Hazardous Voltage/Moving Parts
DANGER
DANGER
WARNING
Welding the generator set.
Can cause severe electrical equipment damage.
Welding on generator set will cause serious damage to engine electronic controls components. Disconnect all engine electronic
control connections before welding.
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.
Disconnecting the electrical load. Hazardous voltage will 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 the 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 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).
TP-7203 4/23
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.
