1.0 WARNINGS AND CAUTIONS
Four commonly used safety symbols accompany the DANGER, WARNING, and CAUTION
blocks. The type of informaon each indicates is as follows:
This General warning symbol points out important safety
informaon that, if not followed, could endanger personal safety
and/or property of others.
This Explosion warning symbol points out potenal explosion
hazard(s).
This Fire warning symbol points out potenal re hazard(s).
This Electrical warning symbol points out potenal electrical
shock hazard(s).
Improper operaon of this equipment such as neglecng its maintenance or
being careless can cause possible injury or death. Permit only responsible and
capable persons to install, operate, and/or maintain this equipment.
Potenally lethal voltages and amperages are present in these machines. Ensure
all steps are taken to render the machine safe before aempng to work on the
equipment.
ELECTRICAL WARNING
• All hardware covered by this manual have dangerous electrical voltages and can
cause fatal electrical shock. Avoid contact with bare wires, terminals, connecons,
etc., on the hardware, if applicable. Ensure all appropriate covers, guards, grounds,
and barriers are in place before operang the equipment. If work must be done
around an operang unit, stand on an insulated dry surface to reduce shock hazard.
• Do not handle any kind of electrical device while standing in water, while barefoot, or
while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.
• If trained personnel must stand on metal or concrete while installing, servicing,
adjusng, or repairing this equipment, place insulave mats over a dry wooden
plaorm. Work on the equipment only while standing on such insulave mats.
• The Naonal Electrical Code (NEC), Arcle 250 requires the frame of the equipment
to be connected to an approved earth ground and/or grounding rods. This grounding
will help prevent dangerous electrical shock that might be caused by a ground fault
condion or by stac electricity. Never disconnect the ground wire.
• Wire gauge sizes of electrical wiring, cables, and cord sets must be adequate to
handle the maximum electrical current (ampacity) to which they will be subjected.
