SECTION 2: RECEIVING, HANDLING, AND
STORAGE
2.1 Receiving
Every effort is made to ensure that the ATS equipment arrives at
its destination undamaged and ready for installation. The packing
is designed to protect the internal components as well as the
enclosure. Care should be exercised, however, to protect the
equipment from impact at all times. Do not remove the protective
packaging until the equipment is at the installation site and ready
to be installed.
When the ATS equipment reaches its destination, the customer
should inspect the shipping container for any obvious signs of
rough handling and/or external damage that occurred during trans-
portation. Record any external and internal damage for reporting
to the transportation carrier and to the Eaton sales representative,
once a thorough inspection is complete. All claims should be as
specific as possible and include the Shop Order and General Order
numbers.
A shipping label affixed to the shipping container includes a vari-
ety of equipment and customer information, such as General
Order and catalog numbers. Make certain that this information
matches the other shipping paper information.
Each ATS enclosure is packaged in its own box. Do not discard
the packing material until the equipment is ready for installation.
Once the packaging is removed from the shipment, the enclosure
door can be opened. A plastic bag of documents will be found in
the enclosure. Important documents, such as wiring diagrams and
appropriate instruction leaflets are enclosed within the bag and
should be filed in a safe place.
2.2 Handling
As previously mentioned, ATS equipment is packaged in its own
box. Protect the equipment from impact at all times and do not
double stack. Once the equipment is at the installation site and
ready to be installed, the packaging material can be removed.
Refer to Section 4 of this manual for specific installation instruc-
tions.
2.3 Storage
Although well packaged, this equipment is not suitable for outdoor
storage. The equipment warranty will not be applicable if there is
evidence of outdoor storage. If the equipment is to be stored
indoors for any period of time, it should be stored with its protec-
tive packaging material in place. Protect the equipment at all
times from excessive moisture, construction dirt, corrosive condi-
tions, and other contaminants. It is strongly suggested that the
package-protected equipment be stored in a climate-controlled
environment of -20 to 65°C (-4 to 149°F), with a relative humid-
ity of 80% or less. Do not, under any circumstance, stack other
equipment on top of an ATS equipment enclosure, whether pack-
aged or not.
SECTION 3: EQUIPMENT DESCRIPTION
3.1 Introduction
The Eaton Residential ATS is assembled and tested at the factory.
It is designed to be used in conjunction with standby power distri-
bution equipment to provide an alternate source of power to criti-
cal circuits in the event that the primary power source is
interrupted.
This ATS monitors both utility and generator power sources and
automatically transfers critical load circuits between the two
sources, depending on which source is available. The utility
power source is preferred and will remain connected to the switch
if it is available.
3.2 Power Panel
The power panel is used for making load, power, and neutral con-
nections. The power contactor is mounted on a steel baseplate
(Figure 6).
3.2.1 Main Contacts
This ATS incorporates a power contactor. The main contacts con-
nect and disconnect the load to and from the different power
sources. The power contactor is mechanically and electrically
interlocked to prevent the two sets of main contacts from being
closed simultaneously.
