Grounding

Grounding Procedure for Gas Engine

To ground sprayer: Attach sprayer

grounding clamp to earth ground. Air and fluid hoses: Use only electrically

conductive hoses with a maximum of 500ft. (150 m) combined hose length to ensure grounding continuity. Check electrical resistance of hoses. If total resistance to ground exceeds 29 megaohms, replace hose immediately.

Spray gun: Ground through connection to a properly grounded fluid hose and pump.

Grounding Procedure for Electric Motor

The sprayer cord includes a grounding wire with an appropriate grounding contact.

If using the electric motor, plug must be plugged into an actual outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician.

The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding provides an escape wire for the electric current.

• To operate the EH300DI (24W965)

sprayer, the generator needs to be sized for 15 kW output (minimum).

Extension Cords

Use an extension cord with an undamaged ground contact. If an extension cord is necessary, use a 3-wire, 12 AWG (2.5 mm²) minimum.

NOTE: Smaller gauge or longer extension cords may reduce sprayer performance.

Grounding of Pails

Solvent pails used when flushing: Follow

local code. 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.

Always ground a metal pail: connect a ground wire to the pail. Clamp one end to the pail and the other end to a true earth ground such as a water pipe.

To maintain ground continuity when sprayer is flushed or pressure is relieved:

hold metal part of spray gun firmly to the side of a grounded metal pail then trigger the gun.

Circuit Protection

Connect sprayers only to circuits which have the properly sized circuit breaker and/or fuses (for unit power requirements see Technical Data,
