IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintance (servicing) instructions in the literature accompanying the appliance.

DYNACORD PROMATRIX SYSTEM 1. Utilization The switch-mode power supply rack units DPP4004/4012 are meant for the incorporation into 19" rack shelf systems and serve to supply PA-system installations with the operational voltage of 24 V. The switch-mode power supplies DPP4004/4012 can be operated as single units, together with the PA-system PROMATRIX, or battery-powered, as well as together with the DYNACORD DEM-system. Caution: It is not permissible to expose this appliance to dripping or splashing water.

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. The input is controlled from the DPM 4000 or from an alarm or gong signal module.

DYNACORD 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. - Insert the flat wire bridge on the printed board assembly 86245 into the 115V~ position (red conductor). - With the DPP 4004 additional switching of a switch-mode power supply is necessary.

Only functions when pin 11 carries an analogous supply voltage and when the internal jumper J502 is set to “open”; can be used to remotely switch the PA-system ON/OFF.
