Appendix D - Regulatory Information
Compliance with BABT Requirements
Approved for connection to telecommunications system specified in
the instructions for use subject to the conditions set out in them.
Warning: Interconnection directly, or by way of other apparatus, of
ports marked "SAFETY WARNING see instructions for use" with
ports marked or not so marked may produce hazardous conditions
on the network. Advice should be obtained from a competent
engineer before such a connection is made.
It is a condition of approval that the power required by the host and
the total of all adapter cards installed within the host environment,
together with any auxiliary apparatus, does not exceed the power
specification as stated in the Technical Reference Material of the
host apparatus.
The power requirements for the MULTIMODEMISI are:
Modem operating voltages:
+12V D.C., -12V D. C., +5V D.C.
Modem Power Consumption: 8 Watts
In order to maintain the independent approval of this card, it is
essential that when other option cards are introduced which use or
generate a hazardous voltage, the minimum creepages and
clearances specified in the following table are maintained. A
hazardous voltage is one which exceeds 42.4V peak a.c or 50V d.c.
If you have any doubt, seek advice from a competent engineer
before installing other adapters into the host equipment.
The equipment must be installed such that with the exception of
connection to the host, clearance and creepage distances shown in
the following table are maintained between the card and any other
assemblies which use or generate a voltage shown in that table.
The larger the distance shown in brackets applies where the local
environment within the host is subject to conductive pollution or dry
nonconductive pollution which could become conductive due to
condensation. Failure to maintain these minimum distances would
invalidate approval.
