9.2.2. DC Power Cord Connection
Please ensure that during the DC connection procedure, there is no power flowing from the external
DC power source to the KISS 4U Short V2 system.
1. Prepare two isolated wires (minimum cross section of 2.5 mm 2 for the +24VDC PSU and minimum cross section of 1.5
mm 2 for the -48VDC PSU) with attached ferrite core (refer to the subsection 9.2.1 “Attaching the Ferrite Core”),
according to the connectors of the screw terminal.
2. Loosen the two cross-head screws of the screw terminal so that you can insert the stripped ends of the wires. Pay
attention to the polarity of the wires.
3. Fasten the cross-head screws firmly.
4. Cover the connectors of the screw terminal with the protective cover available.
After attaching the cables to the terminals of the DC PSU (+24VDC or -48VDC) always operate the
DC versions of KISS 4U Short V2 systems with the protective cover provided.
5. Prepare the other ends of the wires according to the terminal of the DC power source.
6. Connect the wires prepared to the DC power source. Pay attention to the polarity of the connectors. The DC power
source has to be switched off.
