Power supply cables section
Signals / data lines
Do not overpass the maximum power allowed, which varies, according to the type of signal.
Lay the cables far from power cables or cables having a different tension and that are able to emit
electromagnetic disturbances.
Do not lay the cable near devices which can generate electromagnetic interferences.
Do not lay the cables parallel to other cables; cable crossings are possible, only if laid at 90°.
In case of parallel power supply and signal cables, use separate metal ducts. Minimum distance between
power supply and signal cables:
 300 mm for absorption up to 10A.

500 mm for absorption up to 50A.
Connect the screen to the ground, only if there aren’t disturbances.
Guarantee the continuity of the screen during the entire extension of the cable.
Respect impendency, capacity and attenuation indications.

EMC filter
Option available for installation in residential, commercial and light industrial environments for
conducted emissions (direct connection to the public grid).
It allows the unit to be installed in residential, commercial or light industrial environments, reducing electromagnetic
interference.
