TP-6905 6/148 Safety Precautions and Instructions
Welding on the generator set. Can
cause severe electrical equipment
damage. Before welding on the
generator set perform the following
steps: (1) Remove the battery cables,
negative (--) lead first. (2) Disconnect
all engine electronic control module
(ECM) connectors. (3) Disconnect all
generator set controller and voltage
regulator circuit board connectors.
(4) Disconnect the engine battery-
charging alternator connections.
(5) Attach the weld g round connection
close to the weld location.
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 servicingthe
equipment.
Engine oil pan heater. Hazardous
voltage can cause severe injury or
death. The engine oil pan heater can
cause electrical shock. Disconnect
power to the engine oil pan heater and
allow to cool before working on the oil
pan 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.
Servicing the generator set when it
is operating. Exposed moving parts
can cause severe injury or death.
Keep hands, feet, hair, clothing, and
test leads away from the belts and
pulleys when the generator set is
running. Replaceguards, screens, and
covers before operating the generator
set.
Hot Parts
Hot coolant and steam.
Can cause severe injury or death.
Before removing the pressure cap,
stop the generator set and allow it to
cool. Then loosen the pressure cap
to relieve pressure.
WARNING
Hot engine and exhaust system.
Can cause severe injury or death.
Do not workon thegenerator set until
it cools.
WARNING
Servicing the alternator. Hot parts
can cause severe injury or death.
Avoid touching the alternator field or
exciter armature. When shorted, the
alternator 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.
Servicing the engine oil pan heater.
Heated components can cause
severe injury. The oil pan heater will
rapidly become hot when energized.

hot. Disconnect power to the engine oil
pan heater and allow to cool before
servicing it or nearby parts.
Notice
NOTICE
Canadian installations only.For
standby service connect the output of
the generator set to a suitably rated
transfer switch in accordance with
Canadian Electrical Code, Part 1.
NOTICE
Electrostatic discharge damage.
Electrostatic discharge (ESD)
damages electronic circuit boards.
Prevent electrostatic discharge
damage by wearing an approved
grounding wrist strap when handling
electronic circuit boards or integrated
circuits. An approved grounding wrist
strap provides a high resistance (about
1 megohm), not a direct short,to
ground.
