If the UPS status is not on-line or if the UPS status is not discharge, the load will be protected during a utility outage.
If the UPS status is automatic voltage regulated (AVR) or if the UPS status is bypass, the load will be powered but not protected from a utility outage.
If the UPS status is shut down, the load will not have power for a certain amount of time regardless of the utility source.
