www.pulsar.pl MSRK2012 2.2. Installation procedure. 1. Before installation, cut off the voltage in the 230V power-supply circuit. 2. Install the enclosure or cabinet and lead the cables through the cable ducts. 3. Install the PSU module on mounting pins (the mounting pins should be installed before the assembly of the enclosure/cabinet). 4. Deliver the AC voltage to the ~AC~ terminals. 5. Connect the receivers’ cables to the +AUX, -AUX terminals of the terminal box on the PSU board. 6.
www.pulsar.pl MSRK2012 The power supply technical outputs are open collector (OC) type, as shown schematically below. Fig. 3. Electrical diagram of OC technical outputs. 4. Operation and use. 4.1 Overload or short circuit of the PSU module output. The AUX output of the PSU module is equipped with the PTC polymer fuse assisted protection.
