5.3.4. Connecting the AC outlet.
Before connecting to the grid, make sure that the voltage and
frequency of the grid meet the inverter's requirements. Please refer
to the technical parameters for more details.
This inverter includes a built-in residual current device (RCD).
If an external residual current device (RCD) is used, a type A device
must be used, with a trip current of 30 mA or more.
The recommended AC cord and switch for the EQX series single-
phase inverter is shown in Tab. 9:
