Selecting a Residual Current Device (RCD)

In installations where the local electric code requires an RCD with a lower leakage

setting, the discharge current might result in nuisance tripping of the external RCD. The

following steps are recommended to avoid nuisance tripping of the external RCD:

Select the appropriate RCD for correct operation of the installation: An RCD with a

rating of 30 mA may actually trip at a leakage as low as 15 mA (according to IEC

61008). High quality RCDs will typically trip at a value closer to their rating.

Configure the trip voltage of the inverter's internal RCD to a lower value than the

trip current of the external RCD. The internal RCD will trip if the current is higher

than the allowed current, but because the internal inverter RCD automatically resets

when the residual currents are low it saves the manual reset.
