3.2.6 Installation with automatic PE-neutral switching
In certain applications, it is desirable to keep the neutral upstream and downstream
of the UPS separated (C) while re-establishing the earthing system (TN-S, TT or
TNC-S) in the absence of voltage at the input. This can be programmed by the
configuration via the control panel. This modification must be carried out possessing
technical knowledge, at the responsibility of the installer and in conformity with the
applicable regulations and standards.
