Functional Tests And Adjustments - Generac Power Systems Air-cooled Generators Installation Manual

It will be necessary to determine the order of "shedding" the
connected loads and connect the loads to the LSM in that order.
One is the highest priority and four is the lowest priority.
Perform functional tests in the exact order

presented in this manual, or damage to the
switch could be done.
IMPORTANT: Before proceeding with functional tests, read and
make sure you understand all instructions and information in this
section. Also read the information and instructions of labels and
decals affixed to the switch. Note any options or accessories that
might be installed and review their operation.
This test can be performed with the utility or generator con-
nected to the loads. However if the generator is supplying the
loads and is overloaded the controller may have already turned
off certain loads.
Depress the " TEST " button on the load controller. This function
will disconnect all loads controlled by the controller. The load
controller will then reconnect each load in a timed and staggered
manner as described in the Transfer Switch Owner's Manual.

FUNCTIONAL TESTS AND ADJUSTMENTS

Following transfer switch installation and interconnection,
inspect the entire installation carefully. A competent, qualified
electrician should inspect it. The installation should comply
strictly with all applicable codes, standards, and regulations.
When absolutely certain the installation is proper and correct,
complete a functional test of the system.
