TP-6071 3/00 IV Safety Precautions and Instructions
Engine noise. Hazardous noise can
cause hearing loss.
Generator sets
not equipped with sound enclosures
can produce noise levels greater than
105 dBA. Prolonged exposure to noise
levels greater than 85 dBA can cause
permanent hearing loss. Wear hearing
protection when near an operating
generator set.
Hazardous Voltage
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
Moving rotor.
WARNING
Grounding electrical equipment.
Hazardous voltage can cause
severe injury or death. Electrocution
is possible whenever electricity is
present.
Open the main circuit
breakers of all power sources before
servicing the equipment. Configure the
installation to electrically ground the
generator set, transfer switch, and
related
equipment and electrical
circuits to comply with applicable codes
and
standards. 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
opening 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 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 wristwatch, rings, and 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
t
, PowerBoost
t
III, and
PowerBoost
t
V voltage regulator
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
opened.
Backfeed connections can
cause serious 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 rings,
wristwatch, and 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)
Heavy Equipment
Unbalanced weight.
Improper lifting can cause severe
injury or death and equipment
damage.
Do not use lifting eyes.
Use slings under the skid to balance
and lift the generator set.
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.
