What to do if Liebert UPS shows 'Short Circuit Recovery - Please Wait'?
If your Liebert UPS displays 'Short Circuit Recovery - Please Wait', wait for at least 30 seconds and then turn the output on.
How to fix Liebert UPS battery module not ready error?
If the Liebert UPS indicates 'Battery Module not ready,' it means the Battery Module is not properly installed. Ensure the module is fully inserted and the fastener is secured.
What to do for Liebert UPS 'Load Exceeds Battery Module Capacity'?
If your Liebert UPS indicates that the 'Load Exceeds Battery Module Capacity', it means the measured load on the output will cause the battery modules to exceed their limits if the UPS transfers to battery mode. You should reduce the UPS’s load or add battery capacity. If external non-modular battery cabinet(s) are added, verify that the UPS’s configuration is set to match the external battery amp-hour rating and charger rating.
What to do if Liebert UPS show 'External Battery Module Warning'?
If your Liebert UPS displays an 'External Battery Module Warning', verify proper connections between the UPS and the Non-Modular Battery Cabinet. Reenter the amp-hour rating for the external battery (set the amp-hour entry to zero and press the return key, then reset it to the appropriate value for the external battery). If the problem persists, the external battery should be replaced.
What to do if Liebert Nfinity says 'Battery Test Weak Battery'?
If your Liebert UPS reports 'Battery Test Weak Battery', depending on the age of the batteries, it may be appropriate to replace all batteries in the system. Schedule a battery test so that the system operation is double-checked once the batteries become fully charged.
What does 'Bypass source not qualified' mean on a Liebert Nfinity?
If your Liebert UPS shows 'Bypass source not qualified', it means the input voltage is not within the specified voltage or frequency range, preventing automatic or manual transfer to bypass. To resolve this, verify the UPS’s configuration for voltage and frequency, check the UPS’s input breaker; or disable this alarm if desired via configuration.
What to do if Liebert UPS says 'Output Off - Output Short Circuit'?
If your Liebert UPS displays 'Output Off - Output Short Circuit', it means a short circuit was detected on the output. Correct the short circuit or extreme overload condition, and then turn the UPS output back on.
What to do if Liebert Nfinity UPS shows 'Output Off- Overload, bypass unavailable'?
If your Liebert UPS shows 'Output Off - Overload, bypass unavailable', reduce the UPS’s output load and verify that the UPS’s bypass source is qualified (amplitude and frequency). Also, verify that the configuration voltage and frequency settings are properly selected.
What to do if Liebert Nfinity shows redundant power alarm?
If the Liebert UPS displays a 'Redundant Power Alarm,' it means that the UPS is no longer redundant. Replace the faulty module to regain redundancy.
