Grounding

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.

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.

FIG. 8. Ground Screw and Power Switch

Gun Flush Box

Connect a ground wire from the Gun Flush Box ground lug to a true earth ground.

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.

Installation

Air and Fluid Hoses

Use grounded hoses only.

Spray Gun

Follow the grounding instructions in your gun manual.

•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

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