conductive pollution which could become conductive due to condensation.  Failure to maintain these minimum distances would invalidate
the approval.

4)  The analogue telecommunications interface is intended to be connected to telecommunication network voltage (TNV) circuits which
may carry dangerous voltages. The telephone cord(s) must be disconnected from the telecommunications system until the card has been
installed within a host which provides the necessary protection of the operator.  If it is subsequently desired to open the host equipment for
any  reason,  the  telephone  cord(s)  must  be  disconnected  prior  to  effecting  access  to  any  internal  parts  which  may  carry
telecommunication network voltages.
