When you install the Eurotherm 620L 0022 400 0010 UK ENW 0000 000 B0 000 000 you have to wire the power cables and control cables. When you plan and install the power cables, you have to follow all local and national standards and codes. In fact, it is best practice to exceed all standards and codes. In addition to the standards and codes, consider the following guidelines.
The power cables must be rated as exceeding the expected supply current by 110 percent.
Route the power cables away from all signal cables. This applies to setpoint or feedback cables, motor feedback cables, and cables from other equipment in the plant.
Use shielded cable to avoid causing interference to other equipment. The main power supply must be 3-phase power and must meet the specifications listed for the device.
The control wiring carries the signals used to control the motor and all other equipment. Use 18 gauge wire for the control cables. The control cables for speed demand are connected to the speed inputs. You can use the control panel to set the motor speed.
If an error is detected concerning the motor speed, an error or alarm is displayed on the control panel and an LED provides more information.
