What to do if the Mecer ME-1000-WTU icon is flashing and the alarm is sounding twice every second?
This indicates an overload. You should remove excess loads from the UPS output. If the UPS is locked in Bypass mode after repetitive overloads, remove excess loads first, then shut down the UPS and restart it.
Why is the Mecer UPS battery backup time shorter than expected?
The batteries might not be fully charged. Charge the batteries for at least 5 hours and then check capacity. If the problem persists, the batteries may be defective.
What to do if Mecer UPS shows fault code 43?
Fault code 43 indicates that the UPS shut down automatically due to an overload at the output. Remove excess loads from the UPS output and restart it.
How to fix a Mecer UPS with no indication or alarm when the mains is normal?
