**) Note: In order for the UPS and power management software to operate normally,
Manual Bypass should always be set to OFF as the load will not be protected by the unit
when Manual Bypass is ON. This is aimed for operating an external maintenance bypass
switch.
***) Note: You should turn UPS off and keep the AC power before you use “Generator”
function. (even you want to select “\Generator\OFF” to back to normal mode).
