If fitting 2 wires to one terminal the sum of the 2 wires must be a maximum cross sectional area of 2.5mm². Wires may also be fitted
using ferrules. When connecting wires to the terminals 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.
AC Wiring
Terminal blocks are provided on the AC horns for power connection. There are (2) Line, (2) Neutral and (2) Earth Ground terminals
in total. A 3-position terminal is provided for stage switching with a stage 2, a stage 3 and a common terminal.
