TP-6322 9/04 9Section 3 Scheduled Maintenance
Section 3 Scheduled Maintenance
Scheduled preventive maintenance ensures safe and
reliable operation and extends the life of the transfer
switch. Preventive maintenance includes periodic
testing, cleaning, inspecting, and replacing of worn or
missing components.
A local authorized distributor/dealer can provide
complete preventive maintenance and services to keep
the transfer switch in top condition. Contact a local
distributor/dealer for additional information. See the
Service Assistance section in the Introduction for how to
locate a local distributor/dealer.
Read this entire section carefully before attempting any
maintenance or service. Unless otherwise specified,
have maintenance or service performed by an
authorized distributor/dealer that has trained and
qualified personnel who follow all applicable codes and
standards.
Keep records of all maintenance or service.
Replace all barriers and close and lock the enclosure
door after maintenance or service and before reapplying
power.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or connected equipment, disable the generator
set as follows: (1) Move the generator set master switch to the
OFF position. (2) Disconnect the power to the battery charger.
(3) Remove the battery cables, negative (--) lead first.
Reconnect the negative ( --) lead last when reconnecting the
battery. Follow these precautions to prevent starting of the
generator set by an automatic transfer switch, remote
start/stop switch, or engine start command from a remote
computer.
Hazardous voltage.
Will cause severe injury or death.
Only authorized personnel should
open the enclosure.
DANGER
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
areinplace.
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.
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.
Testing live electrical circuits. Hazardous voltage or
current can cause severe injury or death. Have trained and
qualified personnel take diagnostic m easurements 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.
