Tips

For optimal performance, ensure the switch is installed in a clean, dry environment and that all terminal screws are tightened to the specified torque. Use appropriate cable glands to maintain the IP65 rating at the front. When switching motors, verify that the rated power matches the AC-3 or AC-23A utilization category to avoid contact wear.
