single-phase. For more information, see Appendix C, “Split-Phase to
Single-Phase Conversion Instructions”.

Conext XW+ Inverter/Charger Grounding
The Conext XW+ is provided with ground terminals that must be reliably
connected to ground (protective earth) by appropriately sized equipment
grounding conductors. System grounding for the AC and DC systems must be
done according to all applicable NEC and local installation codes.
For more information about system grounding, see “Grounding the DC System”
on page 3–8 and “AC Equipment Grounding” on page 3–20.
