What to do if my ABB PowerValue 11 RT 6 kVA UPS displays a Battery Disconnect Alarm (Code 11)?

If your ABB UPS displays a Battery Disconnect Alarm (Code 11), it means the battery voltage is lower than the batteries disconnected level defined for this UPS. This could be due to a blown fuse, an intermittent battery connection, or a disconnected battery cable. Verify that all batteries are properly connected. If the condition persists, contact your service representative.
