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.
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 the
required clearance for transfer switch drawout. Provide
cable bending space and clearance to live metal parts.
Outdoor installations.
Transfer switches with
NEMA 3R, 4, or 4X enclosures can be installed
outdoors.
In locations with very high ambient
temperatures, installation in a shaded area or a location
with the enclosure door facing away from direct sunlight
is recommended.
Prepare the foundation.
Ensure that the supporting
foundation for the enclosure is level and straight. The
floor must be flat and level. Refer to the dimension
drawing provided with the switch for required clearance.
For 1600--4000 amp models, allow at least 0.9 meters
(35 inches) to roll out the transfer switch.
For bottom cable entry, if used, install conduit stubs in
the foundation. Refer to the enclosure dimension
drawing for the conduit stub locations. Provide cable
bending space and clearance to live metal parts. When
pouring a concrete floor, use interlocking conduit spacer
caps or a wood or metal template to maintain proper
conduit alignment.
Installation of IBC seismically certified or California
OSHPD approved transfer switches.
IBC Seismic
certification or California OSHPD approval must be
requested when the transfer switch is ordered. See
Section 2.4 and the ADV drawings for additional
installation requirements for transfer switches with IBC
seismic certification or California OSHPD approval.
Correctly installed transfer switches with California
OSHPD approval also have IBC seismic certification.
Install the transfer switch.
Refer to the dimension
drawing supplied with the switch and mount the transfer
switch according to the details and instructions on the
drawing.
When drilling entry holes for any conductors, cover the
transfer switch components for protection from metal
chips and construction grit.
Note:
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.
