1.4 Environmental Conditions
1.4.1 Operational Conditions
Normally, an ATS is applied indoors in an electrical equipment
room. In the appropriate enclosure, it can be used for outdoor
applications where the equipment is subject to falling rain, freez-
ing temperatures, and no greater than 90% humidity (non-con-
densing). The ambient temperature range for operation is
between -20 and 70°C (-4 to 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 termi-
nology is defined.
Available 
A source is defined as “available” when it is within its undervolt-
age/overvoltage/ underfrequency/overfrequency (if applicable)
setpoint ranges for the nominal voltage and frequency 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 applica-
ble voltage and frequency setpoint ranges for the nominal volt-
age and frequency setting 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 Source 2 to the Source 1.
Source 1 
Source 1 is the primary source (normal source, normal power
source, or normal).
Source 2

Source 2 is the secondary source (emergency source, emer-
gency power source, emergency, standby, or backup source).
Source 1: Failed or Fails 
Source 1 is defined as “failed” when it is outside of its under-
voltage/overvoltage/ underfrequency/overfrequency (if applica-
ble) setpoint ranges for the nominal voltage and frequency
setting.
Source 2: Failed or Fails 
Source 2 is defined as “failed” when it is outside of its under-
voltage/overvoltage/ underfrequency/overfrequency (if applica-
ble) 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
Source 1 to the Source 2 power source.
Unconnected 
Unconnected is defined as when the input is not shorted by an
external contact or connection.
