Grounding the System
3A4100D 7
Grounding the System
Pump: Use a ground wire and clamp (supplied). Verify
that the ground screw (GG) is attached and tightened
securely to the air motor. Connect the clamp (U) of the
static ground cable (HH) to a true earth ground. For a
replacement ground wire and clamp, order part 244524.
NOTE: Have qualified personnel check the resistance
between each pump and the true earth ground.
Air and fluid hoses: Use only electrically conductive
hoses with a maximum of 500 ft (150 m) combined hose
length to ensure grounding continuity. Check electrical
resistance of hoses. If total resistance to ground
exceeds 29 megohms, replace the hose immediately.
Air compressor: Follow manufacturer recommendations.
Spray gun or dispensing valve: Ground through connec-
tion to a properly grounded fluid hose and pump.
NOTE: See system manual for additional grounding
information.
NOTE: Use a meter that is capable of measuring resis-
tance at this level.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes
to ignite or explode. Grounding provides an escape
wire for the electric current.
