Safety Warnings and Cautions
WARNING
ELECTRIC SHOCK can KILL . Do not touch live electrical parts.
ELECTRIC ARC FLASH can injure eyes, burn skin, cause equipment damage, and
ignite combustible material. DO NOT use power cables to break load and prevent tools
from causing short circuits.
IMPROPER PHASE CONNECTION, PARALLELING, OR USE can damage this and
attached equipment.
IMPORTANT
Protect all operating personnel. Read, understand, and follow all instructions in the
Operating/Instruction Manual before installing, operating, or servicing the equipment.
Keep the manual available for future use by all operators.
WARNING
CALIFORNIA PROPOSITION 65 - DIESEL ENGINES. Diesel engine exhaust and
some of its constituents are known to the State of California to cause cancer, birth
defects and other reproductive harm.
1) General
Equipment that supplies electrical power can cause serious injury or death, or damage to other equipment or
property. The operator must strictly observe all safety rules and take precautionary actions. Safe practices
have been developed from past experience in the use of power source equipment. While certain practices
below apply only to electrically-powered equipment, other practices apply to engine-driven equipment, and
some practices to both.
2) Shock Prevention
Bare conductors, terminals in the output circuit, or ungrounded, electrically live equipment can fatally shock a
person. Have a certified electrician verify that the equipment is adequately grounded and learn what
terminals and parts are electrically
HOT . Avoid hot spots on machine. Use proper safety clothing, procedures,
and test equipment.
The electrical resistance of the body is decreased when wet, permitting dangerous currents to flow through it.
When inspecting or servicing equipment, do not work in damp areas. Stand on a dry rubber mat or dry wood,
and use insulating gloves when dampness or sweat cannot be avoided. Keep clothing dry, and never work
alone.
a) Installation and Grounding of Electrically Powered Equipment
Equipment driven by electric motors (rather than by diesel or gasoline engines) must be installed and
maintained in accordance with the National Electrical Code, ANSI/NFPA 70, or other applicable
codes. A power disconnect switch or circuit breaker must be located at the equipment. Check the
nameplate for voltage, frequency, and phase requirements. If only 3-phase power is available,
connect any single-phase rated equipment to only two wires of the 3-phase line.
DO NOT CONNECT
the equipment grounding conductor (lead) to the third live wire of the 3-phase line, as this makes the
equipment frame electrically
HOT , which can cause a fatal shock.
