Grounding - Graco QUANTM i30 Instructions Manual

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.
• Always ground the entire fluid system as
described in this section.
• Follow local codes and regulations.
Before operating the equipment, ground the system as
follows.
Ground the Pump
Connect a Static Ground
See F . 7.
IG
1. Loosen the ground fastener (E).
2. Insert one end of a 12-gauge or thicker ground wire
behind the ground fastener and securely tighten the
ground fastener (E).
3. Connect the clamp end of the ground wire to a true
earth ground.
NOTE: A ground wire and clamp (part number 238909)
is available (purchase separately).

Connect the Electrical Ground
For Models in Explosive Atmospheres or Hazardous
(Classified) Locations): Ground through the ground
wire of the power cable to a true earth ground. Connect
the ground wire of the power cable to a true earth
ground. See Electrical Connections and Wiring,
starting on page 17.
For Models in Ordinary Locations: Ground through
the provided power cord and plug. Connect the plug to
a power outlet that is properly installed and grounded
to a true earth ground.
Ground the Fluid Lines
Use only conductive fluid lines with a maximum of 500
ft (150 m) combined line length to ensure grounding
continuity. Check electrical resistance of the fluid lines.
Ground the Fluid Supply Container
Follow local codes and regulations.
Ground the Pails for Solvents and
Sanitizing Solution Used when Flushing
Follow local codes and regulations. 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.
Verify Ground Continuity
Check the pump ground continuity after the initial
installation. Set a regular schedule for checking ground
continuity to maintain proper grounding. Do not exceed
1 ohm resistance from earth ground to the pump.
