Grounding
Connect the ProMix 2KE ground wire to the ground
screw. Connect the clamp to a true earth ground. If wall
power is used to power controls, ground electrical con-
nection according to local codes.
Gun Flush Box
Connect a ground wire from the Gun Flush Box ground
lug to a true earth ground.
Flow Meters
Verify that the meter cables are connected as shown in
the Hazardous Location Electrical Schematic on
page 74-75. Failure to properly connect the shield may
cause incorrect signals.
NOTE: The Coriolis meter can be used only on non-IS
systems 24F080-24F083. When installed on these sys-
tems, the meter’s hazardous location intrinsically safe
status is voided.
Feed Pumps or Pressure Pots
Connect a ground wire and clamp from a true earth
ground to the pumps or pots. See pump or pressure pot
manual.
Air and Fluid Hoses
Use grounded hoses only.
Spray Gun
• Non-Electrostatic: Ground the spray gun through
connection to a Graco-approved grounded fluid sup-
ply hose.
• Electrostatic: Ground the spray gun through con-
nection to a Graco-approved grounded air supply
hose. Connect the air hose ground wire to a true
earth ground.
Fluid Supply Container
Follow local code.
Object Being Sprayed
Follow local code.
All Solvent Pails Used When Purging
Follow local code. Use only conductive metal pails/con-
tainers placed on a grounded surface. Do not place the
pail/container on a nonconductive surface, such as
paper or cardboard, which interrupts the grounding con-
tinuity.
Check Resistance
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical current
due to static build up or in the event of a short circuit.

To ensure proper grounding, resistance between
components and true earth ground must be less than
1 ohm.
