Liebert UPS User Manual page 14

Models whose part number ends with a "240X" are fitted with a single-phase
isolating output transformer and are separately derived sources. The output
neutral is already bonded to ground on the output terminals with a Bonding
Jumper (see NEC 250-5d, 250-26, 250.91, 250.92). The output L1 and L2
terminals are not connected to the input L1 and L2.
