is free of cuts or tears and that the plug has all three prongs, especially
a grounding pin.
NEVER try to power the house wiring by plugging the unit into a
wall outlet, a practice known as “back feeding”. This is an extremely
dangerous practice that presents an electrocution risk to utility workers
and neighbors served by the same utility transformer. It also bypasses
some of the built-in household circuit protection devices.
If you must connect the unit to the house wiring to power appliances,
have a qualified electrician install the appropriate equipment in
accordance with local electrical codes. Or, check with your utility
company to see if it can install an appropriate power transfer switch.
For power outages, permanently installed stationary units are better
suited for providing backup power to the home. Even a properly
connected portable unit can become overloaded. This may result in
overheating or stressing the unit components, possibly leading to a
unit failure.
Do not use worn, damaged, undersized, or poorly spliced welding
cables. Do not drape welding cables over your body. Do not touch
electrode if you are in contact with the work, ground, or another
electrode from a different machine.
