Grounding
This 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.
1. Pump: The pump is grounded through
a proper electrical connection. See
Main Power Connections at the VFD, page 14.
2. Fluid hoses: Use only electrically conductive
hoses with a maximum of 500 ft. (150 m)
combined hose length to ensure grounding
continuity. Check the electrical resistance of
hoses. If total resistance to ground exceeds 25
megohms, replace hose immediately.
3. Fluid supply container: Follow your local code.
4. All solvent p
ails used when flushing: Follow local
code. Use onl
y metal pails, which are conductive.
Do not place
the pail on a non-conductive
surface, su
ch as paper or cardboard, which
interrupts
the grounding continuity.
5. To maintain grounding continuity when flushing
or relieving pressure: Always hold the metal
nozzle firmly to the side of a grounded metal pail.
