About the 620L 0075 400 0010 UK ENW 0000 000 B0 000 000
The Eurotherm 620L 0075 400 0010 UK ENW 0000 000 B0 000 000 enables speed control of induction motors with an encoder. It also provides for a co-processor and ports for a fibre optic communications network.
To ensure the reliability, safety, and performance of the Eurotherm 620L 0075 400 0010 UK ENW 0000 000 B0 000 000, you must reduce or eliminate any interference with the control cables, on any other signal cables.
So, when you plan the installation follow the recommendations for electromagnetic interference (EMC) and cable routing. It is best to only have one ground cable attached to each ground terminal.
When you install the motor cables only use the shortest cable lengths. The motorcables will cause interference and shortest cable will reduce the opportunity for interference.
If you need to power several motors, use a star connection at a junction box instead of individual motor cables. Motor cables and other cables cause interference. Keep sensitive signal cables away from the noisy cables as far as possible.
If you must run sensitive and noisy cables in parallel, keeps the parallel runs to a minimum. If you can’t avoid parallel runs, separate the cables farther apart for the longer runs.
It is best practice to only cross sensitive signal cables and noisy cables at 90 degree angles. Finally, keep sensitive cables away from the motor or other noisy circuits.
