CHAPTER 17
GENERATOR SET INSTALLATION PRACTICES
Section I. SAFETY PRECAUTIONS
17-1
GENERAL.
This
chapter
provides
safety
precautions, site selections guidelines, air, cooling, fuel,
exhaust, electrical, and service requirements relevant to
the proper installation of the generator set. All other
input requirements not covered in this chapter and
required by the user are the responsibility of the
cognizant installation manager.
17-2. Do not use a lifting device with a marginal
capacity when lifting and moving the generator set.
Observe the center of gravity of the equipment to be
lifted and do not allow the generator set to swing while it
is suspended. Make certain the structure to support the
generator set is strong enough to support the weight of
the set. Failure to observe this warning may result in
serious injury or death to personnel.
17-3. The voltage produced by generators is dangerous
to personnel coming in contact with any part of the
electrical system during operation. Severe, possible
fatal shock may result. See that adequate grounding
provisions have been made and the generator sets are
grounded using the ground studs provided before
operation. Be extremely careful when unit or
surrounding area is damp or wet.
17-4. In case of an accident from electrical shock, shut
down the set at once. If the set cannot be shut down,
free the victim from contact with a nonconductor, and
avoid direct contact with victim. Use a dry rope, dry
board, or any nonconducting implement to free the
victim. If the victim is unconscious, apply artificial
respiration and get medical help.
17-5. When servicing any part of the electrical system
or making any connections, be sure the maintenance
switch is in the MAINTENANCE position and padlocked.
Clean or service the generator set only when the engine
is shut down.
17-6. If the unit stops by operation of the safety
devices, do not attempt to operate it until the cause has
been eliminate.
17-7. When filling the fuel tank, do not smoke or use
open flame in the vicinity. Be extremely careful when
using a carbon tetrachloride fire extinguisher in an
enclosed area. A poisonous gas is generated by the
contact of carbon tetrachloride with heated surfaces.
Provide
adequate
ventilation
before
entering
an
enclosed area where carbon tetrachloride has been
used.
17-8. When operating in an enclosed area, pipe the
engine exhaust outside. Be sure to increase the pipe
diameter and use a minimum amount of bends and
elbows to prevent back pressure in the engine exhaust
system. Be sure the enclosure has proper ventilation to
accommodate the engine cooling system.
17-9. When servicing batteries, do not smoke or use an
open flame in the vicinity. Batteries generate explosive
gas during charging.
7-10. DANGER signs must be placed in the vicinity of
the engine. There is to be no smoking in the vicinity.
No work is to be performed on the engine involving
open flames, such as cutting, welding, grinding,
chiseling, or any similar operation which may produce
sparks.
17-11. A fire extinguisher (dry powder or carbon
dioxide, CO2) must be placed next to the mechanic's
working area, handy for immediate use.
17-12. Pay particular attention that all generator output
phase leads are properly insulated before starting set.
Neglect to do this may result in extensive damage to
equipment and personnel injury. This condition is most
prevalent
when
set
is
started
before
electrical
installation is completed.
CAUTION
For proper unit operation, battery
minus
(-)
terminal
must
be
connected to ground.
