TP-6120 5/02 III Safety Precautions and Instructions
Hazardous Noise
Hazardous noise.
Can cause hearing loss.
Never operate the generator set
without a muffler or with a faulty
exhaust system.
CAUTION
Engine noise. Hazardous noise can
cause hearing loss.
Generator sets
not equipped with sound enclosures
can produce noise levels greater than
105 dBA. Prolonged exposure to noise
levels greater than 85 dBA can cause
permanent hearing loss. Wear hearing
protection when near an operating
generator set.
Hazardous Voltage/
Electrical Shock
Hazardous voltage.
Can cause severe injury or death.
Only authorized personnel should
open the enclosure.
(600 volts and under)
WARNING
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
Moving rotor.
WARNING
Grounding electrical equipment.
Hazardous voltage can cause
severe injury or death. Electrocution
is possible whenever electricity is
present.
Open the main circuit
breakers of all power sources before
servicing the equipment. Configure the
installation to electrically ground the
generator set and related equipment
and electrical circuits to comply with
applicable
codes and standards.
Never contact electrical leads or
appliances when standing in water or
on
wet ground because these
conditions increase the risk of
electrocution.
High voltage test. Hazardous
voltage can cause severe injury or
death.
Follow the instructions of the
test equipment manufacturer when
performing high-voltage tests on the
rotor or stator.
An improper test
procedure can damage equipment or
lead to generator set failure.
Connecting the battery and the
battery charger. Hazardous voltage
can cause severe injury or death.
Reconnect the battery correctly,
positive to positive and negative to
negative, to avoid electrical shock and
damage to the battery charger and
battery(ies).
Have a qualified
electrician install the battery(ies).
Short circuits. Hazardous
voltage/current can cause severe
injury or death.
Short circuits can
cause bodily injury and/or equipment
damage
. Do not contact electrical
connections with tools or jewelry while
making
adjustments or repairs.
Remove all jewelry before servicing the
equipment.
Testing live electrical circuits.
Hazardous voltage or current can
cause severe injury or death.
Have
trained and qualified personnel take
diagnostic
measurements of live
circuits. Use adequately rated test
equipment with electrically insulated
probes and follow the instructions of the
test equipment manufacturer when
performing voltage tests. Observe the
following precautions when performing
voltage tests: (1) Remove all jewelry.
(2) Stand on a dry, approved electrically
insulated mat. (3) Do not touch the
enclosure or components inside the
enclosure.
(4) Be prepared for the
system to operate automatically.
(600 volts and under)
Hot Parts
Hot engine and exhaust system.
Can cause severe injury or death.
Do not work on the generator set until it
cools.
WARNING
Servicing the generator. Hot parts
can cause severe injury or death.
Avoid touching the generator set field
or exciter armature. When shorted, the
generator set field and exciter armature
become hot enough to cause severe
burns.
Servicing the exhaust system. Hot
parts can cause severe injury or
death.
Do not touch hot engine parts.
The engine and exhaust system
components become extremely hot
during operation.
