The sum of AUX Mains cable length and OUTPUT cable length must be the same for each system. This regulation
prevents unbalanced load shared by two UPSs under by-pass mode (i.e.: AUX Mains cable 1 + OUTPUT cable 1
= AUX Mains cable 2 + OUTPUT cable 2). AUX Mains cable length is the same than Mains cable length.
For equipment with separate AUX Mains, it must be possible to make the neutral of the AUX Mains line electrically
common with the neutral of the main input feed line.
