1.5.6 Maintenance Bypass Mode
If maintenance and repair for UPS are needed, you can transfer the load to the Maintenance Bypass through
maintenance bypass MCB, and the power to the load is not interrupted. The maintenance bypass MCB is located on
the front panel of the POD, and the capacity meets the requirements of total load capacities. Refer to
