Bolt Sizes and Torque Requirements
Table A-5 provides acceptable bolt sizes and torque values for AC terminal
connections.
Table A-6 provides acceptable bolt sizes and torque values to be connected to
the Xantrex inverter’s DC terminal connections.
Uninterrupted Power Supply – UPS
If you have a Xantrex GT500 E or Xantrex GT630 E with optional ride-through
capability you need to install a UPS for operation. You can order an appropriate
UPS from Schneider Electric (part number: 820-0031-01-01) if you are using
230 Vac auxiliary supply voltage in your installation, or you can use any UPS
which meets the requirements in Table A-7 and matches the auxiliary supply
voltage for your installation.
