[. . . ] The devices are equipped with fans to assist dissipation of generated heat: Make sure that the air vents · on the sides of the AC 3200 are not covered or blocked and provide ducts of sufficient size or allow sufficient space to ensure a free air flow between the devices. Regularily clean the air vents on the sides of the AC 3200 with a soft brush. In order to avoid heat accumulation, make sure to install the AC 3200 as the uppermost device. Never stack more than two devices directly one above the other!To ensure that the AC 3200 cannot slip on the surface on which it is placed, four self-adhesive soft rubber feet are supplied. Some surfaces have been treated with varnish, polish or synthetics which might cause stains when they come into contact with other synthetics. Despite a thorough testing of the synthetics used by us, we cannot rule out the possibility of staining. Do not place the AC 3200 on delicate surfaces. 8 Putting the AC 3200 into operation Ensure that the base of the AC 3200 is clean and free from grease before fitting the rubber feet. Fix the rubber feet to the base of the AC 3200 by peeling off the backing paper and fitting them as shown in the diagram on the left. Place the AC 3200 on an even, horizontal surface. When installing the device in a closed or multi-rack assembly, please consider that, during operation, the ambient temperature, the mechanical loading and the electrical potentials will be different from those of devices which are not mounted into a rack. The ambient temperature within the rack must not exceed the temperature limit specified in the AC 3200 specifications. When installing the device in a rack, take good care not to affect the ventilation required for safe operation. If necessary, provide additional ventilation. In order to avoid heat accumulation, make sure to install the AC 3200 as the uppermost device in the rack. Provide for a duct or vent space of 1 U above the AC 3200 to ensure that the heated air can dissipate. Make sure the mechanical loading of the rack is even to avoid a hazardous condition such as a severely unbalanced rack. When connecting the device to the power supply, observe the information indicated on the type plate. If necessary, provide overcurrent protection. Ensure a reliable mains ground connection of the device by taking appropriate measures. When installing the device in a closed or multirack assembly, please note that intrinsically harmless leakage currents of the individual devices may accumulate, thereby exceeding the allowable limit value. [. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Reorient or relocate the receiving antenna. · Increase the separation between the equipment and receiver. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
