Safety instructions:
Caution Statements
Product inspection - Inspect the equipment
for shipping damage. Should any damage be
discovered, immediately le a claim with the carrier.
Important Safety Instructions - To ensure proper
installation and operation, take a moment to read
this guide before proceeding with the installation.
If you have any questions or comments about the
T.0X Series Optical Fiber Transmitters and Receivers
please contact your dealer.
WARNING: TO PREVENT FIRE OR ELECTRICAL SHOCK
DO NOT EXPOSE TO RAIN OR MOISTURE.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER.
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED
PERSONNEL.
A product and cart combination should be
moved with care. Quick stops, excessive force
and uneven surfaces may cause the product and
cart combination to overturn.
The lightning ash with arrow head symbol,
within an equilateral triangle, is intended to
alert the user to the presence of uninsulated
“dangerous voltage” within the product’s
enclosure that may be of sucient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to
the presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the product.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS PRODUCT
TO RAIN OR MOISTURE. DO NOT OPEN
THE CABINET, REFER SERVICING TO
QUALIFIED PERSONNEL ONLY.
CAUTION: TO PREVENT ELECTRIC SHOCK, DO NOT
USE THIS (POLARIZED) PLUG WITH AN
EXTENSION CORD RECEPTACLE OR OTHER
OUTLET UNLESS THE BLADES CAN BE FULLY
INSERTED TO PREVENT BLADE EXPOSURE.

connected to cables to prevent the laser beam from
damaging the eyes.
Do not turn the transmitter on without a ber optic
cable connected to it.
Warning.-
This product emits an invisible laser beam. Avoid
contact with laser radiation. The use of binoculars
or magnifying glasses may increase damage caused
to the eyes.
According to EN60825-1_ 2007
The use of the equipment in any other way than the
specied in this manual may lead to exposure to
harmful radiation.
Do not use the equipment in any way that does
not comply with the operating instructions or
in any conditions that exceed the stipulated
environmental specications.
Never point the laser beam at people or animals.
16. Replacement Parts - Ensure that repairs are
performed by qualied technicians and that only
manufacturer supplied or authorized parts are used.
17. Safety Check – Upon completion of any service
or repairs to this product, ensure safety checks
to determine that the product is functioning per
manufacturer specications are performed.
18. Heat - The product should be situated away from
heat sources such as radiators, heat registers, stoves,
or other products (including ampliers) that produce
heat. Ensure that ambient temperature is maintained
in the manufacturer specied operating range.
Optical connection instructions:
An SC/APC single mode ber cable must be used.
Remove the protective cover from the optical
connector on the unit and the cap on the cable
connector.
Carefully align the guides on both connectors
when plugging a cable to the device, then push the
connector all the way in.
Take special care to avoid damaging the unprotected
ends of the connectors, as small scratches,
impurities and/or particles of dirt, oil, grease, sweat,
etc. may signicantly aect the quality of the signal.
To clean the ends of the connectors, gently rub
with a lint-free lens cleaning cloth, dampened
using additive-free isopropyl alcohol. Make sure the
alcohol evaporates fully before connecting. Keep
the connector covers and cable caps in a safe place
in case they are needed in the future. Always t the
covers on the connectors of devices that are not
routed correctly to avoid damage including pinching,
excessive bends, or compression.
12. Electrical Supply, Grounding, and Surge
Protection – Ensure that all local or national electrical
codes are followed. Seek the advice of a licensed
electrician, profesional engineer, or other licensed
expert. See example wiring gure.
13. Power Lines - Always use caution and avoid
operating this or any connected equipment near
uninsulated power line or any other hazards.
14. Object and Liquid Entry - Never allow objects or
liquid of any kind into this product through openings.
Doing so could result in re or electric shock.
15. Servicing – There are no user serviceable parts. Do
not attempt to service this product or remove covers.
Doing so may expose you to dangerous voltage or
other hazards. Refer all servicing to qualied service
personnel. Examples of damage requiring service
include but are not limited to:
- Damage to power-supply wiring.
- If liquid has been spilled, or objects have fallen into
the product.
- If the product has been exposed to rain or water.
- If the product does not operate normally by
following the operating instructions. Adjust only
those controls that are covered by the operating
instructions as an improper adjustment of other
controls may result in damage and will often
require extensive work by a qualied technician to
restore the product to its normal operation.
- If the product has been dropped or physically
damaged.
- When the product exhibits a distinct change in
performance.
