6.1. Standard connections and timer setting

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

The centre earth terminal is intended as an optional connection to a local

earth for the purpose of enhanced protection from lightning transients, and is

not required in terms of user safety from the telephone network.

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) 73/23/EEC.

The timer is set by the position of a two-way jumper plug on a three-pin

header. Position the jumper to the left to set the timer ON, and to the right to

set it OFF. Leaving the jumper unconnected will default to the timer being

OFF.

This unit is supplied with the switch set to the OFF position.

Note – this optional connection is only available if specifically ordered.

Contact GAI-Tronics for details.

The additional hook contact is provided on TB1. The diagram shows the state

of the changeover contacts when the telephone is on hook. These contact

labels are also on the PCB.
