11.3 Preventative Maintenance
Perform preventative maintenance on the Alpha Micro 100 every six to 12 months. For mission critical applications
more frequent maintenance should be completed. Proper implementation of the following procedure will ensure that
your system continues to provide reliable backup power in the event of a utility power failure.
11.3.1 Tools and Materials Required
• Labels and marker to number batteries.
• Conductance meter for optional conductance test.
11.3.2 Procedure
1. Inspect the Alpha Micro 100 and wiring for any physical damage. Repair or replace as required.
2. Verify that all connections are securely fastened. Tighten if necessary.
3. Inspect the batteries for cracks or swelling. Replace all four batteries if any of the batteries are cracked or
swollen.
11.3.3 Operational Test
1. Activate the Alpha Micro 100 self-test function.
2. After passing the self-test, disconnect the AC input to the Alpha Micro 100 to trigger the unit into the backup
(Inverter) mode.
3. Let the Alpha Micro 100 operate in the backup mode for approximately 10 minutes and then stop self test.
4. Verify that there is no Low Battery Alarm.
5. Turn the AC breaker on.
For more information refer to section, "7.4 Installing and Wiring the Batteries" on page 22.
CAUTION!
A battery that measures 2V lower than the other three batteries in the string probably
has a shorted cell. Replace all four batteries.
Three batteries in the string measuring the same voltage and one battery measuring
several volts higher indicates an open cell in the battery with the higher reading. Re-
place all four batteries.
