Installing the External Residual-current Device
The MaxiCharger includes a Type A RCD integrated in the main breaker, and a RCCB
for the auxiliary path.
The use of external RCD may cause a nuisance tripping during transient conditions such
as when the AC contactor turns on at the start of charging. If an external residual-current
device cannot be avoided due to local regulations, the in-rush current should be
considered when selecting the device.
For the specifications of the residual-current device and the incidental current peaks,
refer to Technical Specifications.
