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 enclo-
sure. Care should be exercised, however, to protect the equipment
from impact at all times. Do not remove the protective packag-
ing 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 transporta-
tion. 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 variety
of equipment and customer information, such as General Order and
catalogue 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 instructions.
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 conditions,
and other contaminants. It is strongly suggested that the package-
protected equipment be stored in a climate-controlled environment
of -20 to 70°C (-4 to 158°F), with a relative humidity of 80% or less.
Do not, under any circumstance, stack other equipment on top of an
ATS equipment enclosure, whether packaged or not.
Section 3: Equipment Description
3.1 Introduction
The Eaton metered, service entrance rated ATS is assembled and
tested at the factory. It is designed to be used in conjunction with
standby power distribution equipment to provide an alternate source
of power to critical 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 sourc-
es, 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 Meter Socket and Service Disconnect
The meter socket section of the ATS is used for making the primary
utility power, and neutral connections. Factory cabling from the load
side of the meter jaws carrys utility power to the circuit breaker
service disconnect and on to the utility lugs of the power contactor
assembly.
(Figure 6).
3.2.1 Main Contacts
This ATS incorporates a power contactor. The main contacts connect
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 simultane-
ously.
