Handling
The crate the switch is packed in is designed to be moved
and lifted using a lift truck. Raised slots in the bottom of
the crate are provided for a lift truck’s forks.
NOTICE
To minimize time-consuming final adjustments
after installation, make sure the switch poles are in
their fully
Closed position during installation of the
interphase and vertical operating pipe sections . S&C
recommends tying the switch blades to their jaw
contacts with wire or a cable tie .
WARNING
DO NOT lift the switch by rigging on the “live parts” or
subject these parts to undue stress from slings or fall
lines .
Lifting the switch by the live parts will damage the
switch . Rough handling may cause damage to the
blades and contacts .
Failure to lift the switch properly can result in
switch damage, causing improper operation,
arcing or electrical shock.
