Storage
Store the transfer switch in its protective packing until
final installation. Protect the transfer switch at all times
from moisture, construction grit, and metal chips. Avoid
storage in low-temperature and high-humidity areas
where moisture could condense on the unit.
See
Figure 2-5 for acceptable storage temperatures.

Unpacking
Allow the equipment to warm to room temperature for at
least
24 hours
before
unpacking
to
prevent
condensation on the electrical apparatus. Use care
when unpacking to avoid damaging transfer switch
components. Remove dirt and packing material that
may have accumulated in the transfer switch or any of its
components. Do not use compressed air to clean the
switch. Cleaning with compressed air can cause debris
to lodge in the components and damage the switch.
For 600--800 amp transfer switches, remove the lag
screws that secure the transfer switch to the shipping
skid. For 1000--4000 amp transfer switches, open the
enclosure door to remove the lag screws that secure the
transfer switch to the skid.
2.3 Mechanical Installation
NOTICE
Foreign material contamination.
Cover the transfer switch
during installation to keep dirt, grit, metal drill chips, and other
debris out of the components. Cover the solenoid mechanism
during installation. After installation, use the manual operating
handle to cycle the contactor to verify that it operates freely.
Do not use a screwdriver to force the contactor mechanism.
NOTICE
Hardware damage.
The transfer switch may use both
American Standard and metric hardware. Use the correct size
tools to prevent rounding of the bolt heads and nuts.
Check the system voltage and frequency
. Compare
the voltage and frequency shown on the transfer switch
nameplate to the source voltage and frequency. Do not
install the transfer switch if the system voltage and
frequency are different from the nominal normal (utility)
source
voltage
and
frequency
or
the
nominal
emergency source voltage and frequency shown on the
generator set nameplate.
Plan the installation
. Use the dimensions given on the
enclosure dimension (ADV) drawings.
Select a
mounting site that complies with local electrical code
restrictions for the enclosure type. Mount the transfer
switch as close to the load and power sources as
possible.
Allow adequate space to fully open the
enclosure and to service the switch.
Provide cable
bending space and clearance to live metal parts.
Prepare the foundation.
Ensure that the supporting
foundation for the enclosure is level and straight. For
bottom cable entry, if used, install conduit stubs in the
foundation. Refer to the enclosure dimension drawing
for the conduit stub locations. When pouring a concrete
floor, use interlocking conduit spacer caps or a wood or
metal template to maintain proper conduit alignment.
Install the ATS.
For easy access during installation and
wiring, remove the front door of the enclosure. For
30--200 amp switches, support the door and remove the
two screws at the bottom. Slide the door down until the
top clears the enclosure. Open the door wide enough to
reach the controller wiring on the inside of the door.
Disconnect the cable plug that connects the front door
components to the internal components and disconnect
the grounding wire between the door and the enclosure.
Set the door out of the way to protect the controls.
