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.

You should obtain advice from a competent telecommunications safety engineer if
in doubt. Failure to install the ISDN BRI or serial adapter module according to
these instructions invalidates the General Approval.
