Solution

1. Check for proper battery connection, then recharge the batteries for 8 hours to see whether the UPS provides backup power normally; otherwise, consult your local distributor right away.

2. If CB3 is tripped, turn off the UPS completely and keep the CAM switch at position INV before pressing CB3. Then remove some uncritical load at the UPS output end. If there is any damage to the insulation of the AC power cord, please replace it with a new one.

3. Remove the short circuit at the EPO terminal.

4. Remove any objects blocking the ventilation holes.

5. Check that the cooling fans on the rear panel are working normally.

6. Make sure the UPS is operated normally. If it is in CVCF mode you must turn off and turn on the UPS again.

7. All of the parameters except ID Number in a parallel UPS must be the same.

Please refer to section 3.5.5 to set them again.

8. Disconnect and reconnect the RJ45 connector or set a UPS with ID=1.

9. When the UPS is in CVCF mode it is prohibited from having bypass input.

You must turn off the UPS and bypass input and then restart the UPS.

10. Consult your local distributor for help.

If the backup power time is still too short after 8 hours of charging please contact your local distributor for battery replacement.

Refer to section 3.5.6 to troubleshoot the problem; otherwise, consult your local distributor for help.
