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.

 Tighten the thumbscrews by using a tool after initial installation and subsequent access

to the panel.

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

16mm2.

 The device must be fixed securely on the floor or other reliable objects, such as the walls

and the mounting racks before operation.

 When installing the unit, always make the ground connection first and disconnect it last

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.

 This device relies on the building’s installation for short-circuit (overcurrent) protection.

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).

 For this device, a readily accessible disconnect device shall be incorporated external to

the equipment

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

cord.

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.

 Reinforced insulation or double insulation must be provided to isolate DC source from

AC mains supply.

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.

 Ensure that the instructions provided in this document are followed completely. The

document also provides guidelines in selecting the measuring and testing device.

1.2 Equipment Safety

1.2.1 Electricity Safety

Thunderstorm

During thunderstorms, the electromagnetic field generated in the thunderstorm area may

damage the electronic parts. To prevent damage to the device during lightning, ground the

device properly.

High Electrical Leakage

If the "high electrical leakage" tag is present on the power terminal of the device, you must

ground the device before powering it on.

Fuse

If a fuse is to be replaced, the new fuse must be of the same type and specifications.

1.3 Electromagnetic Field Exposure

Introduction

The Base Transceiver Station (BTS) emits Radio Frequency (RF) radiation. Follow the local

safety regulations when installing and operating the BTS to avoid radiation hazard.

Guidelines on Limiting Exposure to Electromagnetic Fields

There are a number of international regulations, standards, and guidelines for exposure to

electromagnetic fields. Some European countries have adopted the recommendation of the

council of the European Union (1999/519/EC), released on July 12, 1999, focusing on the

hazards of exposure to electromagnetic fields. The recommendation is based on the guideline

published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

Location of Base Station Antennas

Base station antennas, the source of the radiation, are usually mounted:

 On freestanding towers, with a height up to 30 m

 On a tower on the top of buildings

 To the side of buildings, on rare occasions

Generally, the antenna cannot be located in a position lower than 10 m. The energy usually

forms a horizontal main beam and is slightly tilted downwards. The remaining energy forms

into weaker beams on both sides of the main beam. The main beam, however, does not reach

the ground if the antenna is around 50–200 m away from the ground.

The highest level of emission would be expected in close vicinity of the antenna and in line of

sight to the antenna.

Exclusion Zones

The requirements for exclusion zones are as follows:

 The antenna should be properly located to prevent the public from accessing the area

where the RF radiation exceeds the previously mentioned limits.

 If areas with excessive RF radiation are accessible to the operation and maintenance

(O&M) personnel, ensure that they know the source of radiation and can power off or

shut down the transmitters before entering high radiation areas. In addition, such areas

must be confined within a distance of 10 m from the antennas.

 Each exclusion zone should be defined by a physical barrier and by a recognizable sign

warning the public or O&M personnel.
