Safety Requirements

ARRIS Telephony Modems comply with the applicable requirements for

performance, construction, labeling, and information when used as

outlined below:

• The Telephony Modem is designed to be connected directly to a

telephone.

• Connecting the Telephony Modem to the home's existing tele-

phone wiring should only be performed by a professional in-

staller.

• Do not use product near water (i.e. wet basement, bathtub,

sink or near a swimming pool, etc.), to avoid risk of electrocu-

tion.

• Avoid using and/or connecting the equipment during an electri-

cal storm, to avoid risk of electrocution.

• Use only power supply and power cord included with the equip-

ment.

• 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 instal-

lation 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 in-

tended 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, spe-

cial attention should be given that the installation is in accor-

dance 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 Conver-

sion) on the AC, RF, Ethernet and Phone lines.

• When the Telephony Modem is connected to a local computer

through USB or Ethernet cables, the computer must be proper-

ly 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.

CAUTION

Potential equipment damage

Potential loss of service

Connecting the Telephony Modem to existing

telephone wiring should only be performed by a

professional installer. Physical connections to the

previous telephone provider must be removed and

the wiring must be checked; there must not be any

voltages. Cancellation of telephone service is not

adequate. Failure to do so may result in loss of

service and/or permanent damage to the Telephony

Modem.

CAUTION

Potential equipment damage

Do not locate the equipment within 6 feet (1.9m) of

a flame or ignition source (e.g. heat registers, space

heaters, fireplaces, etc.), to avoid damage or injury

from battery explosion.
