Doc. no.IZ*-OMR0035-A 3. Installation and Wiring Do not install the Ionizer in a place where static electricity or noise is generated. The effect of the static neutralization varies depending on the surrounding installation and operating conditions. Confirm the effect of the static neutralization after installation. 3-1 Installation 3-1-1.
Doc. no.IZ*-OMR0035-A 3-1-2. Installation of Ionizer 1) Installation with bracket When installing the Ionizer with a bracket, secure it with M5 screws using the mounting holes on the bottom of the bracket (The screws need to be prepared by the user). Refer to "6.
Doc. no.IZ*-OMR0035-A 3-2. Wiring 3-2-1. Connection Circuit Wire cables according to the connection circuit and wiring chart. Make sure to ground the ground terminal (F.G.) with a ground resistance of 100Ω or less. The ground terminal (F.G.) is used as a reference electric potential for static neutralization. If the ground terminal is not grounded, the Ionizer will not be able to achieve the optimal offset voltage (ion balance).

Doc. no.IZ*-OMR0035-A 4-4. Emitter Dirt Detection and Cleaning If the ionizer is used for an extended period of time, contamination such as dust will stick to the emitters, reducing the static neutralization performance. This product has a function which monitors the emitter contamination all the time. When the emitter contamination is detected, it is indicated by the maintenance signal and LED.
Doc. no.IZ*-OMR0035-A Felt 2 replacement felt pads included Rubber grindstone Cleaning kit (IZS30-M2) The cleaning kit has a felt pad and a rubber grindstone. Choose the felt or rubber grindstone depending on the level of contamination to effectively clean the emitters. Felt: Use for normal cleaning.
Doc. no.IZ*-OMR0035-A 4-4-3. Automatic Cleaning Unit Assembly The assembly procedure of the automatic cleaning unit is as follows: 1) Remove the emitter cartridge from the body referring to "4-5. Replacement of Emitter Cartridge". 2) Insert the parts B of the automatic cleaning unit into the parts A of the body. 3) Slide the automatic cleaning unit in direction C.
Doc. no.IZ*-OMR0035-A 4-4-4. Replacement of Cleaning Arm The replacement procedure of the cleaning arm mounted on the automatic cleaning unit is as follows: 1) Refer to "4-4-3. Automatic Cleaning Unit Assembly", remove the automatic cleaning unit by following the reverse procedure. 2) Hold the motor shaft mounting part of the cleaning arm with a tool such as pliers, and pull it out in A direction while the part B is being held.
Doc. no.IZ*-OMR0035-A 4-5. Replacement of Emitter Cartridge If the emitters are worn out or damaged, replace the emitter cartridge. Before replacing the emitters, make sure that the power supply is OFF and confirm that the fan motor stops. Fan motor rotates due to inertial force even when supplying power is stopped. Confirm that the fan stops before performing repair work.

Doc. no.IZ*-OMR0035-A 2) Incorrect high voltage When incorrect electric discharge is generated during the ionizer operation, the abnormal signal will be turned OFF (ON when it is normal), and the ION/HV LED (red) will light up to indicate the error. When the failure occurs, the fan motor rotation and ion generation are stopped.
Doc. no.IZ*-OMR0035-A 4-7. Offset Voltage Performance Maintaining Function This product uses corona discharge for ion generation, and DC method for voltage application. Although the ion generation efficiency of the DC method is high, the contamination and/or wear level are different between the plus emitters and minus emitters when the product is used for a long period of time. Therefore, the offset voltage (ion balance) performance will be deteriorated quickly.
Doc. no.IZ*-OMR0035-A 4-8. Louver (Option) By mounting a louver onto this product, the generated ions can be diffused or sent with focusing. When diffusing the generated ions, the static neutralization area can be wider in one direction by extending the area to an oval area compared to a circular area. When the louver is mounted so that its adjuster moves horizontally, the ionized air spreads out as shown in the figure.
Doc. no.IZ*-OMR0035-A The angle of the louver can Indicator be adjusted by sliding the adjuster of the louver. Right and left sides can be adjusted individually depending on the static neutralization area and/or direction. The indicator shows the adjustment position. Louver Louver adjustment adjustment...
Doc. no.IZ*-OMR0035-A 5. Performance Performance data shown in this chapter is based on an electrified plate (dimensions: 150 x 150 mm, electrostatic capacity: 20pF) defined by ANSI standard (ANSI/ESD STM3.1-2006). Use this data as a guideline for selection, as the performance data may vary depending on the material and size of the work piece. 5 -1.
