If U
L-PE
does not display – x --, the
protection in the L terminal has been
activated.
If U
N-PE
does not display – x --, the
protection in the N terminal has been
activated.
Case where both protections have
been activated.
In these last three cases, the device must be sent in for repair (see §10.5).
