Lockout and Tag
Safety requirements mandate that this equipment not be serviced while
energized. Power sources for the Xantrex GT100 E must be locked-out and
tagged prior to servicing. A padlock and tag should be installed on each energy
source prior to servicing.
The Xantrex GT100 E can be energized from both the AC source and the DC
source. To ensure that the inverter is de-energized prior to servicing, lockout and
tag the Xantrex GT100 E.
To lockout and tag the Xantrex GT100 E:
1. Open, lockout, and tag the incoming power at the utility disconnect.
2. Open, lockout, and tag the AC disconnect switch on the enclosure. See
Figure 1-4 on page 1–6 for the location of the AC disconnect switch.
3. Using appropriate means, open, lockout, and tag incoming PV circuits.
4. 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.
a) AC Utility Terminals: (Bottom of A, B, C, and N)
See Figure 3-8 on page 3–11 for the location of these terminals.
b) PV Terminals: (PV+ and PV-)
See Figure 3-7 on page 3–10 for the location of these terminals.
WARNING: Shock hazard
Review the system schematic for the installation to verify that all available energy
sources are de-energized. DC bus voltage may also be present. Be sure to wait
the full 20 minutes to allow the capacitors to discharge completely. Schematics
are located inside the front door of the unit.
