Personal and Product Safety
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 optical 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 10 mm2.
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 is natural convection cooling type.
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.
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

Confidential

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

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 main 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 the 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 entering into the
unused ports.
To prevent foreign substances, outdoor air, and moisture entering into the cable
inlet (including cable gland and conduit), finish the cable 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 the
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.
