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.
6.2. Additional hook contact
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.
