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, Division 1, Group D 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.
• The equipment in the hazardous area is intrinsically safe or explosion proof when no external electri-
cal components are connected to it. If any 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 the Main Control Panel, which is not intrinsically safe, in a hazardous area, as defined
in Article 500 of the National Electrical Code (USA) or your local electrical code.
• 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.
SKIN INJECTION HAZARD
High-pressure fluid from dispense device, hose leaks, or ruptured components will pierce skin. This may
look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treat-
ment.
• Do not point dispense device at anyone or at any part of the body.
• Do not put your hand over the dispense outlet.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow Pressure Relief Procedure in this manual, when you stop dispensing and before cleaning,
checking, or servicing equipment.
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids
containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical
reaction and equipment rupture, and result in death, serious injury, and property damage.
