E2S E2 C1LD2F Series Instruction Manual page 4

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.
8) Wiring the Combined Beacon & Sounder
for Simultaneous or Independent
Operation.
By default, the Beacon and Sounder PCBAs are pre-wired
together for simultaneous operation. The units will be
powered simultaneously if either the sounder or beacon
board is powered. Stage switching is only available on the
sounder boards. If the sounder and beacon boards are
required to operate independently, the wires connecting the
Beacon and Sounder PCBAs should be removed from both
sets of terminal blocks, refer to fig. 3b & 5b.
9) AC Wiring
A 6-way terminal block is provided on the AC Sounder for
power. There are 2-off Live, 2-off Neutral and 2-off Earth
terminals in total. A 3-way terminal is provided for stage
switching. There are 1-off stage 2, 1-off stage 3 and 1-off
common terminals in total. 3-off 2-way terminal blocks are
provided on the AC beacon for power. There are 2-off +ve, 2-
off -ve and 2-off Earth terminals in total.
