Connection layout for e.g. SDA 521:
terrestrial input
SAT inputs
attenuation controls
SAT outputs
terrestrial output
terrestrial slope
DC input 18V
– Potential equalisation (PE) :
Equalise the potential (PE) in accordance with IEC/EN/DIN EN 60728-11.
Connect the PE connection terminal to a PE rail (supplied by customer)
using the PE wire (Cu 4 mm
2
- 9 mm
2
).
– DC input: Via the DC input a 18V (
) voltage is fed in.
– Attenuation controls: Via these controllers the output level of each line can
be adjusted (attenuation of 0…20dB).
– Terrestrial slope correction: Via this controller the slope of the spectrum of
the terrestrial line can be adjusted (attenuation of 0…15dB).
