TECHNICAL BULLETIN TB-2095 Chargebuster Jr. H/O with Emitter Cassette Installation, Operation and Maintenance Made in the United States of America that have large capacitance, like people and carts however, ionizers should be considered as a method for charge neutralization in cases where grounding cannot be achieved. Air ionization can neutralize the static charge on insulated and isolated objects by producing separate charges in the molecules of the gases of the surrounding air. When Removable Cassette an electrostatic charge is present on objects in the work environment, it will be neutralized by attracting opposite polarity charges from the ionized air. Note that ionization systems should not be used as a primary means of charge control on conductors or people. (Reference: IEC 61340-5-2:1 paragraph 5.2.9). The Chargebuster Jr. H/O is available in 2 models: Item Voltage Heater NIST Accessory 60500 120 Volt No Yes Ground 60501 120 Volt Yes Yes Jack All models come equipped with a universal IEC cord connector Power and a removable emitter cassette. Models 60500 and 60501 Switch include a standard IEC cord set. All models are calibrated and On/Off traceable to NIST. Heater Switch IONIZER SELECTION On/Off ANSI/ESD S20.20 paragraph 6.1.1.2. ESD Control Program Plan Guidance states: The Plan should include a listing of the specific type of ESD protective materials and equipment used Figure 1. Desco Chargebuster Jr. H/O (High Output) Ionizer in the Program. When selecting an ionizer life cycle costs should be considered including: equipment cost installation Description cost and operation and maintenance cost. The Desco Chargebuster Jr. H/O ionizer is a compact and lightweight auto-balancing bench top ionizer with our The unit is normally placed at one end of a workbench or area patented* emitter cassette that slides out for easy cleaning and to be neutralized. It may also be wall mounted or mounted on a replacement. The Chargebuster Jr.s unique active feedback shelf.

The units compact, efficient design minimizes bench top space requirements and need for TOP VIEW maintenance, while maximizing neutralization efficiency and overall performance. 18 Ionizers are useful in preventing electrostatic charge generation, ElectroStatic Discharge, ElectroStatic Attraction, as well as preventing equipment latch-up and safety related shock. ANSI/ESD S20.20 Paragraph 6.2.3.1 Protected Areas Requirement states: Ionization or other charge mitigating techniques shall be used at the workstation to neutralize SIDE VIEW electrostatic fields on all process essential insulators if the electrostatic field is considered a threat. Ionization is used to neutralize charges on process necessary insulators 1 and isolated semiconductors. Some examples of process necessary insulators are: the PC board itself, plastic test stands, plastic housing where a PCB may be mounted, as well as computer monitor screens and regular cleaning wipes. 6 42 Examples of floating or isolated conductors are: loaded PCB Figure 2.

Installing Stand Assembly To install the stand assembly follow the instructions shown in Figure 3. You can mount the unit on a bench top or remove the rubber feet and bolt the stand to a wall or under a shelf as desired. Be sure to use appropriate fasteners. For best results, mount the unit so that no obstructions exist either on the intake or the outlet side. Figure 5. Installing Chargebuster Jr. to Ionizer Mounting Arm Ionizer Housing The 60460 is sold separately. For detailed information on the Stand installation and operation of the 60460 Ionizer Mounting Arm, Flat Washer ask for Technical Bulletin TB-2056. Knob Operation For item 60500 set the front panel rocker fan switch to either HIGH or LOW fan speed. Higher air flow will result in a faster neutralization rate. Safety interlock switches are provided internally on the emitter cassette. This insures that power is cut off in the event that the cassette is removed or not fully installed. Figure 3. Installing stand assembly Aim the unit so that the maximum airflow is directed at the items or area to be neutralized. Alternative Mounting Use the 60466 Ionizer Mounting Arm as a mounting alternative The bottom rocker switch on the 60501 turns on a heater which for the Chargebuster Jr. Ionizer.

The Ionizer Mounting Arm includes a C-clamp style mounting system for ease of installation. Figure 4 shows proper mounting of the arm on a workbench. The arm also includes an installed three prong power cord with an IEC termination.
