Never connect or disconnect any hot power cables. At the instant when power cables touch conductors, electric sparks or arcs may occur, which may cause fire or eye injury. Turn off the power supply before installing or removing a power cable. Make sure the cables and the cable labels match the practical installation conditions before connecting them. Warning! Do not drill any holes on the cabinet on your own. Improper drilling may damage the wiring and cables inside the cabinet and the metal scraps produced during the drilling will cause short circuits in the circuit boards if they enter the cabinet. Static Electricity Caution! The static electricity generated by human body can damage the electrostatic-sensitive components on the circuit board, such as the large scale integrated circuit (IC). Accumulated electrostatic charges (ESC) derive from friction created by human body movements. In a dry environment, the static voltage carried by a human body can be up to 30 kV, and can remain in the human body for a long time. When an operator who carries static electricity touches a component, he will discharge electricity through the component, thus damaging the component. Before touching any equipment or holding the board, circuit board, and IC chip, wear the antistatic wrist strap and make the other end of it be well grounded. This helps avoid damaging electrostatic-sensitive components by the static electricity of human body. 4-3 SJ-20110104194923-001|2011-01-19(R1.0) ZTE Proprietary and Confidential ZXSDR R8882 L268 User Manual Laser Warning! Do not gaze at the laser beam from the optical transceiver or inside the optical fiber; otherwise, your eyes may be damaged. High Temperature Danger! The surface temperature of some devices is quite high, so do not touch them to avoid a scald injury. Hot Surface No-Touching! Temperatures exceeding the limits are permitted provided that the following conditions are met: – unintentional contact with such a part is unlikely, and - the part has a marking indicating that this part is hot. It is permitted to use the (IEC60417-5041 (DB:2002-10)) to provide this information. symbol Hoisting Heavy Objects Warning! Do not walk about right under the boom and the hoisted objects when they are being hoisted. When disassembling heavy equipment, or moving and replacing equipment, make sure facilities with proper hoisting capability are in place. The personnel that hoist the equipment should have received necessary training and acquired the corresponding qualification, and the hoisting tools should have been checked and be complete. 4-4 SJ-20110104194923-001|2011-01-19(R1.0) ZTE Proprietary and Confidential Chapter 4 Product Installation Make sure that the hoisting tools are fixed firmly to a fixture or a wall that can bear the weight for the hoisting.
