[NOTE] If the UPS is equipped with outlets, those outlets can no longer be used, loads can only be
connected to the MBP outlets or the MBP Output terminal blocks. UPS should be turned off when
UPS is doing maintenance, if load connect to UPS outlet, the load will be lost.
Before turn off UPS, MBP need to set to bypass and keep provide power from utility.
1. Check that the UPS is correctly connected to the MBP63A2
(see previous chapter HARDWIRING THE INPUT/OUTPUT TERMINAL connecting the input and
output but no need to connect MBP detection).
If the UPS is equipped with outlets, those outlets can no longer be used (loads can only be
connected to the MBP outlets or the MBP Output terminal blocks).
