Grounding

See illustration on next page.

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.

Electrical Control Box

The electrical control box has two ground points. Both connections must be made.

•Connect the ground wire (Y) to the ground screw on the electrical control box. Connect the clamp end to a true earth ground.

•The power supply must be grounded according to local codes. Connect the power supply ground wire to the Ground terminal in the electrical control box. See Electrical Connections, page 25.

Fluid Supply Container

Follow local code.

Color Change Module

Connect a ground wire from the color change module to a true earth ground.

Intrinsically safe color change modules located in the hazardous area must be connected to a true earth ground in the hazardous area.

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.
