Unpacking and Transporting

This paragraph describes the work to unpack cabinets and other components and

transport them to the place to be installed.

Bringing in Items

Bring in items, taking care of the followings:

 When carrying a system, fasten the system firmly to the transport vehicle or

carrier to prevent a damage to the system for a vibration or shock.

 When carrying system, use a lift to prevent accidents. However, if the system

must be carried by people, enough people are required to carry the system.

 Before moving the system, check the storage place for the system and remove

obstacles in advance.

 While moving system, the system should not be shocked physically and

damaged caused by dust, moisture, and static electricity.

Unpacking Items

The procedure to unpack items is as follows:

 The packing items must be packed until they reach the installation place.

 The items are classified in accordance with each job specification and stored

on a place that does not interfere with working.

 Unpacked systems must be installed immediately. If not installed immediately,

the systems must be stored in the installation place temporarily.

 Unpack only external packing, leaving the internal packing in unpacked status.

 Unpack the inner packaging after each system is placed on its installation

location.

 Scrap by-products (packaging waste) in accordance with the rule. Do not

recycle the by-products.

Guidelines for Cable Connections

The procedure for cable connections is as follows:

Figure 31. Cable Connection Procedure

When cutting the cable after installation, make sure that the connector is

disconnected. Installation of the cable with the connector connected to the system

may cause contact failure or damage to the connector assembled to the system and

the cable due to cable tension or the operator’s mistakes.

The sequence of cable cutting and installation of the cable workflow can be changed

depending on the field situation such as ‘cutting after installing’ or ‘installing after cutting’.

Cable Path Inspection

When installing a cable that connects between the rectifier, Main Ground Bar

(MGB), and backhaul device, and so on within the system, the cable path, length

and the cable installation method, and so on must be inspected.

Follow these guidelines when inspecting the cabling path.

 A minimum cable length must be selected provided that it does not affect the

cable installation and maintenance.

 The cable must be placed in a location where it will not be damaged by

external factors (power line, flooding, footpaths, and so on).

 In areas where the cable may be damaged by external factors, ensure that

measures are taken to prevent damage to the cable (cable tray, ducts, flexible

pipe, and so on).

Cable Cutting

Measure the exact distance, carefully checking the route, and cut the cable using a

cutting tool.

Follow these guidelines when cutting the cable.

 Cut the cable to the length determined in the Cable Path Inspection step.

 Use a dedicated cable cutting tool.

 Cut the cable at right angles.

 Be careful to keep the cable away from any moisture, iron, lead, dust, or other

foreign material when cutting.

 Remove any foreign material attached to the cable using solvent and a brush.

Cable Installation

Cable installation involves running the cable along the cabling path to the target

connector of the system or an auxiliary device after cable path inspection and cable

cutting have been completed.

Follow these guidelines when installing a cable:

 Be careful not to damage the cable.

 If the cable is damaged, cut out the damaged section before installing, or

replace the cable.

 Run the cable so that it is not tangled. In particular, when installing a cable

from a horizontal section to a vertical section, be careful not to reverse the

upper and lower lines of the cable.

 Always use the maximum curvature radius possible, and make sure that the

minimum curvature radius specification is complied with.

 If the cable needs to be protected, use for example, a PVC channel, spiral

sleeve, flexible pipe, cable rack, and so on.

 Install the DC power cable and data transmission cable away from the AC

power cable to prevent electromagnetic induction.

※ If the allowed cable bend radius is specified by the manufacturer, comply with the bend radius specified.

Cable Binding

Cable binding involves fixing and arranging an installed cable using binding

thread, cable ties, binding wire, and ram clamps, and so on.

Follow these guidelines when binding a cable.

 Be careful not to damage the cable during binding.

 Use appropriate cable binding tools according to the target location (indoor or

outdoor, and so on) and the type of the cable (power supply cable, optical

cable, feeder line, and so on).

 Do not let the cutting section of a cable tie and binding line, and so on be

exposed to the outside. This may cause damage to cables or personal injury.

Make sure that the cutting sections of cable ties and binding lines, and so on

are not exposed to the outside.

 Cut off the remainder of the cable thread by leaving about 50 mm of extra

length to prevent the knot from easily getting untied.

 If there is a danger that contact failure may occur in a connector connection

due to tension, bind the cable at the closest location to the connector.

Connector Attachment

Connector attachment involves assembling a connector to an installed cable or to a

device on the site.

Follow these guidelines when attaching a connector.

 Make sure operator is fully aware of the connector assembly method before

assembling a connector. Assemble the connector in accordance with its pin

map.

 Each connector has a hook to prevent its core positions from being changed.

Chapter 3 Connecting Cables

RFD01F Series Installation Manual v1.0 42

 Check the corresponding grooves before connecting a connector to another

connector.

