5.2 SITE PREPARATION
Once the local conditions are verified is time to set up the site in order to be ready for the installation of the
EFAPOWER EV-HC Station.
5.2.1 UPSTREAM WIRING INFORMATION
The power feeding of the EFAPOWER EV-HC with origin on the LVDB (low voltage distribution board) must be
done with dedicated wiring (line(s), neutral and earth conductors only used to supply the equipment) and
protected by a circuit breaker and a voltage suppressor, please refer Figure 7 and Figure 8.
Depending on the output of the Unit, we can have several scenarios for the circuit breaker to be installed in the
distribution board for each Unit. The appropriate circuit breaker is represented in Table 3.
NOTES
Unless it’s required by local code it’s not necessary to install a residual-current device (RCD) for
EFAPOWER EV-HC Station as it is already installed inside the unit.
