from contact of power cable with conductors, causing fires or eye injury.

z Power must be switched off before installation and removal of power cable.z Before connecting cable, make sure that the cable and cable tag to be used

should match actual installations.3.3 Tools

Warning:

High-voltage and AC operations call for special tools instead of general-purpose or makeshift tools.

3.4 Drilling Holes

Warning:

Unauthorized drilling on the cabinets is strictly prohibited. Improper drilling may damage the connections

and cables inside the cabinet, and the metal filings resulting from the drilling may cause short-circuit of

circuit board if the fillings fall into the cabinet.

z To drill on the cabinet, insulated gloves must be worn and the cables inside the

cabinet must be removed.

z The installation personnel should protect their eyes properly when drilling. Flying

metal filings may hurt ones eyes.

z Prevent metal filings from falling into the cabinet.z Improper drilling will deteriorate the electromagnetic shielding performance of the

cabinet.z

After drilling, remove all the metal filings immediately.

3.5 Thunderstorm

Danger:

High-voltage and AC operations and operations on steel towers and masts are strictly prohibited in

thunderstorms.

Thunderstorms can generate powerful electromagnetic field in the atmosphere.

Therefore, equipment should be grounded properly in order to prevent the equipment

from being thunderstruck.

3.6 Electrostatic

Caution:

Static electricity generated on human body may damage the electrostatic-sensitive parts on the circuit

board, such as large-scale integrated circuit (IC).

z In dry climate, the electrostatic charge carried by human body may be up to 30

kV, which will remain on the human body for a rather long period of time. The

operators contact with the component and the electric discharge will cause

damage to the component.

z Before contacting any equipment, hand-held plug-in boards, circuit boards and

IC chips, put on anti-static wrist belts with one end well grounded so as toprevent sensitive parts from being damaged by static electricity on the human

body.z Before operators touch the board or module, they should discharge the

electrostatic in their body. That is, before the operator touch a board or a module,

he must wear anti-static wrist strap. The connecting line between wrist and

grounding point should connect in series with a resistance greater than 1M: to

protect people from being accidentally shocked. The resistance value greater

than 1M: is rather low in terms of electrostatic voltage discharging. The

anti-static wrist strap should be checked regularly. It is strictly prohibited using

other cable to replace the cable of anti-static wrist strap.


22/209

z Electrostatic-sensitive board or module should not be in contact with the object

with electrostatic or the object that may easily generate electrostatic.

z Electrostatic-sensitive board or module can only contact the quality discharging

material, such as the anti-static packing bag. The board in stock or in the courseof transportation should be packaged with anti-static packing bag.

z Before the measurement device is connected to boards or modules, it should

firstly discharge its electrostatic; that is, the measurement device should be

grounded in the first place.

z The boards or modules should not be placed near strong DC magnetic field, say,

near the cathode ray tube of the scope. The safety distance should be outside of

10 cm range at least.

z The damage caused by electrostatic is accumulative in effect. If the damage is

slight, the component will not malfunction. However, as the time of damage

increases, the components may suddenly fail. The electrostatic discharging

damage on the component is of two types: explicit damage and implicit damage.

Implicit damage is not shown when the damage occurs, whereas the component

may become vulnerable and easily get damaged under the condition of

over-voltage and of high-temperature.The correct way of wearing anti-static wrist strap is shown in Figure 1.

3.8 Leakage Current

Warning:

To avoid the occurrence of large leakage current, the equipment must be grounded before it is

connected with power supply.

Before connecting the AC input power supply, the operation and maintenance

personnel should first connect the protection-grounding terminal of the equipment

housing with the earth. The purpose of doing this is to avoid the electric shock on

human body result from leakage current, which is usually caused by the EMI wave

filter earth capacitance of the equipment AC power supply input terminal or the Y

capacitance of the primary power supply.

3.9 Environment with Flammable Air

Danger:

The equipment should not be placed in the environment where flammable, explosive air or smog exists.

4.4 High Temperature

Caution:

Excessively high temperature of batteries will cause deformation and damage of batteries and spillover

of acid liquid.

z When the temperature of battery is over 60C, check whether there is spillover of

acid liquid.

z In case of acid liquid spillover, please handle the acid spillover in time.

