Initial Operation
4.1
Mains Operation
The mains connection is situated on the back of the instrument. The return path switch is operated
by the two-pole mains cable connected to power. The instrument has protection class II (protection
insulation).
Caution!
During installation (e.g. installing the instrument in a 19" rack) the instrument
always has to be disconnected from the supply voltage.
4.2
Assembly of the 19‘‘ Installation Angles
In case the switch SW 024 is to be installed in a 19‘‘ rack, the angles included in delivery have to
be mounted on both sides of the instrument first:
Figure 4-1 Assembly of 19'' installation angles
The assembly shall be made by means of the M4 crosshead screws included in the delivery. Each
angle has to be fixed on the casing with 4 screws as shown above. The screws have to be
tightened firmly.
4.3
Connection to the AMA 310/UMS
The switch SW 024 is to be connected to the AMA 310/UMS via two lines.
The output "Switch Control OUT" of the AMA 310/UMS is to be interconnected with the input
"Switch Control IN" of SW 024 by the USB cable supplied. The front output "OUT" of SW 024 is to
be connected to the HF input "RF-IN" of the AMA 310/UMS by the F cable bridge supplied.
The length of both cable bridges is designed for the standard arrangement provided, here the SW
024 is placed below the AMA 310/UMS or mounted in the 19" rack. In case another assembly is
used, longer cables may be chosen, but make sure that the HF connection is always as short as
possible such that the calibration is not falsified.
