Input Voltage Or Frequency Cannot Support Bypass Error!!

[Anonymous user]

We have a UPS 6000 RM XL that we recently installed. Tonight the APC just turned off, after powering it back on and checking the logs we see the following alarms. Please can someone tell me if this is a problem with our power or with our APC.

Critical Alarm:
Input Voltage Or Frequency Cannot Support Bypass
Bypass not in range; high voltage.

Here is a screen copy of the data log page.

Like Erasmus said, you probably have different input/output voltages, which means the UPS will drop the load if forced to go to bypass for whatever reason rather than risk sending dangerous (either abnormally high or low) voltage to your equipment. Complete data logs will provide a more definitive answer.
