Installation
We sincerely appreciate your patronage and have made
significant effort to provide for a safe, streamlined and cost-
effective installation. Because each installation is unique, it is
impossible to know of and advise the trade of all conceivable
procedures and methods by which installation might be
achieved. Neither could we know of possible hazards and/or
the results of each method
or procedure.
For these reasons, only current licensed electrical
professionals should attempt system installations.
Installations must strictly comply with all applicable
codes, industry standards and regulations.
Your equipment is supplied with this Installation Manual
and a separate Operator’s Manual. These are important
documents and should be retained by the owner after the
installation has
been completed.
Every effort has been made to make sure that the information
in this manual is both accurate and current. However, the
manufacturer reserves the right to change, alter or otherwise
improve the system at any time without prior notice.
Owner Responsibilities
To help you make informed choices and communicate
effectively with your installation contractor(s), read and
understand Owner Orientation before contracting or
starting your
equipment installation.
To arrange for proper installation, contact the store at which
you purchased your equipment, your dealer, or your utility
power provider.
The equipment warranty is VOID unless the system is
installed by licensed electrical professionals.
Owner Orientation
The illustrations provided are for typical circumstances and
are meant to familiarize you with the installation options
available with your system.
Local codes, appearance, and distances are the factors
that must be considered when planning an installation. As
the distance from the existing electrical service increases,
compensation in wiring materials must be allowed for. This
is necessary to comply with local codes and overcome
electrical voltage drops.
These factors will have a direct effect on the overall
price of your equipment installation.
Your installer must check local codes AND obtain permits
before installing the system.
• Read and follow the instructions given in this manual.
• Follow a regular schedule in caring for and using your
equipment, as specified in this manual.
Installing Dealer/Contractor Responsibilities
• Read and observe the Important Safety Instructions.
• Read and follow the instructions given in this manual.
• The installer may need to provide appropriate rated
contactors based on loads to be controlled.
• Check federal and local codes and authority having
jurisdiction, for questions on installation.
• Ensure generator is not overloaded with selected loads.

Equipment Description
The transfer switch is designed to transfer selected loads
found in normal residential installations to standby power in
the event of a primary power outage. The load is connected
either to utility power (normal) or standby power (generator).
The transfer switch monitors utility and generator voltages
and will automatically connect loads to the appropriate
source of power.
Only a licensed electrician should complete a standby
installation. Service conduit and conductors can be wired
directly from the watt-hour meter to the transfer switch. A
separate service entrance disconnect and associated wiring
is not required when installed per applicable federal, state
and local codes, standards and regulations.
Major components of the transfer switch are a 2 pole double
throw transfer switch, control circuit board, fused utility
terminals and interconnecting wiring. The control board also
has two inputs for current transformers that sense generator
current.
The transfer switch is solenoid-operated from utility or
generator inputs and contain suitable mechanical and
electrical interlock switches to eliminate the possibility of
connecting the utility service to the generator output. It
has ratings capable of switching full utility power into the
residence. In addition, a manual override lever is provided for
the transfer function.
The control board has active circuits sensing utility and
generator voltages. It creates a signal for generator start-up,
switch transfer and retransfer when utility is restored. The
control board also contains red and green LEDs indicating
the power source available and two relay operated contacts
that provide supervisory control of external loads.
