Service Requirements

In case of equipment malfunction, all repairs should be carried out by Aculab plc. It is the

responsibility of users requiring service to report the need for service to our company.

Service can be obtained at :

EN55022 declaration

This is a class B product. In a domestic environment, this product may cause radio interference

in which case the user may be required to take adequate measures.

No changes or modification to the MC3 PCI card is allowed without explicit written permission

from Aculab, as these could void the end user's authority to operate the device.

Safety Warnings

Interconnection circuits should be such that the equipment continues to comply with the

requirements of 2.3 of EN 60950 for SELV circuits, after making connections between circuits

using any of the internal ports.

Installation and Safety

The following information regarding installation is provided for guidance only and does not

eliminate the need for competence on the part of the installer.

The card must be installed such that with the exception of the PCI bus and H.100 connections,

clearance and creepage distances shown in the table below are maintained between the MC3

PCI card and any parts of the host PC or other expansion cards which use or generate a voltage

shown in the following table.

Clearance mm

2.0

2.6

4.0

For a host or other expansion card fitted in the host,

using or generating voltages greater than 300V (rms

or dc), advice from a competent

telecommunications safety engineer must be

obtained before installation of the relevant

equipment.

Clearance distances refer to the shortest distance between parts, measured through air. Creepage

distances refer to total distances measured across surfaces when installed in a normal office

environment. The creepage distances in parenthesis apply where the local environment within

the PC is subject to conductive pollution or dry non-conductive pollution that could become

conductive due to condensation.
