Ground The System - Graco PRO AA5500SC Instruction Manual

Ground the System

WARNING
FIRE, EXPLOSION, AND
ELECTRIC SHOCK HAZARD
When operating the electrostatic gun,
any ungrounded objects in the spray
area (such as people, containers, tools,
etc.) can become electrically charged.
Improper grounding can result in static
sparking, which can cause a fire, explo-
sion, or electric shock. Follow the
grounding instructions below.
The following grounding instructions are minimum
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.
1. Pump: ground the pump by connecting a ground
wire and clamp as described in your separate
pump instruction manual.
2. Air compressors and hydraulic power supplies:
ground the equipment according to the manufac-
turer's recommendations.
Installation
3. Electrostatic Air Spray Gun: ground the gun by
connecting the Graco Electrically Conductive Air
Hose to the turbine air inlet and connecting the air
hose ground wire to a true earth ground. Check
the electrical grounding of the gun as instructed on
page 14.
4. All air and fluid lines must be properly grounded.
5. All electric cables must be properly grounded.
6. All persons entering the spray area: their shoes
must have conductive soles, such as leather, or
personal grounding straps must be worn. Rubber
or plastic soles are not conductive.
7. Object being sprayed: keep the workpiece hangers
clean and grounded at all times. Contact points
must be sharp points or knife edges.
8. The floor of the spray area: must be electrically
conductive and grounded. Do not cover the floor
with cardboard or any non-conductive material
which would interrupt grounding continuity.
9. Flammable liquids in the spray area: must be kept
in approved, grounded containers. Do not store
more than the quantity needed for one shift.
10. All electrically conductive objects or devices in the
spray area: including fluid containers and wash
cans, must be properly grounded.
