opening the enclosure.
DANGER
Servicing the transfer switch. Hazardous voltage will
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.
NOTICE
Improper operator handle usage.
Use the manual operator
handle on the transfer switch for maintenance purposes only.
Return the transfer switch to the normal position. Remove the
manual operator handle, if used, and store it in the place
provided on the transfer switch when service is completed.
Disable the generator set to prevent it from starting and
disconnect both power sources before manually
operating the switch.
Do not place the transfer switch into service if the
contactor does not operate smoothly; contact an
authorized distributor/dealer to service the contactor.
Remove any shipping angles, which are identified by a
yellow sticker, before attempting to operate the transfer
switch.
Note: Bypass and isolate the transfer switch before
using the maintenance handle.
See Section 7
for bypass and isolation procedures.
A detachable manual operator handle is provided on the
transfer switch for maintenance purposes only. Use the
following manual operation procedures to verify that the
contactor operates smoothly without binding.
On
programmed-transition and closed-transition models,
check the operation of both the Normal and Emergency
operators.
Note:
A contactor in normal and serviceable condition
operates smoothly without binding.
If the
contactor does not operate smoothly, contact an
authorized distributor/dealer to service the
contactor.
