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. Verify that the installation complies with
applicable codes and standards. 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 Wire 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 Connect and initialize the electrical controls, as
required.
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 use as a disconnect device.
The functional tests in Section 3 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 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 2-1 for acceptable storage temperatures.
