This function-ality requires that Load monitoring CT’s are installed (sold separately)1.3 Transfer Switch Catalogue Number IdentificationATS equipment catalogue numbers provide a significant amountof relevant information pertaining to a specific piece of equipment.The Catalogue Number Identification Table (see Table 1) provides therequired interpretation information.Table 1. ATS Catalogue Numbering System.1.4 Environmental and Operational ConditionsNormally, an ATS is applied indoors in an electrical equipment room.It can also be used for normal outdoor applications (with standardtype 3R enclosure) where the equipment is subject to falling rain,freezing temperatures, and 95% humidity (non-condensing). Theambient temperature range for operation is between -20 and 70°C(-4 and 158°F)..E GS CA 200A SEampererating100 or200TransferControlC = RelayCA=RTC100TypeGeneratorSwitchManufacturerEatonServiceEntranceCanadianService EntranceApproved
