Transfer Switch Manual Operation
DANGER
Electrocution. Do not manually transfer under
load. Disconnect transfer switch from all
power sources prior to manual transfer. Fail-
ure to do so will result in death or serious in-
jury, and equipment damage.
Manually exercise the transfer switch prior to automatic
operation to verify there is no binding or interference with
correct operation of the mechanism. Manual operation of
the transfer switch is required if automatic operation fails.

fer switch owner's manual for actual manual transfer
switch operation instructions. The information pre-
