* Factory setting
Diagnostic, Phase sequence correction:
In the software there is a diagnostic and correction algorithm of the
voltmetric and amperometric connection sequence.
The function can be activated on request and password protected:
it can display and modify the wiring sequence with the following
limitations:
1) The neutral conductor
(in the 4-wire connections)
positioned
(terminal 11)
2) The power factor must be between 0.9cap and 0.7ind for each
phase.
