APPENDIX D

SAFETY WARNINGS AND REQUIREMENTS

These warning notices apply to the Input Port, the port marked

“Network”.

Warning: The port marked “SAFETY WARNING: see instructions

for use” does not provide isolation sufficient to satisfy the requirements
of BS6301; apparatus connected directly to this port should either have
been approved to BS6301 or have previously been evaluated against
British Telecommunications plc (Post Office) Technical Guides 2 or 26
and given permission to attach.  Any other usage will invalidate the
approval of the Interface Module.  

Interconnection of the Interface Module (the port marked

“Network”) directly, or by way of any other apparatus, with ports on
other apparatus (marked or not so marked) may produce hazardous
conditions on the network.  Users should seek advice from a compe-
tent engineer before such a connection is made.

The Interface Module is approved as a Host Independant

Appliqué.  As such the Interface Module is only approved for use with
a host, and with host attachments, that are either type approved in
their own right, or, if supplied after March, 1989, are covered by terms
of the General Approval number NS/G/1234/J/100003.  A Host sup-
plied under the terms of the General Approval number
NS/G/1234/J/100003 satisfies the conditions of the paragraph above.

The Interface Module must not be modified in any way.  Any form

of modification invalidates the approval for connection, and the Patton
warranty of the unit.

The terms of the approval require that there must be a minimum

distance (5mm) between the Interface Module and any other part of
the host, including other Interface Modules.  This condition is met by
default when the Appliquè is installed in a Patton enclosure in accor-
dance with the instructions.  If voltages greater than 250V are present
in the host , users should refer to a competent safety engineer for
advice.

It is a condition of the approval that a copy of these user instruc-

tions and safety warnings must be supplied with the host.  Failure to
provide the Interface Module user instructions with the host will invali-
date the Appliquè approval.

Failure to install the Interface Module in accordance with these

instructions will invalidate the approval.  If you experience difficulties,
or are in any doubt, please contact your Patton representative.
