Installation materials (not provided)
5.2.1. Power cable
The electrician is responsible for selecting the power cable type and size & safety components appropriate for the
specific situation and according to local regulations;
• Wire for the current at the maximum charging speed of the charge point under continuous load;
• Calculate with a power factor of 0.8;
• Calculate with a maximum voltage drop according to the local rules & regulations;
• Use shielded cable for underground cabling;
• Cable thickness: Ø 10 - 22.5 mm;
• Wire cross section
- Solid wires: max. 10 mm2;
- Stranded wires: 6 mm2 with end ferrules.
The charge point can be limited between 6 A and 32 A, as described in chapter 7.3. Switching on the product.
NOTICE
5.2.2. Data cable (optional)
Ethernet cable: Standard CAT5 or CAT6 UTP ground cable with T568B-wired RJ45 connectors;
5.2.3. Earthing
The electrician is always responsible for selecting a cable cross-section appropriate for the specific situation and
according to regulations;
• TN-system: PE-cable (PEN conductor is not allowed);
• TT-system: separately installed earthing electrode < 100 Ohm spreading resistance.
5.2.4. Required nominal input voltage at charge point
• Single phase*: 230 V ± 10 % - 50 Hz
• Triple phase*: 400 V (3 × 230 V + N) ± 10% - 50 Hz
* 3-phase charge point can also be connected to a 1-phase installation. In this case the charge point can
only charge on 1-phase. Only connect L1 on the terminal block of the charge point;
* Some electric vehicles can have a smaller voltage tolerance than 10%. If you experience charging issues
and see that the voltage is around the edges of the 10% voltage tolerance, check if the electric vehicle type
is compatible to charge on your measured voltage.
5.2.5. Electrical protection
• MCB: C-characteristic*;
• RCD: According to IEC 60364-7-722:2015 this charge point must be installed with at least an RCD type A**
• RCBO: with overcurrent- and residual-current detection as described above.
722.531.2.101 Except for circuits using the protective measure of electrical separation, each connecting point shall be
protected by its own RCD of at least type A, having a rated residual operating current not exceeding 30 mA.
Where the EV charging station is equipped with a socket-outlet or vehicle connector complying with the IEC 62196
series, protective measures against DC fault current shall be taken, except where provided by the EV charging station.
The appropriate measures, for each connection point, shall be as follows:
• RCD type B; or
• RCD type A and appropriate equipment that ensures disconnection of the supply in case of DC fault current above 6
mA.
RCDs shall comply with one of the following standards: IEC 61008-1, IEC 61009-1, IEC 60947-2 or IEC 62423.
The charge point is supplied with a DC fault detection device certified according to IEC 62955.
