ELECTRICAL INSTALLATION ECC 320
Multi-stranded or ne-stranded cables must be used for the AC main sup-
ply line (400 V). Furthermore, the L1/L2/L3, PE and N conductors must be
designed individually. Multi-conductor power cables cannot be routed into
the housing of the ECC 320.
When using aluminum cable, special cable lugs must be used.
EnerCharge recommends the use of copper conductors.

G INFORMATION
For the dimensioning of the AC supply line, please observe the following formula:
> Current AC (A) - Specications apply per phase:
61 A x (number of power modules) = XX Ampere.
Ex.: 61 x 8 (no. of modules at 40 kW each, 8 = 320kW) = 486 Ampere
> Active Power: 43 kW x (no. of modules) = XX kW.
Ex.: 43 x 8 (no. of modules at 40 kW each, 8 = 320 kW) = 344 kW
> Apparent Power: 44 kVA x (no. of modules) = XX kVA.
Ex.: 44 x 8 (no. of modules at 40 kW each, 8 = 320kW) = 352 kVA
For the dimensioning of the AC supply line, please observe the following formula:
> Current AC (A) - Specications apply per phase:
32 A x (number of power modules) = XX Ampere.
Ex.: 32 x 12 (no. of modules at 20 kW each, 12 = 240 kW) = 384 Ampere
> Active Power: 21 kW x (no. of modules) = XX kW.
Ex.: 21 x 12 (no. of modules at 20 kW each, 12 = 240 kW) = 252 kW
> Apparent Power: 22 kVA x (no. of modules) = XX kVA.
Ex.: 22 x 12 (no. of modules at 20 kW each, 12 = 240 kW) = 264 kVA
