1.4 Environmental and Operational Conditions
Normally, an ATS is applied indoors in an electrical equipment
room. It can also be used for normal outdoor applications (with
standard NEMA 3R enclosure) where the equipment is subject to
falling rain, freezing temperatures, and 95% humidity (non-con-
densing). The ambient temperature range for operation is
between -20 and 70°C (-4 and 158°F).
1.5 Glossary
With respect to their use within this document and as they relate
to transfer switch and controller operation, the following terminol-
ogy is defined.
Available
A source is defined as "available" when it is within its undervolt-
age setpoint ranges for the nominal voltage setting.
Connected
Connected is defined as when the input is shorted by an external
contact or connection.
Failed or Fails
A source is defined as "failed" when it is outside of the applicable
voltage setpoint ranges for the nominal voltage and for a time
exceeding 0.5 seconds after the time delay emergency fail (TDEF)
time delays expires.
Failsafe
Failsafe is a feature that prevents disconnection from the only
available power source and also forces a transfer or re-transfer
operation to the only available power source.

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.
