8 Safety Precautions and Instructions
TP-6197 3/06
Disconnecting the electrical load.
Hazardous voltage can cause
severe injury or death. Disconnect
the generator set from the load by
turning off the line circuit breaker or by
disconnecting the generator set output
leads from the transfer switch and
heavily taping the ends of the leads.
High voltage transferred to the load
during testing may cause personal
injury and equipment damage. Do not
use the safeguard circuit breaker in
place of the line circuit breaker. The
safeguard circuit breaker does not
disconnect the generator set from t he
load.
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 ground connection
close to the weld location.
Installing the battery charger.
Hazardous voltage can cause
severe injury or death. An
ungrounded battery charger may
cause electrical shock. Connect the
battery charger enclosure to theground
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
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.
Engine block heater. Hazardous
voltage can 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.
Airborne particles.
Can cause severe injury or
blindness.
Wear protective goggles and clothing
when using power tools, hand tools,
or compressed air.
WARNING
Servicing the generator set when it
is operating. Exposed moving parts
can cause severe i njury or death.
Keep hands, feet, hair, clothing, and
test leads away from the belts and
pulleys when the generator set is
running. Replace guards, screens, and
covers before operating the generator
set.
Heavy Equipment
Unbalanced weight.
Improper lifting can cause severe
injury or death and equipment
damage.
Do not use lifting eyes.
Lift the generator set using lifting bars
inserted through the lifting holes on
the skid.
WARNING
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 work on the generator 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.
