WARNING: 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 table below are maintained.
Suitable user protection to ensure compliance with EN 60950
should be present on the card. A hazardous voltage is one which
exceeds 42.4 V peak ac or 60 V dc. If you have any doubt, seek
advice from a competent engineer before installing other
Dialogic
The equipment must be installed such that with the exception of the
connections to the host, clearance and creepage distances shown in the table
below are maintained between the Dialogic
assemblies which use or generate a voltage shown in the table below.

The larger distance shown in brackets applies where the local environment
within the host is subject to conductive pollution or dry non-conductive
pollution which could become conductive due to condensation. Failure to
maintain these minimum distances would invalidate the approval.
The clearance distance X is the shortest distance in air between two points.
The creepage path Y (along surfaces) is the shortest distance between the
same two points.
