11.3.4.2. Procedure for the conguration and storage of the neutral position.
230/400VAC network congurations without neutral conductors.
SI SII
Step 1
It is rst necessary to connect the ATySgM in three-phase
+ neutral (4NBL) to allow conguration of the neutral position
(neutral position is detected at the rst power-up).
Step 2
Connect the autotransformers.

Neutral must be connected as shown in the drawing above in section «10.3.4.1. Auto-transformer
connections», page 29.
11.3.4.3. Reset of neutral position
In case the network is not recognized by the ATySgM (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.
