AC and DC Disconnect Switches
The main AC disconnect switch is located inside the AC interface enclosure and
the DC disconnect switch is located inside the DC interface enclosure. Additional
external AC and DC disconnecting means, capable of being locked-out and
tagged-out, must be provided as part of the installation, to facilitate safe
servicing of the inverter.
The main AC and DC disconnect switches are each equipped with an auxiliary
contact block which enables the switch to be used as a load break disconnect.
In the event of a fault or if the inverter is shut off for any reason, the DC
disconnect switch automatically opens, and it is capable of breaking the full DC
load current.
For Xantrex GT500 E & Xantrex GT630 E units with UPS backup, the UPS breaker
(-F5) is installed in the center (+H1) enclosure.
All Xantrex inverter enclosure doors must be closed and locked during normal
operation.
WARNING: Multiple sources with risk of electric shock,
explosion, and arc flash
The Xantrex inverter is energized from the PV array, from the AC grid, and from an
auxiliary AC source (backed up with a Xantrex UPS for Xantrex GT500 E &
Xantrex GT630 E units with low-voltage ride-through capability). All 3 sources
(4 including a Xantrex UPS) must be disconnected, locked-out and tagged-out,
and all circuits tested to verify that the inverter is fully de-energized, according to
the procedure on page viii, before servicing or maintenance. Opening the AC
and DC disconnect switches on the inverter does not remove all power from the
inverter. Wait 20 minutes for the DC bus capacitors, located within the cabinet, to
discharge after removing power.
