Normally the EPO connector is closed with a wire on the rear panel. Once the connector is open, the UPS would stop the output until the EPO status is disabled. Enable the EPO status Disable the EPO status 5.3 Battery charge Fully charge the batteries of the UPS system by leaving the UPS system connected to the mains for 1-2 hours.
change within 30 seconds; in resting mode, UPS will detect the change within 3 minutes; (2) Manual test Test the function of the UPS system by pressing the On-Switch “I” for more than 1 second, the UPS would detect whether the battery is connected or the battery is low immediately.
6. Operating Mode for All Models The different string could be displayed on the LCD screen corresponding to their own operating modes, and they are illustrated as the following table. At any time, only one normal operating string or fault string is presented. But the warning, even several warnings could appear in a certain normal operating mode at one time.

The UPS does not have the backup function when it is in bypass mode. The power used by the load is supplied from the utility power via internal filter. 6.4 NO output mode The LCD display in No output mode is shown in the following diagram. The information about the utility power, the battery level, the UPS output and the load level could be displayed.
6.7 Converter mode In converter mode, on LCD display, the mode string is “CVCF”. The UPS would free run with fixed output frequency (50Hz or 60Hz) in converter mode. Once the mains is loss or abnormal, the UPS would transfer to battery mode and the load is supplied continuously by the battery.
7. Setting by LCD Module The output voltage, frequency, Bypass status and operating mode in No output mode or Bypass mode, Two Load segments in output mode, The number of EBM in all mode could be set directly through LCD module. The output voltage could be set to 208V, 220V, 230V and 240V.
