Graco 3A0869H Grounding, Check Resistance

Installation

3A0869H 21

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.
