The remaining autonomy is less than the set time (standard 2
minutes).
This text alternates with the following screen:
The output voltage can be lost after the indicated time due to
discharged battery. Controlled shutdown of any computer
equipment is absolutely necessary at this point.
(Using the ComConnect communications interface, this
procedure can be initiated automatically on unattended
systems).
If the UPS operates at 100% load, the shut-down procedure
should be completed within 2 minutes after the "battery low"
alarm started.
When the batteries are fully discharged, the UPS is no longer
able to power the connected equipment.
One of the internal battery fuses is defective; this may have
been caused by an internal system failure.
This alarm also appears if no batteries are installed.
The battery extension MCB is in "OFF" position (down):
energy reserve of the battery extension pack is not available.
If not manually operated, this may have been caused by faulty
wiring or battery failure.
The batteries are (almost) chemically worn out.
If the batteries are aged, they must be replaced as soon as
possible to ensure full protection for your equipment (see
chapter 7.3).
The mains voltage or mains frequency are outside UPS input
140V
tolerance (see section 9 - Specifications).
The mains voltage or mains frequency are outside bypass
input tolerance but inside UPS (rectifier) input tolerance (see
section 9 - Specifications).
Bypass operation is inhibited: if for whatever reason the output
converter is not able to deliver the required output, output
power is lost
