6.1.1
Output terminals (5) 24 V DC/6 A
The uninterruptible power supply provides a controlled output voltage of 24 V DC,
max. 6 A.
If a load current of approximately 6.8 A is exceeded, the output voltage reduces
at a constant current according to the resistance value of the connected overload.
Connect the load to terminals "+24 V" and "0 V" (provided twice).

6.1.2
Signalling outputs (2) and LED displays (1)
The five signalling terminals (1 - 5) on the 7-pole terminal (2) use potential-free
relay contacts to indicate the device status. These contacts may be subjected to
a maximum load of 30 V DC/1 A.

At an output voltage of around 20 V, the uninterruptible power supply automati-
cally switches off completely (total discharge protection).
