Product Description
The Eurotherm 620L00224000010 enables speed control of induction motors with an encoder. It also provides for a co-processor and ports for a fibre optic communications network. You must plan ahead before you install the Eurotherm 620L00224000010. The installation of the Eurotherm 620L00224000010 is designed to be simple and straightforward, but it is important to consider certification, cable routing, power supply requirements, and other factors.
Most local building, electrical, and building codes require that the installation be certified by a national certification organization. Make sure you understand the requirements of the certification organization. For example, for certification in the US, by the Underwriters Laboratories, several requirements must be met. The installer has to provide external motor overload protection. This is a thermal device on the motor. The installer or the local inspector has to determine if the external motor overload protection meets all national and local requirements.
Another requirement for UL certification is that the fuses used for branch circuits meet all national and local requirements. The fuse requirements are given for the motor horsepower at a given DC voltage. Another requirement for UL certification in the US concerns cabling requirements. The cables must meet a specific temperature rating and the cables must be copper. For example, one requirement is that the cables are rated for 75 degree Celsius only. Another requirement is for the torque tightening requirements. This requirement prevents damage to the terminals through over tightening and ensures the terminal are tight enough to clamp the cables securely.
