Required Cable Length - Delta EV Ultra Installation Manual

Example of calculation for charger with 150kW DC charge capacity, 22kW AC and 43kW AC charge capacity:
Note! Charger controller will limit I
The recommended minimal cable cross section accepted by charger terminals is 95mm
cross section accepted by terminals is 300mm
bending radius is suitable for cable glands and plinth dimensions.
Use of aluminium cable is prohibited. The charger is cyclic load resulting to cycling thermal expansion and
contraction of cables. This increase risk of hotspots. During annual maintenance, check the cable connection
in charger and also in distribution board.

Note! Cable cross section is based on IEC 60364-5-52:2011 standard (Cu conductor, multi-core
cable, 3 live cores, PVC insulation, in the earth – D2 case). Site specific conditions must be taken
into account for proper dimensioning. For different types of cables and installation conditions please
refer to cable fact sheet or consult with Delta customer service.

4.1.2 Required cable length

Installation site should be prepared with AC cabling to supply L1, L2, L3, N, PE. Cable length should be at
least 1,5 meter long from base. Cable should be prepared inside the footprint of the EV quick Charger. Check
exact cable location in chapter 4.5.3
