Important Safety Considerations When Installing Into A Host
Computer System
The Eiconcard C2x is a single PCI card.
Installation Within A Spare Slot Position
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 EN60950/A4 should be
present on the card. A hazardous voltage is one which exceeds 42.4V
peak a.c or 60V d.c. If you have any doubt, seek advice from a
competent engineer before installing other adapters into the host
equipment.
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 card and any other assemblies which use
or generate a voltage shown in the table below.
Table 4. Creepage Distances
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.
