Power supply unit UPS (77 3400 00)
6.1.1 Output terminals (5) 24 V DC / 12 A
The power supply unit UPS provides a controlled output voltage of 24 V DC, max.
12 A.
If a load current of approximately 12 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.
