Supply of the loads (U1out, U2out)

Connect the devices to be supported to the outputs U1out and U2out. If the external 24 V DC input voltage is lost, the UPS takes over the supply of the devices connected to it thanks to its regulated and buffered 24 V DC output voltage. Use the two 9-pin connectors with push-in connection to wire the CU8130-0240 UPS. The devices connected to the U1out and U2out outputs must not exceed the maximum permissible output current of the UPS of max. 9 A.

Output U1out

The U1out output is primarily intended for connecting an industrial PC. If the industrial PC supports UPS-OCT, output U1out is used to supply the industrial PC and also for bidirectional communication between the UPS and IPC. Observe the following specifications when wiring:

The shielding must be connected on both sides (ground ⏚). In the case of an industrial PC, the connection to the grounding screw is made using an O-ring. The shield must not be connected to GND of the supply connector.
No cable interruptions (e.g. no passive terminals, no distributors).
No parallel loads (e.g. no bridges between Us and Up on the embedded PC, no second industrial PC).

Output U2out

The U2out output is used to supply a second load, e.g. a panel or other 24 V devices.
