Putting the SR 2020-D into operation
Rack-mounting
CAUTION
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 intrinsi-
cally 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.
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):
• You mount 1 transmitter: Antenna mount AM 2
• You mount 2 transmitters: Antenna mount GA 3030 AM
When using several transmitters simultaneously, make sure that, in order to avoid interfer-
ence, the distance between the antennas is sufficient. If necessary, use active transmitter
combiners (see “Accessories and spare parts” on page 25)
:
• You mount 4 transmitter: Active Transmitter Combiner AC 3
• You mount 8 transmitters: Active Transmitter Combiner AC 3200-II
If you want to mount the antennas outside the rack, you can use remote antennas (see “Ac-
cessories and spare parts” on page 25).
