Figure 4: 208 V three-phase, wye-connected
NOTE: With a wye-connected secondary, any two of the
legs can be used to provide 208 V to the IQ EV Charger.
For example, L1 & L2, or L1 & L3, or L2 & L3. Leave the
unused leg open. DO NOT connect it to a Neutral bar or
the Ground. Be sure the center point is grounded to Earth
somewhere in the system.
