3 Approval
Information
This section provides information on the approval of the E1/T1 PCI card, and information that
may affect the approval status of the card in use. Failure to use the E1/T1 PCI card in accordance
with any of these instructions may invalidate the approval for connection.
3.1 Safety
Warnings
If you are unsure about installation and connection to the network, seek advice from a
competent telecommunication engineer before proceeding.
The network ports on the E1/T1 PCI cards are only suitable for connection to TNV (Telecom
Network Voltage) circuits operating as SELV (Safety Extra Low Voltage) TNV class 1.
The ports have the following safety status:
Type of Circuit
Port Description
SELV
Host Bus Interface (PCI)
SELV H.100
Telecommunications
Bus
SELV (TNV class1)
RJ45 Network Interface ports
CAUTION
When making a network connection, to reduce the risk of fire, only telecommunications line cord of 26 AWG or larger may be used.
See the appendices following this
General Approvals Information
for additional country specific safety
related information.
3.2 EMC
Compliance
The card has been tested for compliance with EMC regulations in the USA, Canada, the UK,
Europe and Australia in conjunction with a compliant system. This does not guarantee that every
EMC compliant system will remain compliant when used with the card. In extreme cases, high
frequency energy within the system may be conducted out of the system and re-radiated via the
network cables. In this case, the network cables may require additional treatment (such as
clamp-on ferrite rings), and system-grounding provisions may require modification.
Good quality shielded cables must be used for the network connections in all cases.
If there is doubt regarding the overall EMC performance of a particular system, the user is
advised to obtain competent advice, and local systems testing for EMC. Should local testing
identify that additional EMC protection is required in the form of E1/T1 trunk cable clamping,
you can refer to Appendix F: for guidance on the retrofit of Aculab Ferrite Clamps.
