7Safety Precautions and InstructionsTP-7070 8/20
Fuel tanks. Explosive fuel vapors
c
an cause severe injury or death.
Gasoline and other volatile fuels stored
in day tanks or subbase fuel tanks can
cause an explosion. Store only diesel
fuel in tanks.
Draining the fuel system. Explosive
fuel vapors can cause severe injury
or death. Spilled fuel can cause an
explosion. Use a container to catch fuel
when draining the fuel system. Wipe up
spilled fuel after draining the system.
Hazardous Noise
Hazardous noise.
C
an 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/
M
oving Parts
Hazardous voltage. Moving parts.
Will cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
DANGER
Hazardous voltage. Backfeed to
the utility system.
Can cause property damage,
severe injury, or death.
If the generator set is used for
standby power, install an automatic
transfer switch to prevent inadvertent
interconnection of standby and
normal sources of supply.
WARNING
Hazardous voltage.
Will cause severe injury or death.
Disconnect all power sources before
opening the enclosure.
DANGER
Grounding electrical equipment.
Hazardous voltage will cause severe
injury or death. Electrocution is
possible whenever electricity is
present. Ensure you comply with all
applicable codes and standards.
Electrically ground the generator set,
transfer switch, and related equipment
and electrical circuits. Turn off the main
circuit breakers of all power sources
before servicing the equipment. Never
contact electrical leads or appliances
when standing in water or on wet
ground because these conditions
increase the risk of electrocution.
Installing the battery charger.
Hazardous voltage will cause severe
injury or death. An ungrounded
battery charger may cause electrical
shock. Connect the battery charger
enclosure to the ground of a permanent
wiring system. As an alternative, install
an equipment grounding conductor
with circuit conductors and connect it to
the equipment grounding terminal or
the lead on the battery charger. Install
the battery charger as prescribed in the
equipment manual. Install the battery
charger in compliance with local codes
and ordinances.
Connecting the battery and the
battery charger. Hazardous voltage
will 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 will 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.
Engine block heater. Hazardous
voltage will cause severe injury or
death. The engine block heater can
cause electrical shock. Remove the
engine block heater plug from the
electrical outlet before working on the
block heater electrical connections.
Electrical backfeed to the utility.
Hazardous backfeed voltage can
cause severe injury or death. Install
a transfer switch in standby power
installations to prevent the connection
of standby and other sources of power.
Electrical backfeed into a utility
electrical system can cause severe
injury or death to utility personnel
working on power lines.
Testing live electrical circuits.
Hazardous voltage or current will
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.
