IMPORTANT: If only one cable entry is used, the black blanking plug fitted to the

second position must be left in place.

Connect the telephone line A and B to the main terminal block TB2 as shown.

The centre earth terminal is intended for connection to a local earth to provide

common mode protection from lightning transients. If this terminal is not

earthed there is an increased risk that the telephone could be damaged

by line-born transients.

Note that user safety from the telephone network is provided by isolation and

does not rely on this earth connection.

Do not fit a terminating resistor across the telephone terminals. The

system does not require a terminating resistor, fitting a resistor may

prevent the telephone from initiating a call.

Note: Conductor sizes to be 0.5mm-2.5mm

(solid cable) The terminal block can be disconnected from the circuit board

for easier installation

Cabling must not infringe European Low Voltage Directive (LVD)

2006/95/EC.

(flexible cable);0.5-4.0mm
