Sennheiser AC 3200 Instructions for Use - Page 61

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. Rack-mounting CAUTION! Risks when rack mounting the AC 3200! 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. Avoid circuit overloading. 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. As a remedy, ground the rack via an additional ground connection. 9
