Using cable suitable for connection to 2.8 mm diameter screw terminals, strip
back approximately 20 mm of the outer sheath and then remove approximately 4
mm of the insulation from the wires to be connected to the Galaxy 16 plus.
Connect the A wire to contact 2 on the BT master socket and the B wire to
contact 5. Connect the A and B wires to the A and B terminals of JP3 on the
Galaxy 16 plus, see Table 1.3 PSTN Connections to the Galaxy 16 plus.
Note: The cover of the control box must be replaced whenever any
connection to the BT master socket is completed to prevent exposure to
potentially lethal voltages from the PSTN.
Interconnection circuits should be such that the equipment continues to
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,
after making connections between circuits.
Connecting Additional Telecom Apparatus
A BT secondary socket, allowing additional telecom apparatus to be connected
in series with the Galaxy 16 plus can be connected to the TNV port C and D
(JP3) on the Galaxy 16 plus see Figure 1.14 Connecting the Galaxy 16 plus to the
PSTN.
Connect the contacts on the BT secondary socket to the JP3 as follows:
