

When operating Huawei equipment, in addition to following the general precautions in this document, follow the specific safety instructions given by Huawei.



Only trained and qualified personnel are allowed to install, operate, and maintain Huawei equipment.

Local Safety Regulations

When operating Huawei equipment, you must follow the local laws and regulations. The safety instructions in this document are only supplements to the local laws and regulations.

General Requirements

To minimize risk of personal injury and damage to equipment, read and follow all the precautions in this document before performing any installation or maintenance.

Ensure that the instructions provided in this document are followed completely. This section also provides guidelines for selecting the measuring and testing devices.

Installation



The device (or system) must be installed in an access-controlled location.



The device must be fixed securely on the floor or to other immovable objects such as walls and mounting racks before operation.



When installing the unit, always make the ground connection first and disconnect it at the end.



Tighten the thumbscrews by using a tool after initial installation and subsequent access to the panel.



The device must be fixed securely on the floor or other reliable objects, such as the walls and the mounting racks before operation.



The device (or system) must be installed in an restricted access location.



A readily accessible disconnect device shall be incorporated in the building installation wiring.

Ground



Do not damage the ground conductor or operate the device in the absence of a properly installed ground conductor. Conduct the electrical inspection carefully.



The device (or system) must be connected permanently to the protection ground before an operation. The cross-sectional area of the protective ground conductor must be at least 16 mm2.

Power Supply



For DC-supplied model: The device applies to DC power source that complies with the Safety Extra-Low Voltage (SELV) requirements in IEC 60950-1 based safety standards.



Prepared conductors are connected to the terminal block, and only the appropriate AWG/Type of wire is secured with the lug terminals.



Short-circuit (overcurrent) protection of the device varies according to the building's installation. Ensure that a fuse or circuit breaker no larger than 80 VDC, 30A for DC-supplied model is used on the phase conductors (all current-carrying conductors).



To minimize the risk of fire, use only No. 26 AWG or larger telecommunication line cord.



Reinforced insulation or double insulation must be provided to isolate DC source from AC mains supply.

Human Safety



Do not operate the device or cables during lightning strikes.



To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telecommunication network voltage (TNV) circuits.



Move or lift the chassis by holding its lower edge. Do not hold the handles on certain modules such as power supply, fans, and boards because they cannot support the weight of the device.



Do not look into the optical port without eye protection.



Do not wear jewelry or watches when you operate the device.

Operator



Only qualified professional personnel are allowed to install, configure, operate, and disassemble the device.



Only the personnel authenticated or authorized by Huawei are allowed to replace or change the device of the parts of the device (including the software).



Any fault or error that might cause safety problems must be reported immediately to a supervisor.



Only qualified personnel are allowed to remove or disable the safety facilities and to troubleshoot and maintain the device.

Operation temperature



-40 to +50˚C.

1.1.2 Electrical Safety

High Voltage

The high voltage power supply provides power for the device operation. Direct or indirect contact (through damp objects) with high voltage and AC mains supply may result in fatal danger.



During the installation of the AC power supply facility, follow the local safety regulations. The personnel who install the AC facility must be qualified to perform high voltage and AC operations.



Do not wear conductive articles, such as watches, hand chains, bracelets, and rings during the operation.
