Section 2 Installation
2.1 Introduction
Kohlerr transfer switches are shipped factory-wired,
factory-tested, and ready for installation.
Have the equipment installed only be trained and
qualified personnel. The installation must comply with
applicable codes and standards.
Switch installation includes the following steps:
D Unpack and inspect the transfer switch upon receipt.
D Verify that the transfer switch voltage and frequency
ratings match the voltages and frequencies of the
sources.
D Mount the transfer switch.
D Check the manual operation.
D Connect the controller harness and ground lead.
D Connect the normal power source (utility),
emergency power source (generator set), and load
circuits.
D Connect the generator set engine start leads.
D Connect accessories, if provided.
D Check voltages and operation.
Protect the switch against damage before and during
installation.
Note: A protective device such as a molded-case circuit
breaker or fused disconnect switch MUST be
installed on both sources of incoming power for
circuit protection and used as a disconnect
device.
The functional tests in Section 6 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.
