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 T

able B-2 will apply.

The clearance and creepage distance between adjacent points should be checked

as follows (Figure

B-1):

• 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.
