Hazardous Voltage/Moving Parts
DANGER
DANGER
WARNING
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.
High voltage test. Hazardous voltage will 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 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. (600 volts and under)
TP-7173 10/20
Hazardous voltage.
Will cause severe injury or death.
Disconnect all power sources before opening the enclosure.
Hazardous voltage. Moving parts.
Will cause severe injury or death.
Operate the generator set only when all guards and electrical enclosures are in place.
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.
