Warnings

4 308778U

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-

tion point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When

these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and

warnings not covered in this section may appear throughout the body of this manual where applicable.

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent

fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop

cloths (potential static arc).

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes

are present.

• Ground all equipment in the work area. See Grounding instructions.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they

are antistatic or conductive.

• Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment

until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

INTRINSIC SAFETY

Intrinsically safe equipment that is installed improperly or connected to non-intrinsically safe equipment

will create a hazardous condition and can cause fire, explosion, or electric shock. Follow local regula-

tions and the following safety requirements.

• Be sure your installation complies with national, state, and local codes for the installation of electrical

apparatus in a Class I, Group D, Division 1 Hazardous Location, including all of the local safety fire

codes, NFPA 33, NEC 500 and 516, and OSHA 1910.107.

• Equipment that comes in contact with the safety barrier’s intrinsically safe terminals must be rated

for Intrinsic Safety. This includes DC voltage meters, ohmmeters, cables, and connections. Remove

the unit from the hazardous area when troubleshooting.

• If a printer, computer, or other electrical component is connected, it must be used in conjunction with

a safety barrier.

• Without the safety barrier, the equipment is no longer intrinsically safe and must not be operated in

hazardous locations, as defined in article 500 of the National Electrical Code (USA) or your local

electrical code.

• Do not install equipment approved only for a non-hazardous location in a hazardous area. See the

ID label for the intrinsic safety rating for the flow meter sensor.

• Ground the intrinsically safe power supply. A voltage limiting safety barrier must be properly

grounded to be effective. For proper grounding, use the ground wire provided (or a 12 gauge mini-

mum ground wire), and the barrier’s ground must be within 1 ohm of true earth ground.

• Do not operate the safety barrier module with the cover removed.

• Never use the flow meter with an electrostatic gun isolation stand.
