International Regulatory Information

ENGLISH

Installation within a spare slot position

The equipment must be installed such that with the exception of the connections to

the host, clearance and creepage distances shown in the table below are

maintained between the adapter and any other assemblies which use or generate

a voltage shown in the table below.

The larger distance shown in brackets applies where the local environment within

the host is subject to conductive pollution or dry non-conductive pollution which

could become conductive due to condensation. Failure to maintain these minimum

distances would invalidate the approval.

The clearance distance X is the shortest distance in air between two points. The

creepage path Y (along surfaces) is the shortest distance between the same two

points.

WARNING: It is essential that, when other option cards are introduced which use

or generate a hazardous voltage, the minimum creepages and

clearances specified in the table below are maintained. Suitable

user protection to ensure compliance with EN 60950 should be

present on the card. A hazardous voltage is one which exceeds

42.4 V peak a.c or 60 V d.c. If you have any doubt, seek advice from

a competent engineer before installing other adapters into the host

equipment.
