Grounding
The following are minimum grounding requirements for
a basic electrostatic system. Your system may include
other equipment or objects which must be grounded.
Check your local electrical code for detailed grounding
instructions. Your system must be connected to a true
earth ground.
• Pump: ground the pump by connecting a ground
wire and clamp as described in your separate pump
instruction manual.
• Electrostatic Air-Assisted Spray Gun: ground the
gun by connecting the Graco Grounded Air Hose to
the turbine air inlet and connecting the air hose
ground wire to a true earth ground. See Check
Electrical Grounding, page 16.
• Air compressors and hydraulic power supplies:
ground the equipment according to the manufac-
turer's recommendations.
• All air and fluid lines must be properly grounded.
• All electrical cables must be properly grounded.
• All persons entering the spray area: shoes must
have conductive soles, such as leather, or personal
grounding straps must be worn. Do not wear shoes
with non-conductive soles such as rubber or plastic.
• Object being sprayed: keep the workpiece hangers
clean and grounded at all times. Resistance must
not exceed 1 megohm.
• The floor of the spray area: must be electrically con-
ductive and grounded. Do not cover the floor with
cardboard or any non-conductive material which
would interrupt grounding continuity.
• Flammable liquids in the spray area: must be kept in
approved, grounded containers. Do not use plastic
containers. Do not store more than the quantity
needed for one shift.
• All electrically conductive objects or devices in the
spray area: including fluid containers and wash
cans, must be properly grounded.
WARNING
Fire, Explosion, and Electric Shock Hazard
When operating the electrostatic gun, any
ungrounded objects in the spray area (peo-
ple, containers, tools, etc.) can become
electrically charged. Improper grounding
can result in static sparking, which can
cause a fire, explosion, or electric shock.
Follow the grounding instructions below.
