Regulatory Information
Installation of the Communications Board
Electrical Power
Before making connections, check the safety levels on the various interfaces:
•
Telephone line connector = TNV
•
ISA connector = SELV
These indications are classified as per security standard EN 60-950/A2 10/93
•
SELV: Very Low Safety Voltage
•
TNV: Telecommunications Network Voltage, voltages in compliance with standard EN 60950 criteria.
The HP PC communications board is approved only for installation in a 'host' computer (PC) and with host attachment, which are either type
approved for such apparatus, or covered by a General Approval.
It is a condition of type approval that the power required by the host and the total of all other adapter cards installed within the host apparatus,
together with any auxiliary apparatus, does not exceed the power specification as stated in the Online Reference Guide.
The equipment is to 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 board and any other assemblies which use or generate a voltage. The larger distance shown in brackets
applies where the local environment within the host is subject to conductive pollution or non-dry conductive pollution which could become
conductive due to condensation.
Failure to maintain these minimum distances would invalidate the approval.
In case of doubt, please obtain advice from a competent telecommunications safety engineer.

For a host or other expansion board fitted in the host, using or generating voltages greater than 300 Vrms or Vdc, advice from a competent
telecommunication safety engineer must be obtained before installation of the relevant equipment.
It is a condition of approval that the power required by the host and the total of all adapter boards installed within the host environment,
together with any auxiliary apparatus, does not exceed the power specification as stated in the Online Reference Guide.
Ensure that only equipment having connection points with the same safety status as identified above is connected to each individual
interconnection point provided by the HP PC communications board.
Always disconnect the host PC from the power supply before removing the cover.
Always disconnect the host PC from any analog telephone circuits before removing any covers.
Failure to install the HP PC communications board in accordance with the instructions provided above will invalidate the approval.
If you have any doubt as to how to safely install the HP PC communications board correctly within a host chassis, please seek advice from a
qualified telecommunications engineer.
