NOTE: The UPS is preconfigured for
TNS earthing system. 3-wire installation using a bonding busbar will
result in a higher leakage current.
-
Remove the indicated plates.
-
Only for TN-C/3-wire earthing system: Move the bonding
busbar from position (A) to position (B) to connect the N busbar to
the G/PE busbar.
