Determine the clearance and creepage distance between adjacent points as
follows:
• The clearance distance (X) is the shortest distance between two points
through the air.
• The creepage distance (Y) is the shortest distance between two points
measured across a surface.
If you have any questions, consult a competent telecommunications safety
engineer. Failure to install the ISDN BRI according to these instructions will
invalidate the General Approval.
