ATS Catalog Numbering System1.4 Environmental and Operational ConditionsNormally, an ATS is applied indoors in an electrical equipmentroom. It can also be used for normal outdoor applications (withstandard NEMA 3R enclosure) where the equipment is subject tofalling rain, freezing temperatures, and 95% humidity (non-con-densing). The ambient temperature range for operation isbetween -20 and 70°C (-4 and 158°F).1.5 GlossaryWith respect to their use within this document and as they relateto transfer switch and controller operation, the following terminol-ogy is defined.AvailableA source is defined as “available” when it is within its undervolt-age setpoint ranges for the nominal voltage setting.ConnectedConnected is defined as when the input is shorted by an externalcontact or connection.Failed or FailsA source is defined as “failed” when it is outside of the applicablevoltage setpoint ranges for the nominal voltage and for a timeexceeding 0.5 seconds after the time delay emergency fail (TDEF)time delays expires.FailsafeFailsafe is a feature that prevents disconnection from the onlyavailable power source and also forces a transfer or re-transferoperation to the only available power source.Re-TransferRe-transfer is defined as a change of the load connection from theGenerator to the Utility.UtilityUtility is the primary source (normal source, normal power source,or normal).GeneratorGenerator is the secondary source (generator emergency source,emergency power source, emergency, standby, or backupsource).Utility: Failed or FailsUtility is defined as “failed” when it is outside of its undervoltagesetpoint ranges for the nominal voltage and frequency setting.Generator: Failed or FailsGenerator is defined as “failed” when it is outside of its undervolt-age/underfrequency/overfrequency (if applicable) setpoint rangesfor the nominal voltage and frequency setting for a time exceeding0.5 seconds after the Time Delay Emergency Fail (TDEF) timedelay expires.TransferTransfer is defined as a change of the load connection from theUtility to the Generator power source.UnconnectedUnconnected is defined as when the input is not shorted by anexternal contact or connection.100100 = 100 ALoadcenterL24 - 24 CircuitL 24 REnclosure TypeR = Type 3REaton GeneratorSwitch
