User manual AKG PSU 4000

[. . . ] Never connect any type of power supply to a PSU 4000 output. This may cause damage to both the equipment and the power supply. If any solid object or liquid penetrates into the equipment, shut down the sound system immediately. Disconnect the power cable from the power outlet immediately and have the equipment checked by AKG service personnel. [. . . ] This Manual contains important instructions for setting up and operating your equipment. Please take a few minutes to read the instructions below carefully before operating the equipment. Please keep the Manual for future reference. The PSU 4000 is a power supply with three 12 V DC outputs for powering a WMS 4000 multichannel system. Should anything be missing, please contact your AKG dealer. 1 power cable with standard IEC connector The power supply front panel provides the following controls and indicators: ON/OFF: Press this key to switch power to the unit ON. Press again to switch power to the unit OFF. DC OUT 1 - 3: The blue OK LED will be lit for as long as the assigned DC output DC OUT 1, 2, or 3 provides the correct supply voltage for active components. Should the supply voltage at a DC output be shorted or fail (drop below 2 V), the output be overloaded, or the temperature of the unit exceed the acceptable level, the OK LED for that input will extinguish and the red FAIL LED be lit instead. The PSU 4000 rear panel provides the following inputs and outputs: IEC receptacle accepting the matching connector on the supplied power cable. the IEC receptacle incorporates a standard fuse holder with a 2 A slow-blow fuse. The PSU 4000 uses a wide-range power transformer for primary voltages from 90 VAC to 264 VAC. DC OUT 1: DC output jack with a load capacity of up to 2. 5 A for connecting a PS 4000 with an antenna system and up to four SR 4000 receivers (the receivers are powered via the antenna cables) or one other WMS 4000 component (HUB 4000, HPA 4000, CU 4000). DC OUT 2, DC OUT 3: DC output jacks with a load capacity of up to 2 A for connecting a WMS 4000 component (SR 4000, HUB 4000, HPA 4000, CU 4000, PS 4000 with no antenna system). Make sure the total current consumption of all components connected to DC OUT 1 does not exceed 2. 5 A and the total current consumption of all components connected to DC OUT 2 or DC OUT 3 does not exceed 2 A. Higher loads can cause damage to the PSU 4000 due to overheating. Do not connect the unit to power before you have made all audio and DC connections. Operating components on an incorrect voltage may damage both the compponents and the PSU 4000. [. . . ] ) with water to clean the surfaces of the equipment. Never use caustic or scouring cleaners or cleaning agents containing alcohol o solvents since these may damage the enamel or plastic parts. Check ventilator, check connected load, place unit in a cooler location. DC connector on connecting cable is not plugged all the way in. [. . . ]
