Mounting the receiver into a 19" rack
Do not fit the device feet when mounting the receiver into a
19" rack.
Risks when rack mounting the receiver!
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.
Make sure that the ambient temperature within the rack does not
exceed the permissible temperature limit specified in the specifications
(see page 55).
Ensure sufficient ventilation; if necessary, provide additional ventilation.
Make sure that the mechanical loading of the rack is even.
When connecting to the power supply, observe the information indi-
cated on the type plate. Avoid circuit overloading. If necessary, provide
overcurrent protection.
When rack mounting, please note that intrinsically harmless leakage
currents of the individual mains units may accumulate, thereby
exceeding the allowable limit value. As a remedy, ground the rack via an
additional ground connection.
