ATC-100 Contactor Based Transfer Switch
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. Packing is
designed to protect 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 ready for installation.
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 Eaton, once a thorough inspection
is complete. All claims should be as specific as possible and
include the catalog 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 Number and catalog numbers. Make certain that this infor-
mation matches other shipping paper information.
Each transfer switch is packed securely with appropriate shipping
materials to prevent damage during shipment. Do not remove or
discard the packing material until the equipment is ready for instal-
lation
Once the top packaging is removed from the shipment, the enclo-
sure door can be opened. A plastic bag of documents will be
found in the enclosure, usually attached to the inside of the enclo-
sure. Important documents, such as test reports, wiring dia-
grams, 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 for forklift
movement. Protect the equipment from impact at all times and
DO NOT double stack.
Once the equipment is at the installation location and ready to be
installed, packaging material can be removed and discarded. Once
the enclosure is unbolted from the wooden pallet, it can be hand
moved to its installation position. Be careful not to damage the
top or bottom enclosure mounting flanges. 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 condi-
tions, and other contaminants.
It is strongly suggested that the package-protected equipment be
stored in a climate-controlled environment with temperatures from
-30 to 85°C (-22 to 185°F) and with a relative humidity of 80%
or less. DO NOT, under any circumstance, stack other equipment
on top of a transfer switch equipment enclosure, whether pack-
aged or not.
Section 3: Equipment Description
3.1 General
The ATS consists of two basic panels:
1. The power panel; and
2. The microprocessor-based logic panel.
These panels are interconnected via connector plugs and mounted
in an enclosure (Figure 4).
Figure 4. Two Basic Panels of the ATS 400 A Model.
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 5).
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.
