Preface MN/CRS100.IOM
vii
Operation in vehicles or other transportable installations which 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
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 CRS-100 1:1 Redundancy Switch 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 CRS-100 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
Ω
) or
RG59/U (75
Ω
).
•
All 'D' type connectors attached to the unit 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.
