Performance description

 
The U 960 is a passive combining network. The devices are used for extension of existing facilities by 
connecting additional channels (e. g. a V 16 base unit).
Some types feature a test point for checking the output signal, attenuated by 20 dB.

Connecting the module

Observe all instructions about installation and mains connection described in the section “Important 
safety information”!

Ensure that the mains voltage, signal sources etc. are properly connected to the device using the corre-
sponding connections. The local mains voltage must be the same as the supply voltage required to 
operate the device (see section “Technical data”“).

Connect input and output jacks of the device via F-connectors of the coax cable.

HINWEIS

During operation of the U 960 all unused inputs of the device must be with a 75 

Ohm terminating resistor.
