USER GUIDE TB-9047 Field Service Kits Installation, Operation and Maintenance Description General Guidelines SCS offers a complete line of field service kits for the electronics field service technician as a simple and The discharge of static electricity can damage many effective means of creating an ESD protected area in of the electronic components used in many types of the field. Per ANSI/ESD S20.20, a protected area may equipment. Electrostatic discharge (ESD) has been be a single workstation (fixed or portable), laboratory, a frequent source of field service failures. Many firms room, building, or any other area with pre-designated are aware of the threat of ESD in the manufacturing boundaries that contains materials and equipment environment and have adopted ESD control programs designed to limit electrostatic potentials. to control static electricity. When working in field service environments similar precautions must be taken since Utilizing Equipotential Bonding per ANSI/ESD S20.20 sensitive components can be damaged by ESD at any and a common point ground system for connecting static time - particularly when boards are being handled. control elements including operator, worksurface, and equipment, these field service kits are manufactured from low charging materials that limit charge generation. Specifications When properly connected, the Field Service Kit mat will share the charge from conductive objects when they are placed on the surface. When neither AC equipment Equipment Grounding Conductor or auxiliary grounds are available, an equipotential bonding system may need to be used. In this situation, all of the items in the system are bonded together so that the charge that resides on the elements will be shared equally and therefore there will be no potential difference between the items. Once this step has been completed it is safe to handle ESD sensitive Figure 2. 8501 Field Service Kit. parts without inducing damage. A real life example of this is often observed in office equipment field service 8501 PORTABLE FIELD SERVICE KIT operations. For safety reasons the service technician Designed to quickly and reliably share static charge will often disconnect the AC power cord which detaches on the technician and worksurface upon which to lay the equipment from ground. In order to safely install parts. The kit includes one Adjustable Wristband and a ESD sensitive products into the equipment, it is static-dissipative worksurface. Both connect to ground or necessary to electrically connect or bond together each other by the Ground Cord Assembly. For detailed the service technician, the equipment frame and the specifications ask for Drawing 8501. Made in China. ESD sensitive product. Once bonded together an ESD event will NOT occur when the technician handles the Surface Resistance 6 9 product or installs it in the office equipment.

Paper, tape, styrofoam cups and clothing can tribocharge, creating potentially damaging static electricity. Being insulators, static charges on these items will NOT be drained away even when placed on grounded field service surface. 2. Unfold the field service kit in a convenient location and verify that the ground cord is firmly connected to the worksurface groundable point snap. Figure 3. 8507 Field Service Kit. 3. If using a wrist strap, first attach the wrist strap cord to the groundable point snap on the worksurface. If the worksurface has more than one groundable 8507 PORTABLE FIELD SERVICE KIT point snap be sure to make contact to the same The 8507 Portable Field Service Kit with a 725 Wrist point used in Step 2.

If using a standard AC electrical outlet, use the SCS CTM051 Ground Pro Ground Integrity Meter. It measures ground impedance in accordance with ANSI/ESD S6.1 and ANSI/ESDA S20.20 standards. It can be used to verify that there is no voltage leakage between ground and hot. If an outlet is not Figure 4.

FSKL3RD PORTABLE FIELD SERVICE KIT This Field Service Kit provides a complete portable static-safe workstation for personnel working with electronics in the field. To stop static electricity from damaging electronic and telecommunications cards, a static safe work area is essential for field service technicians performing in-field repair or installation of cards.
