(1200VA/1800VA/2400VA)

- 4 -

3. Maintenance

Note: When repairing, in order to avoid second damage caused by large current, you must
use DC power supply analog battery to connect to open the inverter, and make sure the
current is below 3A.

4. Fault Symptom

4.1 Inverter Failure in Starting

Possible Reasons as follows

A. Battery Reversely Connected or Battery Volt Abnormal

Check if battery input volt is normal:

B. Battery Reverse Protection Board Fuse Broken

Check if fuse is disconnected

(Figure 1.1)

C. Control Board Auxiliary Power Abnormal

Check if auxiliary power MOS and IC are broken.( Figure 1.7, less possibility, normally
occurs when inverter blast)
