Putting the SR 2020 D into operation
Rack-mounting
Mounting the antennas
to the front or rear
of the rack
For the best possible radiation power, you should align the
antennas vertically. If this is not possible, use one of the optional
antenna mounts (see “Accessories and spare parts” on
page 25):
Risks when rack mounting the transmitter!
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 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.
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 mains,
observe the information indicated on the type
plate. Avoid circuit overloading. If necessary,
provide overcurrent protection.
When installing the device in a closed or multi-
rack assembly, 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.
CAUTION!
