Safety

Turn OFF all power before installation, adjustment, or removal of transfer switch or any of its components.
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.
CAUTION
Due to hazardous voltage and current,
recommends that an ABB
or a qualified electrician must perform the
installation and maintenance 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.
WARNING
Do not use a blower since debris may
become lodged in the electrical and
mechanical components and cause damage.

Mounting

Adequate lifting means must be used to mount the transfer
switch into place. The recommended method for moving
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.
CAUTION
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.
