In equipment with separate bypass line, an isolation transformer must be placed at either or both of
the UPS mains power supply inputs (rectifier input or static bypass), in order to avoid the direct
connection of the neutral terminal with both mains through the internal wiring of the equipment.
This is only applicable if the power supply comes from two different electrical mains, for example:
- Two different electricity companies.
- An electricity company and a generator set, etc.
