Support Load Information

If the UPS status is on-line or if the UPS status is discharge, the load will be protected during a utility outage.

If the UPS status is automatic voltage regulate (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.
