ESD Warning
1
Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
ESD Warning
To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are
properly grounded before touching any internal materials.
When working with any equipment manufactured with electronic devices, proper ESD
grounding procedures must be followed to make sure people, products, and tools are as free of
static charges as possible. Grounding straps, conductive smocks, and conductive work mats
are specifically designed for this purpose.
Anyone performing field maintenance on AMX DXLink equipment should use an appropriate
ESD field service kit complete with at least a dissipative work mat with a ground cord and a UL
listed adjustable wrist strap with another ground cord. These items should not be manufactured
locally, since they are generally composed of highly resistive conductive materials to safely
drain static charges, without increasing an electrocution risk in the event of an accident. ESD
protective equipment can be obtained from 3M™, Desco®, Richmond Technology®, Plastic
Systems®, and other such vendors.

Important Safety Information and Instructions
2Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Important Safety Information and Instructions
When using and installing your AMX product, adhere to the following basic safety precautions.
For more information about operating, installing, or servicing your AMX product, see your
product documentation.
Read and understand all instructions before using and installing AMX products.
Use the correct voltage range for your AMX product.
There are no user serviceable parts inside an AMX product; service should only be
done by qualified personnel.
If you see smoke or smell a strange odor coming from your AMX product, turn it off
immediately and call technical support.
For products with multiple power supplies in each unit, make sure all power supplies
are turned on simultaneously.
Use surge protectors and/or AC line conditioners when powering AMX products.
Only use a fuse(s) with the correct fuse rating in your enclosure.
Make sure the power outlet is close to the product and easily accessible.
Make sure the product is on or attached to a stable surface.
Turn off equipment before linking pieces together, unless otherwise specified in that
product’s documentation.
For safety and signal integrity, use a grounded external power source and a grounded
power connector.
To avoid shock or potential ESD (Electrostatic Discharge) damage to equipment,
make sure you are properly grounded before touching components inside an AMX
product.

d’indication contraire fournie dans la documentation de l’appareil.
Par mesure de sécurité et pour la qualité des signaux, servez-vous d’une source
d’alimentation externe mise à la terre et d’un connect d’alimentation mis à la terre.
Pour éviter les chocs ou les dommages éventuels causés à l’équipement par une
décharge électrostatique, veillez à ce le dispositif oit bien relié à la terre avant de
toucher les composantes se trouvant à l’intérieur d’un appareil AMX.
