UPS chassis ground (or earth).
You must make a good connection to the battery cabinet
chassis ground (or earth). If the battery cabinet has a terminal
strip, you can make the ground connection at the terminal strip
ground (or earth) lug inside the cabinet. If not, you can make
the ground connection at one of the screws on the battery
cabinet; to ensure a good connection, remove the paint under
the cabinet screw.
At the UPS, the procedure for connecting ground depends on
your model.
