Operation
DANGER
Electrocution. Do not manually transfer under load.
Disconnect transfer switch from all power sources
prior to manual transfer. Failure to do so will result
in death or serious injury, and equipment damage.
Prior to automatic operation, manually exercise the
transfer switch to verify that there is no binding or
interference with proper operation of the mechanism.
Manual operation of the transfer switch is required if
automatic operation fails.
IMPORTANT NOTE: Always use the applicable transfer
switch owner's manual for actual manual transfer switch
operation instructions. The information presented here
describes a typical V-style transfer switch, which is not
used for three phase applications.

Transfer to Generator Power
