Operational Safety Procedures
Never work alone when servicing this equipment. A team of two is required
until the equipment is properly de-energized, locked-out and tagged, and
verified de-energized with a meter.
Thoroughly inspect the equipment prior to energizing. Verify that no tools or
equipment have inadvertently been left behind.
Lockout and Tag
Safety requirements mandate that this equipment not be serviced while
energized. Power sources for the Ethernet Communications Kit must be
locked-out and tagged prior to servicing. A padlock and tag should be
installed on each energy source prior to servicing.
The Inverter 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 Inverter using the following procedure.
1. Turn the Inverter main ON/OFF switch (S3) to the OFF position. This
stops the inverter from exporting power to the AC utility grid.
2. Open, lockout, and tag the incoming power at the utility main circuit
breaker.
3. Open, lockout, and tag the AC Disconnect (CB1) on the left door of the
Inverter enclosure. See your GT100 or GT250 Grid Tie Inverter manual
for the location of the AC Disconnect.
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 five minutes to allow the capacitors to discharge completely
