NOTICE! When mounting the device into 19" equipment racks or cabinets, it is strongly recommended that you: Always fix the device at its front AND rear rack ears using appropriate rack mounting screws and U-washers, as shown in the graphic opposite. Alternatively use shelves fixed to the inner sides of the equipment rack or cabinet. Cooling Thermal conditions are a vital factor to ensure operational safety of the power amplifiers. The amplifiers are equipped with two internal fans that draw cool air from the front into the housing and channel the warm air towards the back of the device. Please ensure that adequate cool airflow is provided. Do not block or cover the front panel air intake or the vents on the rear panel. If the amplifiers are installed in sealed cabinets (e.g. in fixed installations), use additional fan modules with filters that can be easily replaced without opening the sealed cabinets. Do not combine the amplifiers with D6 or D12 amplifiers in one rack. Do not rack up the amplifiers together with other devices producing additional heat with opposing airflow. 14 d&b 40D Start-up manual 1.8 en d&b 40D Start-up manual 1.8 en 5.2 Connections Startup 5.2.1 Mains connection WARNING!
