If it is found that this plug is not compatible with the available wall outlet, the outlet receptacle should be changed. In some cases, new service wiring must be installed. 4.9.1 If the service wiring has been[...]

5.1.1 Sleep Mode While in the sleep mode of operation, the UPS’s display is inactive and no voltage is present at the output. The UPS enters the sleep mode following a 5 minute interval when no commands are given while in the standby mode (see following section). Following a 5 minute interval, the UPS will enter the sleep mode from the on- batter[...]

5.1.5 Bypass mode When in the bypass mode of operation, the load is supplied power conditioned by the Isolation Unit. However, the load will not be protected from utility voltage sags, swells or blackouts. The UPS will automatically transfer to bypass operation when a failure occurs within the Electronics Unit. Detected EU failures include blocked [...]