4.5 Acid Liquid

Caution:

In case of acid liquid spillover, make sure that such spillovers are absorbed and neutralized.

z To move leaking batteries, mind the damages liable from the acid liquid. Once

acid liquid is found to have spilt over, absorb and neutralize it with the following

materials.z Bicarbonate: NaHCO3

z Barilla: Na2CO3

z Soda: Na2CO310H2O

z Consult with battery manufacturers as regards materials used to absorb and

neutralize acid liquid.4.6 Battery Replacement

Warning:

Operation and maintenance personnel should not replace the batteries of prescriptive model with that of

different model; otherwise, the explosion danger of the batteries may incur.

5 Microwave and Magnetic Field

5.1 Introduction

The equipment antenna in service will generate electromagnetic radiation. Standing

too close to the antenna is against the safety codes. The equipment can only be

installed and maintained by trained professional personnel. The radiation design of

the equipment should meet the IEEE C95.1-1991 recommendation. When working

near the full-power transmitting antenna, one should read the following safety working

requirement.

5.2 Definition of the Environment

The uppermost level limit of the environment that can be exposed to radio magnetic

radiation is of two kinds: one is "controlled environment" and the other is "uncontrolled

environment" with less radiation.

z Controlled environment

"Controlled environment" refers to a certain location where the personnel who enter

the area are aware of the potential threat of exposing themselves in the radio

frequency radiation environment. The magnetic field level of the area is higher than

that the level of "uncontrolled environment" but no greater than that of "controlled

environment level" listed in the table.

z Uncontrolled environment

"Uncontrolled environment" refers to a certain location where the personnel who enter

the area are not aware of the potential threat of exposing oneself in the radio

frequency radiation environment, and they cannot be in control of the environment

where they are situated. This location may include living environment or working

environment. The magnetic field level of the location cannot be greater than the

uppermost level that can be exposed in the "uncontrolled environment".

5.3 Minimal Distance Formula

The following content introduces how to calculate the minimal safety distance. The

formula is used for calculating the minimal safety distance apart from all types of

antenna.

rmin=N10 10

G-LP

4 WOUT

The respective element in the formula is explained in the following:


27/209


12

Rmin is the minimal safety distance, and its unit is meter.

N is the number of frequency carriers.

Pout is the output power of the frequency carrier, and its unit is W.

L is the loss from transmitting party to the receiving party, and its unit is dBm.

G is the antenna gain, and its unit is dBm.

W is the greatest field power density permitted, and its unit is W/m2.

In the uncontrolled environment, the greatest field power density permitted is f/150, in

which f is the frequency, whose unit is MHz. Its tested value is the mean value

measured when the testing time is over 30 minutes. In the controlled environment, the

greatest filed power density permitted is f/30, and its tested value is the mean value

measured when the testing time is over 6 minutes.

Upon the above formula, the minimal safety distance on the axial line of the antenna

field is shown in Table 2.

Table 2The typical minimal safety distance

Frequency f (MHz) 1800

Frequency output power Pout (W) 40

Loss from the transmitting party to the receiving party L (dBm) 5.5

Antenna gain G (dBm) 18

Power density/controlled environment W (W/m2) 60

Uncontrolled environment rmin (m) 3.1

Controlled environment rmin (m) 1.4

5.4 Operation Codes

Warning:

When operating on the high intensity radio frequency signal equipment, mind that the high-intensity

microwave is detrimental to human health.

z When installing and maintaining the antenna at local end on steel tower and

mast on which multiple transmitter antennae are installed, proper coordination

work should be made in advance and the transmitter of the antenna should be

shut down.


28/209


13

Warning:

The operation of installation and maintenance around the area where the antenna is in service should be

kept away from the antenna for a distance far enough.

z It is strictly prohibited to screw off the transmitter output feeder or antenna feeder

cable plug while the transmitter is in operation.

z When it is required to screw off the feeder cable plug or to work in the nearby of

the transmitting antenna, the concerned transmitter should be powered off.

6 Laser

Warning:

The laser beam inside optical fibers may do harm to the eyes.

In the installation and maintenance of optical fibers, keep your eyes away from, or

avoid direct look at, the optical fiber outlet.

7 High Temperature

Warning:

It is unavoidable that the temperature of some equipment parts is rather high. Please do not touch the

surface freely, or the scalding may occur.

z When the equipment is running in the tropical environment, the temperaturebenchmark of the parts is 45C and the maximal range of temperature rise

allowed is 30C in the normal working condition. When fault occurs,the maximal

range of temperature rise allowed is 55C. So when the parts work at the high

temperature of 45C in the normal working condition, their highest temperature

should not exceed 75C, and when fault occurs, the highest temperature should

not exceed 100C.

z The temperature for radiator of the transmitter RF power amplifier and the power

supply radiator, for instance, can reach above-mentioned high temperature.
