3.6 External residual-current device
The manufacturer does not supply an external residual-current device. If an external
residual-current device is required because of local rules, this section helps you to
select the correct device.
Situation: the local rules require an immunity for short current peaks over PE
during the EV charging process
At the start of the EV charge cycle, a relay switches and engages the AC input power
to the power modules. Incidental current peaks can occur.
A combination of these factors is the source of these current peaks:
• Asynchronous engagement of the phases in the relay
• The electrical capacity of the AC input power part of the EVSE
The amplitude of the current peaks can change. These factors are the source of the
differences:
• The location of the EVSE
• The power grid
• The earth impedance
For the specifications of the residual-current device and the incidental current
peaks, refer to sections 12.6 and 12.9.
