Grounding

Grounding Grounding
The equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Ground all equipment, personnel, objects
being sprayed, and conductive objects in or close
to the spray area. The resistance must not exceed
100 ohms. Grounding provides an escape wire for
the electric current.
When operating the electrostatic gun, any
ungrounded objects (such as people, containers, and
tools) in the spray location can become electrically
charged.
The following are minimum grounding requirements
for a basic electrostatic waterborne system. Your
system may include other equipment or objects
which must be grounded. Your system must be
connected to a true earth ground. Check ground
connections daily. Check your local electrical codes
and regulations for detailed grounding instructions.
• All persons entering the spray area:
shoes having conductive soles such as leather,
or wear personal grounding straps. Do not
wear shoes with non-conductive soles such as
rubber or plastic. If gloves are necessary, wear
the conductive gloves supplied with the gun. If
non-Graco gloves are worn, cut off fingers or palm
area of gloves to ensure your hand contacts the
grounded gun handle.
Object being sprayed:
•
clean and grounded at all times.

must be properly grounded.
Fluid and waste containers:
•
waste containers in the spray area. Do not use pail
liners unless they are conductive and grounded.
When flushing the spray gun, the container used
to catch the excess fluid must be electrically
conductive and grounded.
Air compressors:
• Ground the equipment according
to the manufacturer's recommendations.
• All air lines must be properly grounded. Use only
grounded hoses with a maximum of 100 feet (30.5
m) combined hose length to ensure grounding
continuity.
