CDM-500 Satellite Modem Preface
Rev. 1.3 ix
Installation
The installation and connection to the line supply must be made in compliance to local or
national wiring codes and regulations.
The CDM-500 is designed for connection to a power system that has separate earth, line
and neutral conductors. The equipment is not designed for connection to power system
which has no direct connection to earth.
The CDM-500 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.
Telecommunications Terminal Equipment Directive
In accordance with the Telecommunications Terminal Equipment Directive 91/263/EEC,
this equipment should not be directly connected to the Public Telecommunications
Network.
EMC (Electromagnetic Compatibility)
The CDM-500 VSAT Modem has been demonstrated, 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.
FCC Part 15 Class B
Immunity: EN 50082 Part 1 - Generic immunity standard, Part 1: Domestic,
commercial and light industrial environment.
In order that the Modem continues to comply with these standards, observe the following
instructions:
•
Connections to the transmit and receive IF ports (BNC female connectors) should be
made using a good quality coaxial cable – for example RG58/U (50 ohm) or RG59/U
(75 ohm).
•
All 'D' type connectors attached to the rear panel must have back-shells which 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.
