Attach the Eurotherm 620L 0450 400 0010 US ENW 0000 000 B0 000 000 to a wall using four screws or bolts. The wall has to be cool to assist with the buildup of heat and the wall has to be solid to support the weight of the device. If attached to a wall, the Eurotherm 620L 0450 400 0010 US ENW 0000 000 B0 000 000 is to designed to allow for the free flow of air from the bottom of the device through the top.
Make sure the wall is cool and no devices are behind the wall that will heat the wall. Also make sure no other devices are close to the device that will generate heat or block the flow of air.
The power cables should be at a minimum 110% over the requirement for the voltage. Also, keep the 3-phase power cables well clear of the control cables that carry feedback or setpoint signals. This is to protect against interference. The motor power supply cables should always be shielded to protect other devices in the surrounding area from interference. The main power supply must be 3-phase power and within the tolerances specified for the device.
