* Factory data
Diagnostic, Phase sequence correction:
On the device 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) must be
correctly positioned (terminal 11)
2) The power factor must be between 0.9cap and 0.7ind for each
phase. See www.imeitaly.com "TECHNICAL SUPPORT".
