Confidential

Lasers

The product is fitted with optic modules rated as Class 1 radiation-emitting devices under IEC/EN 60825-1. During installation, operation, and maintenance, never look into the end of an optical fiber directly or by reflection either with the naked eye or through an optical instrument. Do not operate equipment with exposed fiber connectors-cover these with fiber cables or blanking caps. Do not remove equipment covers during operation unless requested to do so in the documentation. Carry out normal safety precautions when trimming fibers during installation.

Manual Handling

Care should be taken when handling equipment. Give due consideration to the weight of the equipment, the physical capability of the individual(s) handling the equipment, and movements such as twisting, bending and stooping, which could lead to skeletal and muscular injuries.

Installation

Installation must be carried out by trained and competent engineers only. All relevant safety measures should be taken to ensure equipment is not connected to live power and transmission sources during installation. Equipment must be correctly installed in order to meet the relevant safety standards and approval conditions.

Each power feed to the unit requires a separate fused feed from the provided power supply. The cable between the power distribution point and the installed equipment must have a minimum cross-sectional area of 2.5 mm2.

damage to the system from a vibration or shock.

o Use an elevator to prevent accidents. However, if the system must be

carried by people, ensure there are enough people to carry the system.

 The system must not be shocked physically.

 The system should be protected from dust, moisture, and static electricity.

Page 32

Unpacking

Confidential

Chapter 2 Installing System

To unpack the items, ensure the following:

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

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

a place that does not interfere with working.

 Unpacked systems must be installed immediately. If immediate installation of

the systems is not planned, 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.

 Dispose by-products (packaging waste) in accordance with waste management

rules. Do not recycle the by-products.

Confidential

When cutting the cable after installation, ensure that the connector is disconnected.

The cable installation while the connector is connected to the system may cause contact failure, or damage to the assembled connector and the cable, due to cable tension or operator 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 the cable that interconnects rectifier, Main Ground Bar (MGB), backhaul device, and so on within the system, the cable path, length, and cable installation method must be inspected.

To inspect the cable path, ensure the following.

 A minimum cable length must be selected, so that the length does not affect

the cable installation and maintenance.

Page 73

 The cable must be placed in a location where the cable is not damaged by

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

Cable Cutting

Measure the exact distance after carefully checking the route, and cut the cable using a cutting tool.

To cut the cable, follow these guidelines:

 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 moisture, iron, lead, dust, or other

measures are taken to prevent damage to the cable, such as cable tray, ducts, and flexible pipe.

foreign material when cutting.

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

Cable Installation

This process involves running the cable along the cabling path to the target connector of the system or an auxiliary device. This is done after cable path inspection and cable cutting are completed.

To install the cable, follow these guidelines:

 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 the 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 ensure that the

minimum curvature radius specification is complied with.

 If the cable needs to be protected, use suitable protective cover such as PVC

channel, spiral sleeve, flexible pipe, and cable rack.

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

power cable to prevent electromagnetic induction.

The table below outlines the recommended minimum allowed cable bend radius for different types of cables:

Connector Attachment

This process involves assembling a connector to an installed cable or to a device on the site.

Follow these guidelines when attaching the connector.

 Ensure operator is fully aware of the connector assembly method before

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

 Ensure the cutting sections of the cable tie and the binding line are not exposed

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

 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 chance of contact-failure to occur in the connector connection due

Page 75

Chapter 3 Connecting Cables

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

Identification Tag Attachment

This process involves attaching a marker cable tie, a nameplate, and a label to both ends of a cable (connections to a connector) to identify the use of the cable and the cabling path.

Follow these guidelines when attaching an identification tag.

 When installing the cable outdoor, use relief engraving and coated labels 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 the tags.

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

contacts the equipment, connects a cable, or performs maintenance without connecting the ground cable, the system can be damaged or the worker may be injured due to static electricity and short circuit.

Confidential

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.

After completing cable installation, unused ports must be capped.

When installing, ensure not to overlap or tangle the cables. In addition, consider

future expansion. Install the DC power cable and the data transmission cable away from the AC power cable to prevent electromagnetic induction.

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

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

manipulating the circuit breaker of the rectifier, ensure to check the rectifier 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 get critically injured if the cable is connected in the wrong way.

Confidential

System

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

short-circuit through the cable. Ensure the power switch of 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 the operator installs the cable after cutting, there may be length difference among the core wires at the end of the cable because of cable curvature. This may result in poor contact after the cable is connected to the power port.

If you turn the power on and off rapidly (within 1 s), the counter electromotive

force caused by cable inductance can damage the system.

Connecting more than one power cable together may increase power loss. It must be verified that the rectifier or the power distributor has an output voltage

within the specified system input range before the power line is connected.

Be sure to comply with the maximum length of use for the power cable. If the

length of the power cable exceeds the maximum length of use, it may cause fire,
