9.3.5. Procedure for the configuration and storage of the neutral position
230/400 VAC network configurations without neutral conductors.
SI
SII
Step 1
It is first necessary to connect the HIC4xxA in three-phase + neutral
(4NBL) to allow configuration of the neutral position (neutral position
is detected at the first power-up).
Step 2
Connect the autotransformers.
Neutral must be connected as shown in the drawing above in
section "9.3.4. Auto-transformer connections", see previous
page.

9.3.6. Reset of neutral position
In case the network is not recognized by the HIC4xxA (or in case you would like to change the neutral
position), proceed as follows:
Step 1
Ensure that the product is powered and within voltage limits.
Open the AUTO/MANU cover.
Step 2
Set DIP Switch 1 from 3P to 1P.
Step 3
Set DIP Switch 1 from 1P to 3P.
Step 4
Close the cover.
End of the procedure for detecting the neutral position.
