POWER CONNECTION
It is recommended to route in separately cable racks, trays or ducts, the following cable types:
▪
Single-wire signal or data cables with V< 60V
▪
Single wire cable with 60V<V< 230V
▪
Input power cables with low level of interferences 230V<V<1000V
▪
Output motor power cables and DC cables with high level of interferences 230V<V<1000V.
▪
Medium voltage cables with V<1000V
The power cables must have sufficient current rating to prevent important wiring overheating and voltage
drops. The installer must consider the cable cross-section, cable type, routing method and the ambient
conditions to select the appropriate cable. It is only permitted the use of cooper or aluminium cables. The
maximum cable section and the available holes per phase could be found in the “Power connection
terminals” section.

The DC conductors will depend on the photovoltaic installation design. The installation must be
consistent with current country regulations.
