Use local regulations and datasheet of the manufacturer to determine the cable diameter for
the DC power cables. Recommended cable for the 450 kW system is 185 mm
2
(= 350 MCM)
(with a reinforced isolation > 5400 V DC) for a distance until 492.13 ft.
4.4.5. Cables between the Power Cabinets
The following cables are not in the scope of supply of ABB.
1x GND cable;
1x Interlock cable;
1x CAN cable.
NOTICE
For detailed information about type of glass fiber cable which are needed,
see