 Use a heat shrink tube at a connector connection for cables that are installed

outdoor, such as feeder lines, to prevent water leakage and corrosion from

occurring at the part exposed to the outside.

 Connect each cable of the connector assembly in a straight line.

 Be careful when connecting a cable so that contact failure does not occur at a

connector connection due to tension.

Identification Tag Attachment

Identification tag attachment involves attaching a marker cable tie, nameplate, and

label, and so on to the both ends of a cable (connections to a connector) to identify

its use and cabling path.

Follow these guidelines when attaching an identification tag.

 When installing a cable outdoor, use relief engraving and coated labels, and so

on to prevent the markings from being erased.

 Since the form and attachment method for identification tags are different for

each provider, consult with the provider before attaching them.

When connecting the cables, always connect the ground cable first. If worker

contacts the equipment, connect a cable or perform maintenance without

connecting the ground cable, the system can be damaged or a worker may be

injured due to static electricity and short circuit.

When performing cable work for the system, proceed with the ground work before

any other work to prevent errors occurring due to static electricity and other reasons.

When installing, take care not to overlap or tangle the cables; also, consider future expansion.

Install the DC power cable and data transmission cable away from the AC power cable to

prevent electromagnetic induction.

Make sure the work is done by personnel properly trained for the cabling job.

Grounding

Grounding is the process of operating an electronic system (for example. power

supplying system, communication system, and control system) stably from a

lightning, transient-current, transient-voltage and electric noise and of preventing

injury from electric shock.

Ground equipment minimizes the electrical potential of the electronic device to

that of the ground, which is zero electrical potential, so that it can prevent the

device from occurring electrification.

Connect the ground cable first. In cabling, the connection of cables without the

connection to the ground cable may cause damage of the equipment or bodily

injury to personnel.

The purposes of the ground construction are as follows:

 To prevent human life and the system from over-current, over-voltage, and

lightning

 To provide a discharge path for surge voltage generated by lightning and

power switch

 To protect the system from static electricity

 To eliminate or minimize the high-frequency potential in the system housing

 To provide a conductor for the balance and stability of high-frequency current

 To stabilize the potential of the circuit against the ground

Power Cabling

The power supply device consists of the following elements:

Figure 35. Power Equipment Elements

Since power is applied to the system where the power cable is connected by

manipulating the circuit breaker of the rectifier, be sure to check the rectifier’s

breaker is turned off (open) before connecting the power cable to the power

connector. If the system is installed while the circuit breaker is on, the worker may

be critically injured as soon as the cable is connected in the wrong way.

Handling the power cable incorrectly may damage the rack or cause an electric

short-circuit through the cable. Ensure the power switch on the rectifier or the system

is turned off before handling the power.

The fasteners for power cable must be tightly secured to prevent electrical accidents.

The heat-resistant temperature of the power cable should be 90°C or more.

Install the power cable to the power port of the system by considering the radius of

curvature of its cable specification and then cut the cable. If operator installs the

Checking RF Cable Connection

After connecting the RF cables, perform the continuity test and feeder cable return

loss to check if the RF cable is changed and measure VSWR of antenna and RF

cable.

Measure all cables of section ①~②. The measured VSWR should be the

specification value or less. If the VSWR exceeds the specification value,

disassemble the connector and measure each section separately.

If the VSWR value for minimum cable bend radius and length of RF cable is not

applied, system may not work properly because RF signals cannot transmit or

receive smoothly. So, the VSWR value for minimum cable bend radius and length

of RF cable must be checked and applied.

When measuring VSWR, if operator opens the antenna port when the transmission

output is not completely off, a spike signal may flow into the reception path, which

may cause damage to LNA. Make sure the transmission output is completely off

when measuring VSWR.

When RF cable connection integrated RET signal and DC power is applied using

ANT0 port of RRU, RET cable should be installed separated from RF cable to RF

Antenna.

Depending on the supplier or manufacturer of antenna/arrestor the connector type may be

different. Also, the detail specifications of a connector may be different depending on cable

type even for the same connector type. Therefore, check the detail specifications of a

connector before preparing parts.

inspection checklist actually at a site where the system is installed.

The inspector must record the results onto the inspection checklist during or after

filed inspection.

Sharing Inspection Results and Taking Corrective Actions

The inspector must share the inspection results (inspection checklist/corrective

actions) with an installation operator and, the installation operator must take the

corrective actions if necessary after reviewing the requirements.

Checking the Results of Corrective Actions

The inspector must check if the corrective actions are properly taken. If they are

not sufficient, the inspector must ask the installation operator to take the corrective

actions again.

Sharing the Results of Corrective Actions and Preparing Preventive Plan

After the corrective actions are all completed, the inspector must share the results

with the installation operator and relevant departments and prepare a preventive

plan to prevent the same or similar problems from re-occurring.
