O & M Manual for the CHGENLC Automatic 

Transfer Switch with ATC-100 Control

Re-Transfer

Re-transfer is defined as a change of the load connection from the 

Generator to the Utility.

Utility

Utility is the primary source (normal source, normal power source, 

or normal).

Generator

Generator is the secondary source (generator emergency source, 

emergency power source, emergency, standby, or backup 

source).

Utility: Failed or Fails

Utility is defined as “failed” when it is outside of its undervoltage 

setpoint ranges for the nominal voltage and frequency setting.

Generator: Failed or Fails

Generator is defined as “failed” when it is outside of its undervolt-

age/underfrequency/overfrequency (if applicable) setpoint ranges 

for the nominal voltage and frequency setting for a time exceeding 

0.5 seconds after the Time Delay Emergency Fail (TDEF) time 

delay expires.

Transfer

Transfer is defined as a change of the load connection from the 
Utility to the Generator power source.

Unconnected

Unconnected is defined as when the input is not shorted by an 

external contact or connection.

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.
