Preface
Personal and Product Safety
This product safety information includes European directives, which you must follow. If these do not apply in your country, please follow similar directives that do apply in your country.
Electrical
The product is designed to operate from a -48 V DC supply and is therefore classified as Safe Extra Low Voltage (SELV) equipment.
All structural parts are grounded and all input and outputs have built-in isolation from the network. All input and output ports that connect to external power sources are designed to meet relevant national safety requirements.
The product contains hazardous energy levels as defined by EN 60950. Care must be taken when maintaining this equipment as injury to personnel or damage to the equipment could result from mistakes. Maintenance should only be carried out by trained and competent engineers who are familiar with the relevant procedures and instructions.
Lasers
The product is fitted with optic modules rated as Class 1 radiation-emitting devices under 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.

Preface
Rack-mountable equipment must be placed in a standard 19-inch rack and secured with the appropriate fixings as detailed in the installation manual.
Maintenance
Maintenance must only be carried out by a suitably trained and competent technician. All safety instructions must be carefully observed at all times. Equipment covers should not be removed while live power and transmission is connected unless in a controlled environment by trained technicians.
Fire
The product is powered from a -48 V DC supply. To protect against fire, the equipment is fused.
Environment
The product must be operated in an environment with the specified relative humidity and ambient temperature ranges.
Keep all liquids away from the equipment as accidental spillage can cause severe damage.
Cooling
The product cools down by its own set of cooling fans housed in a fan module. Each fan module detects a fan that is not operating normally. LEDs on the front panel of the fan tray provide an alarm indication in the event of fan failure.
In the event of fan failure, take urgent remedial action to restore full cooling capacity.
Take appropriate measures to ensure that fan modules do not start spinning during repair and maintenance procedures.
Anti-Static Precautions
The circuit boards and other modules in the product are sensitive to and easily damaged by static electricity. If any card or sub-assembly is removed from the unit, the following anti-static precautions must be observed at all times:
Service personnel must wear anti-static wrist straps.
Circuit boards and sub-assemblies must be placed on ground conductive mats or in conductive bags.
All tools must be discharged to ground before use.
The anti-static wrist strap and cord must be checked at regular intervals for their suitability for use.

Preface
Grounding
To comply with EN 60950, the equipment must be connected to a safety grounding point via a permanent link. Grounding points are located on the product for this purpose. Always connect the ground cable before fitting other cables. The product must remain grounded continuously unless all connections to the power supply and data network are all removed.
If equipment is grounded through a cabinet or rack, make sure it is done so properly according to the installation instructions.
Power Supply Connection
The equipment is designed to be powered from a -48 V DC supply. Power connections and installation of associated wiring must be carried out by a suitably qualified technician.
Only devices that comply with all relevant national safety requirements should be connected to the unit's power supply inlets. Other usage will invalidate any approval given to this equipment.
Connection of this equipment to devices that are not marked with all relevant national safety requirements may produce hazardous conditions on the network.
When the power supply is obtained by a rectifier/safety isolation transformer, the supply must meet the requirements of EN 60950 providing double/reinforced insulation between hazardous voltages and SELV/TNV circuits. Any battery must be separated from hazardous voltages by reinforced insulation.
Indirect Connection
Before indirectly connecting any equipment to another device through a shared power supply, ALWAYS seek advice from a competent engineer.
Devices that are not marked according to the relevant national safety standards may produce hazardous conditions on the network.
Product Disposal
To reduce the environmental impact of products, Samsung has joined WEEE compliance activities.
The WEEE symbol on the product indicates that the product is covered by the European Directive 2002/96/CE for the disposal of Waste Electrical and Electronic Equipment (WEEE). This means that the product should be disposed of separately from the municipal waste stream via designated collection facilities appointed by the government or the local authorities. This will help prevent potential negative consequences for the environment and human health. Please check the terms and conditions of the purchase contract for information about correct disposal.

Chapter 1 Before Installation
Cautions for Installation
Observe the safety instructions described in this section when installing the system.
Installation should be done in accordance with the applicable local electric codes.
Before Installing
Before starting the installation, ensure the following:
Post warning signs in areas where high-voltage cables are installed.
Post ‘off limit’ signs in areas where accidents are most expected.
Use guardrails or fences to block open areas such as ditches, open roof areas, and scaffolds.
Install the system in the restricted access area.
While Installing
During installation, ensure the following:
The system power must be cut off before installing.
Ensure that the power switch of the power supply is off when installing the system. Installing the system with power on may cause system damage or fatal human injury when connecting or disconnecting cables.
Ensure that workers wear protection gloves and goggles to prevent injury from debris while drilling holes in a wall or ceiling.
Do not wear accessories such as watches and rings to prevent electrical shock.
Cover unused ports with a cap. This prevents foreign substances from entering into the unused ports.
To prevent foreign substances, outdoor air, and moisture from entering the cable inlet (including cable gland and conduit), finish the inlet as follows:
-Unused inlet: Use the hole finishing materials including cap and rubber packing.
-Cable-installed inlet: After cable installation, block any space in the inlet with tape, compressed sponge, rubber packing, and silicone.
When operator installs the MMU, the MMU must be within the protective angle (left/right side 45° each from the central axis) to prevent the MMU from lightning damage.

Keep a safe distance (1.3m) between the base station antenna and people.
Do not co-locate nor operate in conjunction with any other antenna or transmitter for the protection of general public from exposure to radio frequency electromagnetic field
After Installing
After installation, remove any debris produced during the work and clean up the installation site.
In the system, the laser beam light runs through the optical cable. The workers must handle the optical cables with care as the laser beam can seriously damage the eyes.
Ensure that the workers do not damage installed cables while cleaning the system.
While cleaning the power supply device, take precaution that the device does not come in contact with foreign objects that may cause power failure.

Transporting and Unpacking
This section describes how to transport the items to the installation place and provides the procedure to unpack cabinets and other components.
Bringing in Items
Ensure the following at each stage of transportation of the items:
Before moving a system, check storage place for the system and remove obstacles in advance.
When carrying the system:
o Fasten the system firmly to the transport vehicle or carrier to prevent 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.
Unpacking
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.
