Requirements for European Operation

114200-C Rev 00

D-11

The creepage distances apply to the normal office environment. When the local

environment within the host chassis is subject to conductive pollution or dry

nonconductive pollution that could become conductive due to condensation, the

creepage distances shown in parentheses in Table D-11

apply.

The clearance and creepage distance between adjacent points should be checked

as follows:

• The clearance distance (X) is the shortest distance between two points

measured through the air.

• The creepage distance (Y) is the shortest distance between two points

measured across a surface.

If in doubt about calculating these distances, obtain advice from a competent

telecommunications safety engineer. Failure to install the ISDN BRI or serial

adapter module according to these instructions invalidates the conditions of the

BABT General Approval agreement.
