UPS: APC BR650CI
1. Should I always plug the UPS in the wall outlet (even if not turn on or not in use) or not?
2. Should I need to have an AVR (like PSU to UPS to AVR to wall outlet) or ok na ang PSU to UPS to wall outlet, and why? naglibog pa ko ani if recommended daw na naay AVR. By the way, if needed pa ang AVR, please pwede ko makabalo what reliable na brand sa AVR. I don't know unsa ng servo motor. wla man ko kita sa PCX og PCQ ana gud. but mo ask pa ko didto this week.
Thank you daan.
