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
