Section 2 Installation
2.1 Introduction
Kohlerr transfer switches are shipped factory-wired,
factory-tested, and ready for installation. Have the
equipment installed only by trained and qualified
personnel, and verify that the installation complies with
applicable codes and standards. Switch installation
includes the following steps:
D Unpacking and inspecting the transfer switch upon
receipt.
D Verifying that the transfer switch voltage and
frequency ratings match the voltages and
frequencies of the sources.
D Mounting the transfer switch.
D Checking the manual operation.
D Wiring the normal power source (utility), emergency
power source (generator set), and load circuits.
D Wiring the generator set engine start connection.
D Connecting accessories, if provided.
D Connecting and initializing the electrical controls, as
required.
D Checking voltages and operation.
Protect the switch against damage before and during
installation.
The functional tests in Section 3.7 are a necessary part
of the installation. Be sure to perform the functional
tests, which include voltage checks and operation tests,
before putting the transfer switch into service.
2.2 Receipt of Unit
2.2.1 Inspection
At the time of delivery, inspect the packaging and the
transfer switch for signs of shipping damage. Unpack
the transfer switch as soon as possible and inspect the
exterior and interior for shipping damage. If damage
and/or rough handling is evident, immediately file a
damage claim with the transportation company.
2.2.2 Lifting
Unbalanced weight.
Improper lifting can cause severe
injury or death and equipment
damage.
Use adequate lifting capacity.
Never leave the transfer switch
standing upright unless it is securely
bolted in place or stabilized.
WARNING
See Figure 2-1 through Figure 2-4 or the dimensional
drawing for the weight of the transfer switch. Use a
spreader bar to lift the transfer switch. Attach the bar
only to the enclosure’s mounting holes or lifting
brackets; do not lift the unit any other way. Close and
latch the enclosure door before moving the unit.
