    The output voltage of the internal power supply is present at the DIRECT OUT (9) connector. With the DPP 4004 this connector’s maximum power handling capacity is 4 A; the DPP 4012 provides 12 A. The output offers internal short-circuit protection and it can be operated without load. It also serves to use the appliance as plain power supply –...
  • Page 6 DYNACORD PROMATRIX SYSTEM capacitive loads connected. This output is controlled by the inputs ON/OFF (TOGGLE) (pin 1 of the remote control connector) or ON/OFF (MODULES) (pin 2). If the ON/OFF (MODULES) input is connected to the ground potential, the MODULES OUT output is constantly activated; otherwise it is constantly deactivated.
  • Page 7 PROMATRIX SYSTEM 4. Mains Voltage Selection (only to be carried out by a qualified service technician) After adjusting the mains voltage, operating the DPP 4004/4012 power supplies with 115 V is also possible. The adjustment has to be carried out before the operation: Remove the cover plate.
