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.
PSM Machine (H, page 7): grounded through the PSM
Installation Plate (AC, page 8). Use the supplied ground
wire and clamp to ground the metal PSM Installation
Plate (AC, page 8) or Customer Robot (G, page 7) to a
true earth ground.

PSM Control Box (F, page 7): grounded through the
power cord.
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 hose
immediately.
Air compressor: follow manufacturer's
recommendations.
Dispense Valve (AB, page 8): ground through
connection to a properly grounded fluid hose and
pump.
Fluid supply container: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a non-conductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
