In Thailand we usually use 3 phases (L1, L2, L3) + Neutral (N) + Ground (PE) with 220V.
A machine imported from Taiwan has four connectors: L1, L2, L3 and Ground (connected to the housing).
It uses this mainly for motor controllers (SDB-075A2), some relays and motors.
The technician setting up the machine says there must be 220V between L1 and L2, 220V between L2 and L3 and 220V between L3 and L1.
I was under the impression that if we wire our incoming Y configuration in a delta way (leave out the N), there would be around 380V between the phases.
How would it have to be connected to have 220V between the inputs?
