7.1.1 Mounting / Lifting
Proper lifting equipment must be used to
mount the Bypass-isolation transfer
switch cabinet into place (Note: The
weight of 4-pole Standard ABB Zenith By-
pass-Isolation automatic transfer switch
is 775kg/1709 lb, see the weight informa-
tion in Dimension Drawings ). The recom-
mended method for moving the cabinet is
ZBTS using the lifting eyes. Enough room
should be allowed to open the cabinet
doors fully for inspection and servicing of
the switches per NEC and local codes.

Warning
Before drilling conduit entry holes or any ac-
cessory mounting holes, cover and protect
the switch and control panel to prevent dirt
and metal fragments from entering the me-
chanical and electrical components.
Failure to do so may result in damage and
malfunction of the switch.
Danger
Hazardous voltage may be present. Only an au-
thorised electrician may perform the electri-
cal installation and maintenance of OX_ auto-
matic transfer switches. Do not attempt any
installation or maintenance actions when By-
pass-Isolation automatic transfer switch is
connected to the electrical mains. Before
starting work, make sure that the switch is
de-energised.
Warning
Not following ABB lifting guidelines may re-
sult in severe injury or death.
