The Delta Maintenance Bypass Box (MBB) is applicable to Delta Amplon UPSs:
RT-15K3P and RT-20K3P. The MBB provides AC input power to the UPS and
connects the output of the UPS to the critical loads and is configurable for single-
phase or three-phase output to suit your needs. When your UPS needs
maintenance, you can switch on the MBB’s manual bypass switch to let the
power be transferred from the inverter output to the manual bypass output to
ensure continuous power supply to your critical loads when the UPS is under
maintenance. Product Introduction
