Grounding - Graco XP-H Series Operation, Repair, And Parts

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.
Grounding provides an escape wire for the electric
current.
Pump: Use the ground wire and clamp (supplied).
XP Units
Connect ground clamp to a true earth ground.
XP-h Units
Loosen grounding lug locknut (GW) and washer
(GX). Insert ground wire end (Z) into lug (GY) slot
and tighten locknut securely. Connect ground
clamp to a true earth ground.

Object being sprayed: Ground the object being
sprayed, fluid supply container, and all other equipment
in the work area. Follow your local code. Use only
electrically conductive air and fluid hoses.
Solvent pails: Use only metal pails, which are
conductive, placed on a grounded surface. Do not place
pail on a non-conductive surface, such as paper or
cardboard, which interrupts grounding continuity.
Solvent Pump: use ground wire and clamp (supplied
with solvent pump).
Air and fluid hoses: use only static dissipation type
hoses with a maximum of 300 ft (91 m) combined hose
length to ensure grounding continuity. Check electrical
resistance of hoses regularly. If total resistance to ground
exceeds 29 megohms, replace hose immediately.
Air compressor: follow manufacturer's
recommendations.
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
System: connect the supply ground wire in the electrical
compartment as shown in Connect Power on page 24.
