• Use only the AC power adapter (if provided) and power cord included with the
equipment.
• Equipment should be installed near the power outlet and should be easily accessible.
• The shield of the coaxial cable must be connected to earth (grounded) at the
entrance to the building in accordance with applicable national electrical installation
codes. In the U.S., this is required by NFPA 70 (National Electrical Code) Article 820.
In the European Union and in certain other countries, CATV installation equipotential
bonding requirements are specified in IEC 60728-11, Cable networks for television
signals, sound signals and interactive services, Part 11: Safety. This equipment is
intended to be installed in accordance with the requirements of IEC 60728-11 for
safe operation.
• If the equipment is to be installed in an area serviced by an IT power line network, as
is found in many areas of Norway, special attention should be given that the
installation is in accordance with IEC 60728-11, in particular Annex B and Figure B.4.
• In areas of high surge events or poor grounding situations and areas prone to
lightning strikes, additional surge protection may be required (i.e. PF11VNT3 from
American Power Conversion) on the AC, RF, Ethernet and Phone lines.
• When the telephony modem is connected to a local computer through Ethernet
cables, the computer must be properly grounded to the building/residence AC
ground network. All plug-in cards within the computer must be properly installed
and grounded to the computer frame per the manufacturer’s specifications.
• Ensure proper ventilation. Position the telephony modem so that air flows freely
around it and the ventilation holes on the unit are not blocked.
• Do not mount the telephony modem on surfaces that are sensitive to heat and/or
which may be damaged by the heat generated by the telephony modem, its power
supply, or other accessories.
