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.
