Maintenance
The power supply and stand by battery(s) should be tested at least once a year as follows:
1. Check LEDs for normal state. AC ON Green, Output ON Yellow, DC ON Red.
2. Check output voltage with normal load. The AQU126-4F should read between 13.60 and 13.85vdc. The
AQU243-4F (&-8F) should read between 27.20 and 27.7vdc. This assures proper voltage to float charge
batteries.
3. With normal load, disconnect AC input. AC LED should be off, all other LEDs should remain normal.
4. Check DC Output to be above 12.1vdc for AQU126-4F and 24.2vdc for AQU243-4F. This checks standby
batteries to be operational. Sealed lead acid batteries have a typical life of 3 to 5 years.
5. Re Apply AC and verify AC LED ON.
