Preface

Electrical Safety

The CDM-700 Modem has been shown to comply with the EN 60950 Safety of Information
Technology Equipment, including electrical business machines safety standard.
The equipment is rated for operation over the range 100 - 240 volts AC. It has a maximum power
consumption of 75 watts, and draws a maximum of 0.75 mA.
The user should observe the following instructions:
IMPORTANT

Fuses

The CDM-700 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 CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES
WITH THE CORRECT TYPE AND RATING.
CAUTION

Environmental

The CDM-700 must 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.

direct connection to ground.
The CDM-700 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
