Preface
Translated Safety Warnings
Distance Limitations for Signaling and Unshielded Conductors
Give special consideration to the effect of a lightning strike in the site vicinity if wires exceed
recommended distances, or if wires pass between buildings. The electromagnetic pulse (EMP) caused
by lightning or other high-energy phenomena can easily couple enough energy into unshielded
conductors to destroy electronic devices.
Provide a properly grounded and shielded environment. Consider electrical surge suppression issues by
addressing the following items:
• Potential surge sources
• Distance
Caution Splicing can degrade cable performance.
Translated Safety Warnings
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may
harm you. A warning symbol precedes each warning statement. The following paragraph is an example
of a safety warning. It identifies the warning symbol and associates it with a bodily injury hazard. The
remaining paragraphs in this section are translations of the initial safety warning.
Note For a complete list of translated safety warnings, read the Regulatory Compliance and Safety
Information for the Cisco 10720 Internet Router publication that accompanies your
Cisco 10720 Internet Router. We recommend you read and understand the safety warnings and
guidelines before installing, configuring, or maintaining the router.
Warning
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you
work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar
with standard practices for preventing accidents. (To see translations of the warnings that appear in
this publication, refer to the appendix “Translated Safety Warnings” in the installation guide that
accompanied this device.)
Waarschuwing
Dit waarschuwingssymbool betekent gevaar. U verkeert in een situatie die lichamelijk letsel kan
veroorzaken. Voordat u aan enige apparatuur gaat werken, dient u zich bewust te zijn van de bij
elektrische schakelingen betrokken risico’s en dient u op de hoogte te zijn van standaard
maatregelen om ongelukken te voorkomen. (Voor vertalingen van de waarschuwingen die in deze
publicatie verschijnen, kunt u het aanhangsel “Translated Safety Warnings” (Vertalingen van
veiligheidsvoorschriften) in de installatiegids die bij dit toestel is ingesloten, raadplegen.
Varoitus
Tämä varoitusmerkki merkitsee vaaraa. Olet tilanteessa, joka voi johtaa ruumiinvammaan. Ennen
kuin työskentelet minkään laitteiston parissa, ota selvää sähkökytkentöihin liittyvistä vaaroista ja
tavanomaisista onnettomuuksien ehkäisykeinoista. (Tässä julkaisussa esiintyvien varoitusten
käännökset löydät tämän laitteen mukana olevan asennusoppaan liitteestä "Translated Safety
Warnings" (käännetyt turvallisuutta koskevat varoitukset).)
