If your Ablerex UPS fails to provide battery backup or the backup time is shorter than expected, charge the UPS for 8 hours. If the backup time remains insufficient, contact your local distributor to replace the battery.
What to do if the Ablerex MSII-RT UPS red fault LED lights up?
If the Ablerex UPS red fault LED is lit, first ensure the battery connection is properly secured. Recharge the batteries for 8 hours to see if the UPS functions normally. If the issue persists, reduce the load on the UPS. Check the AC power cord for damage and replace it if necessary. Also, check the EPO terminal for any short circuits and remove any obstructions from the ventilation holes. Ensure the UPS is operating normally; if it's in CVCF mode, turn it off and then on again. When the UPS is in CVCF mode, bypass input is not allowed, so turn off the UPS and bypass input before restarting. If problems persist, seek assistance from your local distributor.
