TP-6391 9/08 7Safety Precautions and Instructions
Grounding electrical equipment.
Hazardous voltage can 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 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 t o 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 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.
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 can
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, approvedelectrically
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
Notice
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 f rom metal
surfaces.
