CABLES AND WIRING
The wiring requires to SEPARATE the power cable 12Vdc (ex. 2x0.5 + Nx0.22),to the power cable for heaters
24Vac (ex. 2x0.75) to prevent input of disorders of the AC voltage on the barrier.
Note: is absolutely necessary to shield the cable that provides 12 Vdc power supply and
put the metal braid to ground.
The cable dimension depends on the columns consumption and on the same cable resistance, taking care about
installation distances.
Cable 230Vac (culomn power)
Cable 12Vcc (sync + signal)
