Issue 10 (2017-08-08) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 1 ETP4830-A1 Embedded Power User Manual 1 Safety Precautions Measure contact point voltage with a multimeter before handling a conductor surface or terminal. Ensure that the contact point has no voltage or the voltage is within the specified range. When installing or removing power cables, ensure that the corresponding circuits are disconnected to prevent electric arcs or sparks. If AC input power cables need to be routed from the top, bend the cables in a U shape outside the cabinet and then route them into the cabinet. Performing maintenance or replacing components may interrupt power to the loads if batteries are not connected or the battery reserve is insufficient. Ensure that the switches for primary loads are in the ON position and do not turn off the battery switch and the AC input switch at the same time. Cables stored at subzero temperatures must be stored at room temperature for at least 24 hours before they are laid out. Perform routine maintenance as described in this manual; replace faulty components at the earliest. After maintenance is completed, lock cabinet doors and seal cable holes to prevent rodents from entering the cabinet. 1.2 Electrical Safety Grounding When installing a device, install the ground cable first. When uninstalling a device, remove the ground cable last. Before operating a device, ensure that the device is properly grounded. Ensure that the ground cable is installed securely (the ground resistance should be less than 0.1 ohm). Inappropriate grounding may cause device damage and personal injury. AC and DC Power The power system is powered by high-voltage power sources. Direct or indirect contact (through damp objects) with high-voltage power sources may result in serious injury or death. Non-standard and improper operations may result in fire or electric shocks. Before making electrical connections, turn off the protection switch on the upstream device to cut the power supply. Before connecting the AC power supply, ensure that electrical connections are complete. Before connecting cables to loads or battery cables, check cable and terminal polarities to prevent reverse connections. Issue 10 (2017-08-08) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 2 ETP4830-A1 Embedded Power User Manual 1 Safety Precautions ESD To prevent electrostatic-sensitive components from being damaged by static from human bodies, wear a grounded electrostatic discharge (ESD) wrist strap or ESD gloves when touching circuit boards. When holding a board, hold its edge without touching any components, especially chips. Package boards with ESD packaging materials before storing or transporting them. Liquid Prevention Do not place the product in areas prone to water leakage, such as near air conditioner vents, ventilation vents, or feeder windows of the equipment room. Ensure that there is no condensation inside the product or equipment room. Ensure that no liquid enters the product. Otherwise, short circuits will occur and may result in serious injury or death. If any liquid is detected inside the product, immediately disconnect the power supply and contact the administrator. 1.3 Battery Safety Before installing, operating, or maintaining the batteries, read the battery manufacturer's safety instructions. Observe the safety precautions provided in this section, which are supplemental to the safety instructions provided by the battery manufacturer. Basic Requirements Avoid skin contact with battery electrolyte. Before handling batteries, wear goggles, rubber gloves, and protective clothing. When handling a battery, ensure that its electrodes always point upward. Do not tilt or overturn batteries. Before installing or maintaining batteries, switch off the battery circuit breaker or remove the battery fuse. Install batteries in a dry, clean, and ventilated environment that is free from sources of ignition. Do not expose batteries to sunlight or water. Ensure that the load-bearing capacity of the floor in the installation area is sufficient. Install additional supports if required. Secure battery cables to the torque specified in the battery documentation. Loose connections will result in excessive voltage drop or cause batteries to burn out in the case of excessive current. Ensure that battery cables do not come in contact with water. Battery Short Circuit Issue 10 (2017-08-08) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 3 ETP4830-A1 Embedded Power User Manual 1 Safety Precautions High short circuit currents or electric shocks can cause equipment damage, personal injury, or death. To prevent short circuit or electric shock, disconnect the batteries before performing any operation or maintenance. Flammable Gas Do not use unsealed lead-acid batteries. Lead-acid batteries emit flammable gas. Therefore, place and secure lead-acid batteries horizontally to prevent fire or corrosion. Store lead-acid batteries in a place with good ventilation, and take fire safety precautions. Battery Leakage High temperatures may result in battery distortion, damage, and electrolyte overflow. If the battery temperature is higher than 60°C, battery electrolyte may overflow. If the electrolyte overflows, wear goggles, rubber gloves, and protective clothing and absorb the leaking electrolyte using sodium bicarbonate (NaHCO3) or sodium carbonate (Na2CO3). Do not transport or move batteries if there is an electrolyte leakage. Battery Overdischarge After connecting the batteries, remove the battery fuse or turn the battery circuit breaker OFF and then power on the power system. This prevents battery overdischarge. After the power system is on, replace the battery fuse or turn the battery circuit breaker ON. 1.4 Cable Layout When routing cables, ensure that a sufficient distance exists between the cables and the DC busbar, shunt, and fuse. This prevents damage to the insulation layer of the cables. Route and bind signal cables and power cables separately. Ensure that cables meet the VW-1 testing requirements. Do not route cables behind the air exhaust vents of rectifiers in the cabinet. Ensure that all cables are securely bound. Issue 10 (2017-08-08) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 4 ETP4830-A1 Embedded Power User Manual 1 Safety Precautions 1.5 Mechanical Safety Hoisting Devices Do not walk under hoisted objects.
