The equipment is rated for operation over the range 100 to 240 VAC. It has a maximum power
consumption of 60 watts, and draws a maximum of 600 mA.
IMPORTANT
The user should observe the following instructions:
Fuses
The CDM-710 is fitted with two fuses - one each for line and neutral connections. These are
contained within the body of the IEC power inlet connector, behind a small plastic flap.
For 115 and 230 volt AC operation, use T2.00A, 20mm fuses.
For 48 VDC operation, use T6.25A, 6.3x32mm fuses.
CAUTION
FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES WITH
THE CORRECT TYPE AND RATING.

Environmental
The CDM-710 shall not be operated in an environment where the unit is exposed to extremes of
temperature outside the ambient range 0 to 50°C (32° to 122°F), precipitation, condensation, or
humid atmospheres above 95% RH, altitudes (un-pressurized) greater than 2000 meters,
excessive dust or vibration, flammable gases, corrosive or explosive atmospheres.
Operation in vehicles or other transportable installations that are equipped to provide a stable
environment is permitted. If such vehicles do not provide a stable environment, safety of the
equipment to EN60950 may not be guaranteed.
Installation
The installation and connection to the line supply must be made in compliance to local or national
wiring codes and regulations.
The CDM-710 is designed for connection to a power system that has separate ground, line and
neutral conductors. The equipment is not designed for connection to power system that has no
direct connection to ground.
The CDM-710 is shipped with a line inlet cable suitable for use in the country of operation. If it is
necessary to replace this cable, ensure the replacement has an equivalent specification. Examples
of acceptable ratings for the cable include HAR, BASEC and HOXXX-X. Examples of
acceptable connector ratings include VDE, NF-USE, UL, CSA, OVE, CEBEC, NEMKO,
DEMKO, BS1636A, BSI, SETI, IMQ, KEMA-KEUR and SEV.

RoHS Compliancy
This unit satisfies (with exemptions) the requirements specified in the European Union Directive on
the Restriction of Hazardous Substances, Directive 2002/95/EC, (EU RoHS).
EMC (Electromagnetic Compatibility)
In accordance with European Directive 89/336/EEC, the CDM-570/570L Modem has been
shown, by independent testing, to comply with the following standards:
Emissions: EN 55022 Class B - Limits and methods of measurement of radio
interference characteristics of Information Technology Equipment.
(Also tested to FCC Part 15 Class B)
Immunity: EN 50082 Part 1 - Generic immunity standard, Part 1: Domestic,
commercial and light industrial environment.
Additionally, the CDM-570/570L has been shown to comply with the following
standards:
EN 61000-3-2 Harmonic Currents Emission
EN 61000-3-3 Voltage Fluctuations and Flicker
EN 61000-4-2 ESD Immunity
EN 61000-4-4 EFT Burst Immunity
EN 61000-4-5 Surge Immunity
EN 61000-4-6 RF Conducted Immunity
EN 61000-4-8 Power frequency Magnetic Field Immunity
EN 61000-4-9 Pulse Magnetic Field Immunity
EN 61000-4-11 Voltage Dips, Interruptions, and Variations Immunity
EN 61000-4-13 Immunity to Harmonics
IMPORTANT
To ensure that the Modem continues to comply with these
standards, observe the following instructions:
Connections to the transmit and receive IF ports („N‟ type female connectors) should be made
using a good quality coaxial cable - for example, RG213/U.
All 'D' type connectors attached to the rear panel must have back-shells that provide
continuous metallic shielding. Cable with a continuous outer shield (either foil or braid, or
both) must be used, and the shield must be bonded to the back-shell.
The equipment must be operated with its cover on at all times. If it becomes necessary to
remove the cover, the user should ensure that the cover is correctly re-fitted before normal
operation commences.
