5.4Rectifying Alarm Messages

Following actions may rectify alarm:

Check local utility supply. Fuses may be blown or supply switched off accidentally

Check if UPS cooling air intake is blocked

Check if load exceeds maximum output capacity

If, with utility power switched on, there is no UPS output voltage - and an attempt to restart the UPS is in vain - use the external service bypass switch to bypass UPS

1.“Battery weak” message appears: Reset “battery weak” signal according to section 4.0 Parameter Settings and initiate battery capacity test according to Section 6.3. Battery Capacity Test. Make a record of obtained back-up time and use battery monitor to reset alarm. Leave the UPS to recharge battery for at least 16 hours. Start up second battery test without changing the load. If the test result shows improved back-up time, continue the test series until no or just insignificant improvements are obtainable. If battery is still weak - call for assistance.

2.“Battery Defective” message appears: Call for assistance. See section 8.0 “How to contact APC”.
