Electrical Safety Instructions The following are the electrical safety instructions about tools, high voltage, power cables, holes and lightning: Tools Use special tools rather than common tools for high-voltage and AC operations. High Voltage ： Danger： High voltage is hazardous. Direct or indirect contact with high voltage or main supply using a wet object could result in death. à Strictly follow local safety rules to install AC power devices. à Installation staff must be qualified for performing high-voltage and AC operations. à Do not wear any watch, hand chain, bracelet, ring or any other conductive objects during such operations. à Prevent moisture from accumulating on the equipment during operations in a damp environment. Power Cable 1-3 SJ-20101019140047-002(R1.1)|25/12/2010 ZTE Proprietary and Confidential ZXSDR RSUC User Manual ： Warning： Never install or uninstall power cables while they are live. Otherwise, the power cable, when contacting a conductor, may result in sparks or electric arc causing a fire or even damage to eyes. à Make sure of shutting off power supply before installing or disconnecting a power cable. à Before connecting the power cable, make sure that the connecting cable and its label are appropriate for the actual installation requirements. Drilling Holes ： Warning： It is not allowed to drill chassis holes without permission. à Unqualified drilling could damage wiring and cables inside the chassis. Additionally, metal pieces inside the chassis created by the drilling could result in a short circuit. Use insulation protection gloves and first move cables inside a chassis away when drilling is necessary on a chassis. à Protect eyes during drilling as dust or flying debris may damage eyes. à Clean any debris in time after drilling. Lightning ： Danger： Do not perform high-voltage, AC, iron tower or mast operations in a thunderstorm. Thunderstorms would give rise to a strong electromagnetic field in the atmosphere. Therefore, the equipment must be grounded and protected in time against lightning strikes. Antistatic Safety Instructions ： Electrostatic： Static electricity produced by human body can damage static-sensitive components on circuit board, such as large-scale integrated circuits. Friction caused by human body activities is the root cause of electrostatic charge accumulation. Static voltage carried by a human body in a dry environment can be 1-4 SJ-20101019140047-002(R1.1)|25/12/2010 ZTE Proprietary and Confidential Chapter 1 Safety Description up to 30 kV, and can remain there for a long time. An operator with static electricity may discharge electricity through a component when he/she touches the conductor and causing damage. Wear an antistatic wrist strap (the other end of wrist strap must be well grounded) before touching the equipment or holding a plug-in board, circuit board, Integrated Circuit (IC) chip or other devices, to prevent human static electricity from damaging sensitive components. The antistatic wrist strap used must be subject to regular check. Do not replace the cable of an antistatic wrist strap with any other cables. Do not contact static-sensitive modules with any object that easily generates static electricity. For example, friction of package bag, transfer box and transfer belt made from insulation plastic may cause static electricity on components. Discharge of static electricity may damage components when they contact a human body or the ground. Modules should only contact materials such as an antistatic bag. Keep modules in antistatic bags during storage and transportation. Discharge static electricity of the test device before use, that is, ground the test device first. Do not place the module near a strong DC magnetic field, such as the cathode-ray tube of a monitor. Keep the module at least 10 cm away. Hoisting Heavy Objects ： Warning： When hoisting heavy objects, ensure that nobody is standing or walking under the hoisted object. Ensure the hoister can meet hoisting requirements when disassembling heavy equipment, or moving and replacing equipment. The installation personnel must be duly trained and qualified for hoisting operations. Hoisting tools must be inspected and complete before service. Make sure that hoisting tools are fixed firmly on a sufficiently secured object or wall before the hoisting operation. Give brief oral instructions during hoisting operations to prevent any mishap. Unplugging/Plugging a Module Never plug a module with excessive force, to ensure that the pins on the backplane do not get deformed. Plug the module right into the slot and make sure module circuit faces do not contact each other lest any short circuit may occur. Keep hands off the module circuit, components, connectors and cable trough when holding a module. 1-5 SJ-20101019140047-002(R1.1)|25/12/2010 ZTE Proprietary and Confidential ZXSDR RSUC User Manual Rack Mount Safety Instructions Rack Mount Instructions - The following or similar rack-mount instructions are included with the installation instructions: Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
