9.1 Type of cable
Wiring requires you to
SEPARATE
the SHIELDED cable
of
the 12Vdc power supply plus all the signals to
the control unit (e.g.2x0.5 + Nx0.22), from the power cable of the 24Vac heaters (optional for AQ
160m version) (e.g.2x0.75) to prevent the input of alternating voltage disturbances on the barrier.
N.B. it is absolutely necessary to shield the cable that supplies the 12 Vdc power supply and to
ground the metal braid.
The sizing of the cables depends on the consumption of the columns and on the resistance of the
cable itself according to the distances involved.
The table shows the cable cross-sections and the relative distances to ensure optimum performance
using the LAR22 power supply (12Vdc-2.5A/24Vac-300W) and an ALES QUAD barrier (1 pair)
The LAR22 can power up to 8 ALES QUAD barriers.The LAR22 container is metallic, so it must be placed
inside a room or put in a watertight container if used outdoors.A battery up to 18Ah can be housed in
the container.
