MCB
(Miniature
Circuit
Breaker)
16 A installation: use a 20 A MCB, C-characteristic.
32 A installation: use a 40 A MCB, C-characteristic.
Note:
• The MCB should match the amperage settings of the charging station
and the maximum current available for the station, considering MCB
manufacturer specifications.
• Consider the availability of additional sources of power (for example
solar) together with a dynamic load balancing system (optional).
RCD
(Residual
Current
Device)
40 A, 30 mA AC type A+, high immunity type (for example: HPi, SI, HI, KV, etc.). Elvi
has a 6 mA DC leakage detection internally.
Note:
For a TT or IT electric grid with 230 V from line to line, the charging station must be installed
with one phase being connected to terminal L1 and the other phase being connected to
terminal N.
Power supply wiring
The table below shows how to connect the power supply to Elvi, depending on the specifications of
the power supply cabinet and the version of Elvi.
Option 1: 400 V 3-phase with neutral
For 3-phase use of a Wye-connected secondary, all three
phases (L1, L2 and L3) and neutral must be connected.
Each phase voltage must measure 230 V to neutral.
