ratings match the voltages and frequencies of the
sources.
D Install the transfer switch.
D Check the manual operation.
D Connect the controller harness and ground lead.
D Connect the generator set engine start leads.
D Connect the normal power source (utility),
emergency power source (generator set), and load
circuits.
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 5 a re a necessary part of
the installation. Be sure to perform the functional tests,
which include voltage checks and operation tests,
