Installation of the Eurotherm 620L-0015-400-0010-US-ENW-0000-000-B0-000-000 in the United States requires that the device meet local and national codes and requirements. Many local building, manufacturing, and electrical codes require that the device meet a national certification.
To meet the UL certification you must install an overload protection device. This is a thermal device on the motor winding and it is the responsibility of the installer or the local inspector to ensure the overload protection meets the UL requirement. If the motor overheats due to overload the motor will stop.
Another requirement for UL listing is the fuses used on the branch circuits. The fuses are rated for horsepower and amps. The installer and inspector must ensure that the fuses in the device meet all requirements.
The installer must consider the rating of the cables used for the 3-phase power connections. The cables must be copper cables and be rated for 75 centigrade temperature. Also a requirement exists for the operating temperature. The technical specification lists the operating temperature for your model. Be sure to provide proper air flow. If the device is in an enclosed area, you might need to have a ventilation system with forced air circulation.
Another requirement for UL certification is to follow all terminal markings. That is, you must adhere to the electrical drawings provided in the wire diagrams to ensure proper connections.
