Connecting to the DC supply
Use the external power supply and AC power cable delivered with the R&S SZU to supply the required voltage and current. Both values are stated on the casing above the DC power connector, see Figure "Rear view of the R&S SZU".
The input voltage and current must not exceed the maximum values. Using a power supply other than included can damage the R&S SZU.
Plug the DC power cable of the external power supply delivered with the R&S SZU into the DC power connector on the rear panel.
Plug the included AC power cable to the DC socket of the external power supply.
Plug the AC power cable of the external power supply into a power outlet with ground contact. The required ratings are listed in the data sheet.
The R&S SZU does not provide a separate power key. Once connected to the DC supply, the R&S SZU is powered automatically.
Unplug the AC power cable of the external power supply from the power outlet.
On disconnecting, the R&S SZU is powered off.
