The above creepage distances apply in a normal office environment. In the
presence of conductive pollution, or voltages greater than 300 V (rms or dc),
or if you have any doubt, seek advice from a competent telecommunication
safety engineer before the installation.
Creepage and clearance distances can be checked by measuring between the
adjacent parts as shown below. Clearance distance X is the shortest distance
in air between two parts. Y is the length of the creepage path between the
same two parts.

4.4 Product Environmental Information
During August 2005, the European Union Directive on Waste Electrical and
Electronic Equipment (2002/96/EC) and its amendment (2003/108/EC),
collectively known as the WEEE Directive, came into force throughout most of
the European Union. These Dialogic
® products come within the scope of the
WEEE Directive. We are confident that this product will provide you with
many years of reliable service. Moreover, we are pleased to advise you that
Dialogic warrants this product, as detailed in the user guide and provides a
fee based repair service when the product is out of warranty. However, a
time will come when the product will no longer meet your needs or will
become un-economic to repair. It is at that stage that we ask for your co-
operation in recycling this product in the spirit of the WEEE directive.
