This Charge Point is designed to be permanently connected to an AC supply network.
Use provided cable glands in order to maintain the IP protection
MCB RCD 3
The IEC-61851-1:2017 standard indicates that each
plug shall have protections. In case the Charge
Point has no protections inside, they shall be placed
upstream. These protections shall be as follows:
1.Main circuit electrical protections :
-
MCB
(One per each charging outlet ) overload and
short-circuits protection ,must be curve C with gauge
25% higher than the current setup of the charger
controller. with 2P ( 230 Vac in single phase variant) or
4P ( 400 Vac in three phase variant) according to the
standards: IEC 60898-1, IEC 60947-2 or IEC 61009-1.
For example for 32A setup a 40A MCB will be used)
- RCD
(One per each charging outlet) direct and indirect contacts RCD must be at least Type A and with a
sensitivity of 30 mA or RCD type B with the same rating. The gauge of this electric protections must be
according to the current setup of the charge controller . C fault current shall be measured by a RCD type B or
a appropriate equipment that ensures the disconnection of the supply in case of DC fault current above 6 mA.
( eNext Elite may be equipped with and integrated 6mA. DC leakage detection ) With 2P ( 230 Vac in single
phase variant) or 4P ( 400 Vac in three phase variant) according to the standards: IEC 60898-1, IEC 60947-2
or IEC 61009-1
2. Auxiliar Circuit
(Optional just in case of selecting wiring 2A, view pag 19) :
-
MCB
overload and short-circuits protection with 2 Poles 6A
In all cases, coordination with the protections installed upstream must be guaranteed.d
NOTE: According to some national regulations RCD Type B or Type A with 6mA DC leakage detection may be mandatory.
