WARNING: Before connecting the phase and neutral conductors of MAINS,
GENSET and LOAD to the control panel, it is the installer responsibility to check
the type of distribution system of the plant.

the combined neutral and protection function (PEN), IT MUST NOT BE SELECTED.
A wrong or missed neutral conductor connection may cause serious damages to
the Control Panel and to the distribution plants connected to it.
