1 Safety and Environment

1.1Safety 1. Do not spill any liquids on the equipment and do not drop any objects through the ventilation slots in the equipment.

2.The equipment may be used in dry rooms only.

3.The equipment may be opened, serviced, and repaired by authorized personnel only. the equipment contains no user-serviceable parts.

4.Before connecting the equipment to power, check that the AC mains voltage stated on the equipment is identical to the AC mains voltage available where you will use the equipment.

5.To avoid the risk of electric shock, make sure to connect the equipment to a grounded power outlet. It is illegal to disconnect the protective ground wire or use a non-standard power plug.

6.Prior to connecting receivers to the equipment, compare the output voltage of the equipment with the operating voltages of all receivers. Only connect receivers operating on the same voltage, type of current (AC or DC), and having the same connector polarity as the outputs on the PSU 4000.

7.The current drain on the DC OUT 1 output of the equipment must never exceed 2.5 A, the current drain on outputs DC OUT 2 and DC OUT 3 must never exceed 2 A.

8.Never short any of the equipment's outputs!

9.Never apply any voltage to any of the equipment's outputs. Never connect any type of power supply to a PSU 4000 output. This may cause damage to both the equipment and the power supply.

10.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.

11.If you will not use the equipment for a long period of time, disconnect the power cable from the power outlet. Please note that the equipment will not be fully isolated from power when you set the on/off switch to OFF.

12.Do not place the equipment near heat sources such as radiators, heating ducts, or amplifiers, etc. and do not expose it to direct sunlight, excessive dust, moisture, rain, mechanical vibrations, or shock.

13.To avoid hum or interference, route all cables away from high-voltage lines of any type.

14.Clean the equipment with a moistened (not wet) cloth only. Be sure to disconnect the power cable from the power outlet before cleaning the equipment! Never use caustic or scouring cleaners or clean- ing agents containing alcohol or solvents since these may damage the enamel and plastic parts.

15.When routing cables, make sure that nobody can trip over them. 16.Do not use any accessories except those recommended by AKG.

17.Do not use the equipment for any applications other than those described in this manual. AKG can- not accept any liability for damages resulting from improper handling or misuse.

1.2Environment 1. When scrapping the equipment, separate the case, circuit boards, and cables, and dispose of all com- ponents in accordance with local waste disposal rules.

2.The packaging of the equipment is recyclabe. To dispose of the packaging, make sure to use a col- lection/recycling system provided for that purpose and observe local legislation relating to waste dis- posal and recycling.
