Batteries contain dangerous substances that can harm the environment if they are disposed of carelessly. ALWAYS
dispose unwanted batteries in accordance with regulations set by local environmental waste disposal organisations.
6 Troubleshooting
If the UPS fails to operate correctly, carry out the following simple checks before you seek trained assistance.
1. Check that the utility mains supply is available and turned ON.
2. Check that the UPS input mains power cable is connected securely.
3. Check that the utility mains supply is within the UPS specified operating range.
4. If the above checks are passed, and the UPS is still not operating, check the mains supply plug-top fuse and the input
fuse (2) on the back of the UPS and replace if found to be ruptured.
Seek trained assistance if the replacement fuse fails immediately the UPS is switched back ON.
5. If all of the above are satisfactory, disconnect the load from the UPS power outlet(s) and check if the unit operates off-
load. If so, then the cause of the problem is likely to be load related.
6. Check that the battery is not discharged or defective.
