6. Electrical connections
6.1 Caution
Installation, commissioning, maintenance or retrofitting of the EV charger must be performed by
professional and qualified personnel, who are responsible for complying with existing standards and local
installation regulations.
For safety reasons, an appropriately rated input load disconnector must be provided for each individual
product. No load should be connected directly to the product during installation.
Connect only one EV charger for each circuit breaker and residual current device (RCD) (if required by local
regulations). The circuit breaker serves as a mains disconnector.
Before starting connection operations, ensure that the external AC-line main switch is disconnected, and
circuit breakers are open.
Any operation requiring the main converter box to be opened can lead to electric shock hazards.
6.2 Standard wiring
To connect the EV charger to the electrical panel, professional and qualified personnel should consider the following
guidelines and refer to Table 5.
