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 and 230 V AC.
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 UL 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.
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 and 230 V AC 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.
Anti-Static Precautions
Confidential
Preface
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 UL 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.
Power Supply Connection
Power connections and installation of associated wiring must be carried out by a
suitably qualified technician.
The antenna(s) must be installed such that a minimum separation distance of at
least 300 cm is maintained between the radiator (antenna) and all persons at all
times.

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.
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.
