The control panel enclosure must not be opened before isolating the mains supply.

The cover must be securely fitted in normal use.

Mains Cable Type

The conductors of the mains supply cable must have a minimum cross-sectional area

of 0.75 mm and the insulating material on each conductor must be a minimum of 0.4

mm thick Polyvinyl Chloride (pvc). Flexible cables must conform to the requirements

of BS6500 and IEC Publication 227. Non-flexible electrical installation cables must

conform to BS6004.

Telecoms Approvals

Connection to the PSTN

The Telecommunications Network Voltage (TNV) port (terminals A and B on TB5)

must be permanently connected (hard-wired) to the PSTN via a BT master socket. If

the BT master socket is a newer type (NTE5/CTE5), the connection can be carried out by

the installation engineer. If the BT master socket is not an NTE5/CTE5, then the connec-

tion must be made by the network operator. The Accord control panel should be

connected to the BT master socket using cable suitable for connection to 2.8 mm

diameter screw terminals.

Note: Prevent exposure to potentially lethal voltages from the PSTN by replacing the

Control Panel cover when connection to the BT master socket is complete.

Interconnecting circuit equipment should comply with the requirements of 4.2 of

EN41003 for TNV (Telephone Network Voltage) circuits and 2.3 of EN60950 of

SELV (Safety Extra Low Voltage) circuits. Compliance must continue after making

connections between circuits.

Approvals

The Accord xpC is approved for connection to direct lines of the PSTN and PBX

exchanges (with or without secondary proceed indication).

It should be noted that the Accord xpC is not suitable as an extension to a payphone.

The Accord xpC has been approved for the use of the following facilities:

• Auto-dialling.

• Auto-answering.

• Auto-clearing.

• Modem communications.

• Series connection.

• Operation with Call Process Monitor (CPM) tone recognition.

• Multiple repeat attempts.

Any other usage invalidates the approval of the Accord xpC if, as a result, it then

ceases to comply with standards against which approval was granted.
