This manual is for use by qualified installers only
8. Ensure that all incoming energy sources are de-energized by checking the
following PV terminal locations at PV+ to PV-, PV+ to PV ground, and PV- to
PV ground configurations.
• PV Terminals: [TB3, TB4 and TB5 (PV GND)]
See Figure ii on page 1–xv for the location of these terminals.
Interconnection Standards Compliance
The Xantrex GT250 is designed to meet NEC Article 690 and UL1741 2nd Ed
Inverters, Converters, Controllers and Interconnection System Equipment for Use
with Distributed Energy Resources, which includes testing for IEEE 1547.1 and
IEEE 1547.
WARNING: Shock hazard
If a ground fault has occurred, there may be potential between TB4 and GND.
The normally grounded pole may be energized and ungrounded.
Important: Note: If no external disconnect has been installed, do not check
voltage at these points.
Instead, check voltage on the inverter side of DC switch S1.
