2.1 External CT ratio

Ct = External CT primary/secondary ratio
External CT ratio (Ct): 1...9999
(maximum primary current 50000/5A)
On modifying the ratios the power counters are automatically reset.

Phase sequence diagnostic

In the software there is a diagnostic and correction algorithm of the voltmetric and ampero-
metric connection sequence.
The function can be activated on request and password protected: it can display and edit the
wiring sequence with the following limitations:
1) The neutral conductor
(in the 4-wire wirings)
2) There must not be any crossings between the currents
3) The power factor must be between 0.9cap and 0.7ind for each phase
See www.imeitaly.com "TECHNICAL

must be correctly positioned
(terminal 11)
