Turn off the main circuit breakers of all
transfer switch power sources and
disable all generator sets as follows:
(1) Move all generator set master
controller switches to the OFF
position. (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
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,

NOTICE
Hardware damage. The transfer
switch may use both
Standard and metric hardware. Use
the correct size tools to prevent
rounding of the bolt heads and nuts.
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
completed.
NOTICE
Electrostatic discharge damage.
Electrostatic discharge
damages electronic circuit boards.
Prevent electrostatic
damage by wearing an approved
grounding wrist strap when handling
electronic circuit boards or integrated
circuits. An approved grounding wrist
strap provides a high resistance (about
1 megohm), not a direct short, to
ground.
