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.

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

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.
