Recommended Standard Designations
Electronic Industries Association (EIA) designations supersede Recommended
Standard (RS) designations. Reference to the old RS designations may appear
when depicting actual text (e.g., RS-232) as it may appear on the product rear
panels or on screens or pages in the Serial Remote or HTTP (Web Server)
Interfaces. All other references in the manual specify the EIA designations.
CAUTION
YOU SHOULD CAREFULLY REVIEW THE FOLLOWING INFORMATION.
Safety and Compliance
Electrical Safety and Compliance
The unit complies with the EN 60950 Safety of Information Technology
Equipment (Including Electrical Business Machines) safety standard.
The unit is rated for operation over the range 100 to 240 VAC. It has a maximum
power consumption of 88 watts, and draws a maximum of 770 mA.
Class I Pluggable Equipment Type A-Protective Earthing
The cable distribution system/telecommunication network of this product relies
on protective earthing. The integrity of the protective earthing must be ensured.
In Finland:
"Laite on liitettävä suojakoskettimilla varustettuun pistorasiaan."
In Norway:
“Apparatet må tilkoples jordet stikkontakt.”
In Sweden:
“Apparaten skall anslutas till jordat uttag.”
In Denmark:
"Apparatets stikprop skal tilsluttes en stikkontakt med jord, som giver
forbindelse til stikproppens jord."

Galvanic Isolator Use
In Norway:
“Utrustning som är kopplad till skyddsjord via jordat vägguttag och/eller via
annan utrustning och samtidigt är kopplad till kabel-TV nät kan i visa fall medfőra
risk főr brand. Főr att undvika detta skall vid anslutning av utrustningen till kabel-
TV nät galvanisk isolator finnas mellan utrustningen och kabel-TV nätet.”
Restricted Access Location
In Nordic Countries, equipotential bonding should be applied using the
permanently connected ground stud by a qualified service person.
Battery Warning
CAUTION
There is risk of explosion if you replace your battery with an incorrect
type. Dispose of used batteries according to the instructions.
Electrical Installation
CAUTION
Connect the ground stud, located on the modem rear panel, to a
power system that has separate ground, line, and neutral conductors.
Do not connect the unit without a direct connection to ground.
Chapter 4.2.3. Unit Ground Connection
Fusing
CAUTION
For continued operator safety, always replace the fuses with the
correct type and rating.

The unit is fitted with two fuses – one each for line and neutral connections.
They are contained inside a press-fit fuse holder that is part of the IEC power
module:
•Use T2.00A 20mm fuses for 115 and 230 volt AC operation.
•Use T6.25A 6.3 x 32mm fuses for 48 volt DC operation.
Operating Environment
CAUTION
Do not operate the unit in any of these extreme operating conditions:
•Ambient temperatures less than 0° C (32° F) or more than 50° C
(122° F).
•Precipitation, condensation, or humid atmospheres of more than
95% relative humidity.
•Unpressurized altitudes of more than 2000 metres (6561.7 feet).
•Excessive dust.
•Flammable gases.
•Corrosive or explosive atmospheres.

Independent testing verifies that the unit complies with the European Union
R&TTE Directive, its reference to EN 301 489-1 (Electromagnetic compatibility
and Radio spectrum Matters [ERM]; ElectroMagnetic Compatibility [EMC]
standard for radio equipment and services, Part 1: Common technical
requirements), and the Declarations of Conformity for the applicable directives,
standards, and practices that follow:
