way, the sum of the 2-off wires must be a maximum cross
sectional area of 2.5mm². Strip wires to 8mm. Wires may also
be fitted using ferrules. Terminal screws need to be tightened
down with a tightening torque of 0.45 Nm / 5 Lb-in. When
connecting wires to the terminals great care should be taken
to dress the wires so that when the cover is inserted into the
chamber the wires do not exert excess pressure on the
terminal blocks. This is particularly important when using
cables with large cross sectional areas such as 2.5mm².
12) AC Wiring
Four connections must be made to the BExCTS110-05D AC
unit. A power supply input cable should enter the enclosure
via one of the M20 entries and a telephone signal cable
should enter through the other M20 entry.
Connect the power input (L) to the telephone board (L/+)
terminal in the sounder section & power input (N) to the
beacon board (N) terminal in the beacon section.
Connect the telephone signal input to (TB1) on the telephone
board in the sounder section. See Figure 4

13) DC Wiring
Four connections must be made to the BExCTS110-05D DC
unit. A power supply input cable should enter the enclosure
via one of the M20 entries and a telephone signal cable
should enter through the other M20 entry.
Connect the power input (+) to the telephone board (L/+)
terminal in the sounder section & power input (-) to the
beacon board (-) terminal in the beacon section.
Connect the telephone signal input to (TB1) on the telephone
board in the sounder section. See Figure 5
