Mini Wallbox Plus Instructions For Use Manual page 11

3.2 Specifications for the electrical connection
Ensure that the maximum current is set to suit the installed circuit breaker using the Installation Wizard
in the MINI Installation App.
Selecting the residual-current-operated circuit breaker
The connection cable must be wired into the existing building installation and comply with the national
statutory regulations.
The following considerations must be made:
Every MINI Wallbox Plus must be connected its own residual-current-operated circuit breaker
■
(RCCB) externally. No other circuits may be connected to this RCCB.
The RCCB must at least be of type A (30 mA trip current).
■
Additional measures have been taken in the EVSE to protect it from an alternating current (AC)
■
error (< 30mA AC) and direct current (DC) error (< 6 mA DC).
Selecting the circuit breaker
When selecting the circuit breaker, the standard value of the rated conditional residual short-circuit
current shall be 1500A for the MINI Wallbox Plus. Also take into consideration the increased ambient
temperatures in the control cabinet. In certain circumstances this may require a reduction in the
charging current settings to increase the system availability.
Set the rated current to suit the model plate details in conjunction with the required charging power
and the supply cable.
A circuit breaker of type B (40 A min., 400 V min.) must be used.
