6.Be sure to ground the DC1 (-) lead wire [blue] of the power supply cable (Resistance between the lead wire and the earth ground should be 100Ω or less.)

If the lead wire is not grounded, the ion balance will be unstable, and an electric shock may occur. At the same time, the ionizer and power supply might be damaged.

Keep the detecting hole of the sensor head towards the charged object to precisely detect the target’s static charge. Keep the distance between the detecting hole and surface of the charged object within 10 to 50mm to prevent the sensor from coming in contact with the charged object. The detecting range and sensor output will be changed depending on the installation distance.

Mount the sensor head with two pieces of M3 screws (sold separately).

As the sensor head case is connected to the GND, pay great attention to the installation or power supply to prevent

short-circuit between the GND and 24V power supply.Detecting hole The detecting hole is open to detect static electricity. When

foreign substances are intruded into the hole or tools come in contact with the inside of the detecting hole, it leads to a malfunction or damage of the sensor, resulting in an improper detection of the static electricity. Therefore, do not put any foreign substances in the detecting hole or touch it with a tool.

Do not pull a cable out of the sensor head. If the cable is pulled with a strong force, the sensor head might be damaged or its wires might be broken.
