Xantrex Technology GT Series AC Utility Terminals TB1-A, TB1-B, TB1-C, TB1-N, and TB2GND BUS

Safety

4.Open, lockout, and tag the DC Disconnect Switch (S1) on the right door of the Inverter enclosure. See GT100 or GT250 Grid Tie Inverter manual for the location of the DC Disconnect Switch.

CAUTION

Once the DC Disconnect Switch is open, there will be DC voltage on the PV Array side of the switch where TB3, TB4, and TB5(PV GND) are located. This voltage may be as high as the Open-Circuit Voltage of the PV Array and is limited to 600VDC per NEC 690.

5.Using a confirmed, accurate meter, verify all power to the inverter is de- energized. A confirmed, accurate meter must be verified on a known voltage before use. Ensure that all incoming energy sources are de- energized by checking the following locations at all line-to-line and all line-to-ground configurations.
