Standard- Transition Switches
Hazardous voltage.
Will cause severe injury or death.
Disconnect all power sources before
opening the enclosure.
DANGER
Servicing the transfer switch. Hazardous voltage can
cause severe injury or death.
Deenergize all power sources
before servicing. Turn off the main circuit breakers of all
transfer switch power sources and disable all generator sets
as follows: (1) Press the generator set off/reset button to shut
down the generator set. (2) Disconnect power to all battery
chargers. (3) Disconnect all battery cables, negative (--) leads
first. Reconnect negative (--) leads last when reconnecting the
battery cables after servicing. Follow these precautions to
prevent the starting of generator sets by an automatic transfer
switch, remote start/stop switch, or engine start command
from a remote computer. Before servicing any components
inside the enclosure: (1) Remove all jewelry. (2) Stand on a
dry, approved electrically insulated mat. (3) Test circuits with a
voltmeter to verify that they are deenergized.
Note:
A manual operation handle is provided on the
transfer switch
for maintenance purposes only
. Do
not use the manual operation handle to transfer
the load with the power connected.
Use the manual operation handle to check the manual
operation before energizing the transfer switch. Use the
following manual operation procedures to verify that the
contactor operates smoothly without binding.
Note:
A contactor in normal and serviceable condition
operates smoothly without binding. Do not place
the transfer switch into service if the contactor
does not operate smoothly; contact an
authorized distributor/dealer to service the
contactor.
