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.
Proposition 65 Warning (US Only)
State of California Proposition 65 Warning (US only)
WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
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
RFV01U-D2A Installation Manual v2.0 |

Preface
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.
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 module 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

Preface
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.
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

Chapter 1 Before Installation
Cautions for Installation
Observe the following safety instructions when installing the system. Installation should be 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.
With guardrails or fences, block open areas such as connecting parts, roof, and scaffold.
Install the system in the Restrict Access Area.
While Installing
While installation, ensure the following:
The system power must be cut off before installing.
Be careful not to damage or scratch the boards mounted on the system and the cables among the boards when the system is transported or installed.
Make sure the power switch of power supply is off when installing the system. Installing the system with power switch on may cause system damage or fatal human injury when cables are not correctly connected.
Make sure that worker wears protection gloves and goggles to prevent damage from debris while drilling holes in a wall or ceiling.
Do not wear accessories such as watches and rings to prevent electrical shock.
Never allow foreign substances to be inserted into unused ports by covering them with a cap.
To prevent foreign substances, outdoor air and moisture from entering the cable inlet (including cable gland and conduit), do the following:
- 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 silicon.
Keep a safe distance between the base station antenna and people.
