MAINTENANCE BYPASS
Riello UPS offers several maintenance bypass solutions with two poles and four poles suitable for single and three-phase applications. These devices are equipped with three switches to completely isolate the UPS in case of maintenance needs, keeping, at the same time, the load supplied by the mains without any interruption.
All the operations are done safely, thanks to a dedicated auxiliary contact which provides the status of the MBB to the UPS, avoiding any simultaneous supply from the manual bypass and inverter. Riello UPS offers a wide range of external bypasses and static switches for UPS up to 800 kVA and for parallel systems up to 6.4 MVA.
