TP-7045 3/18c 7 Safety Precautions and Instructions
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.
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.
Testing the voltage regulator.
Hazardous voltage can cause
severe injury or death. High voltage
is present at the voltage regulator heat
sink. To prevent electrical shock do not
touch the voltage regulator heat sink
when testing the voltage regulator.
(PowerBoost

models only)
Electrical backfeed to the utility.
Hazardous backfeed voltage can
cause severe injury or death.
Connect the generator set to the
building/marina electrical system only
through an approved device and after
the building/marina main switch is
turned off. Backfeed connections can
cause severe injury or death to utility
personnel working on power lines
and/or personnel near the work area.
Some states and localities prohibit
unauthorized connection to the utility
electrical system. Install a
ship-to-shore transfer switch to prevent
interconnection of the generator set
power and shore power.
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)
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 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.
Notice
NOTICE
This generator set has been
rewired from its nameplate voltage
to
246242
NOTICE
Voltage reconnection. Affix a notice
to the generator set after reconnecting
the set to a voltage different from the
voltage on the nameplate. Order
voltage reconnection decal 246242
from an authorized service
distributor/dealer.
NOTICE
Fuse replacement. Replace fuses
with fuses of the same ampere rating
and type (for example: 3AB or 314,
ceramic). Do not substitute clear
glass-type fuses for ceramic fuses.
Refer to the wiring diagram when the
ampere rating is unknown or
questionable.
NOTICE
Saltwater damage. Saltwater quickly
deteriorates metals. Wipe up saltwater
on and around the generator set and
remove salt deposits from metal
surfaces.
