automatically return to the status immediately before the power outage and resumes operation.
Turn the ELB off if you do not want to resume operation by automatic recovery.

If the symptom does not match any of the above, immediately turn the ELB on the main unit off,
pull out the power cord from the power supply and contact your dealer or one of our sales
offices.
