11.3. Network congurations

11.3.1. Three phase without neutral network
For three-phase networks without neutral (3NBL) 400Vac, a neutral must be recreated to allow the ATyS M to operate at
230Vac. To recreate the neutral, we recommend the use of quantity 2x 400VA auto-transformers connected as shown
below. The neutral position must be dened as neutral on the left or neutral on the right in advance and then wired
accordingly. The example below shows the wiring for a product congured with neutral on the left
A new product must have the neutral conguration pre-programmed as on the left or on the right at the
rst start up using a real (not a recreated) 3 phase + neutral supply.
