Possible Cause
Incorrect communications cabling.
Incorrect baud rate.
Incorrect communication mode.
Load plug(s) not fully seated.
Load circuit protectors tripped.
Power requirements exceed UPS
capacity. If overload is greater than
105%, the alarm beeps every second
and the UPS may switch to Bypass
mode.
The UPS switched to Bypass mode
because the overload increased
(above 105%). The alarm beeps.
The utility line voltage and frequency
are out of specification.
UPS internal temperature is too high.
The alarm beeps and the UPS
switches to Bypass mode for
approximately 10 minutes, allowing
the UPS to cool down.
Weak battery while in Normal mode.
The alarm beeps.
Battery breaker is open (O).
Battery module is not properly
connected to the UPS.
