SJ-20110104194923-001|2013-6-20(R1.0) LEMKO Proprietary and Confidential 3-3 Antistatic Chapter 2 Product Installation The friction caused by human activities is the reason to produce the accumulation of electrostatic charge. In dry climates, electrostatic voltage carried by the human body can be accumulated up to 30 kV, which will be kept in the body for couple of hours. Operators carrying electrostatic charge will be discharged through the device, causing equipment damage. To avoid damaging sensitive components by human static electricity, before touching the devices, such as boards, circuit boards, IC chips, operators should wear antistatic wristband, and make sure the other end of wristband touches the ground. To protect people from accidental electric shock, a resistance over 1 M should be added between the antistatic wristband and the ground. The antistatic wristband should be inspected periodically. Do not replace the electric wires on the wristband by any other unqualified ones. Those electrostatic sensitive boards or modules should not have any contact with the objects of electrostatic charge or which carries static electricity easily. For example, friction between the packages of insulating materials and transmission belt could make the components carrying static electricity. Damages may happen when it is discharged by contacting human body. Those electrostatic sensitive boards can be only contacted with qualified discharged materials, such as antistatic bag. Equipment components need to be stored or transported in the antistatic bags. Before the testing equipment is wired with boards or modules, it should be connected to ground for discharging. Do not place the boards or modules near strong DC magnetic field. For example, those monitors with Cathode-ray tube, safety distance is over 10 cm. Caution!

Electrostatic charge produced by human body will damage the electrostatic sensitive components on the circuit board, such as Integrated Circuit (IC), etc. Lifting Weights The adequate facilities with lifting capacity must be used for assembling, moving or replacing the heavy equipments. The staff for lifting operations is required to have qualified training. Lifting tools must have periodic inspection, and must be used when it is a complete tool kit. Ensure that the lifting tool can be firmly fixed on the fixture or load-bearing wall before any lifting operations. Use simplified commands to prevent misoperation. SJ-20110104194923-001|2013-6-20(R1.0) LEMKO Proprietary and Confidential 3-4 LMKT RL1F22 User Manual Warning!
