Mounting
Adequate lifting means must be used to mount the transfer

the transfer switch using the lifting eyes, where supplied,
and a spreader bar is illustrated in
Figure 1
. Enough room
should be allowed to open the cabinet doors fully for
inspection and servicing of the switch per NEC and
local codes.
The safe operation of your switch is
ABB
Zenith’s focus.
The proper storage, installation, operation and maintenance
will help increase the life of the switch.
Equipment Inspection
and Storage
Once you have received the transfer switch, inspect it for
any damage. This includes damage to the enclosure, power
panel, control panel and wiring harness. If any damage
is found or suspected, file a claim as soon as possible with
the carrier and notify the nearest
ABB
Zenith representative.
Before installation, if it is necessary, store the transfer
switch in a clean dry place, protected from dirt and water.
Provide ample air circulation and heat, if necessary, to
prevent condensation.

Final Equipment Inspection
Prior to energizing the transfer switch:
1.
Remove any debris incurred, with a vacuum,
due to shipment or installation.
2.
Verify that all cabled connections are correct
and that phase rotation of both sources match.
3.
Check engine start connections.
4.
Verify the correct connection of all control wires.
5.
Check settings of all timers and adjust as necessary.
6.
Adjust any optional accessories as required.
7.
Check the lug torque values of the power
connections.
NOTE
:
Lug torque values are specified
in table 2 on pg.2.
8.
Make sure that all covers and barriers are
installed and properly fastened.
NOTE
:
Power panels ship from ABB Zenith
in Source 1 Position.
Before drilling conduit entry holes or any
accessory mounting holes, cover and protect
the switch and control panel to prevent dirt
and metal fragments from entering the
mechanical and electrical components.
Failure to do so may result in
damage and malfunction of the switch.
Due to hazardous voltage and current,
ABB
Zenith
recommends that an
ABB
Zenith Certified technician
or a qualified electrician must perform the
installation and maintenance of the switch.
Do not use a blower since debris may
become lodged in the electrical and
mechanical components and cause damage.
HAZARDOUS VOLTAGE
(Can Cause Severe Injury or Death)
Turn OFF all power before installation, adjustment, or removal of transfer switch or any of its components.
