Connecting the Converter to the DC Supply
An external DC power supply and several plug adapters are provided with the instru-
ment. Select the appropriate adapter and attach it to the power supply. To remove a
mounted adapter, press the small button next to the adapter and push the adapter
away from the button.
Connect the power supply to the "9 V / MAX. 1.1 A DC" input on the rear panel (see
Chapter 2.3.2, "Power Supply Connector"
on page 9) and to a power outlet. The
power supply supports input AC voltages between 100 V and 240 V and frequencies
between 47 Hz and 63 Hz.
A lit LED next to the standby switch indicates that the power supply operates appropri-
ately. If neither of the two LEDs is lit, check the fuse of the instrument (see

ZVA-Z500 converters
The external DC power supply units of R&S

Always use the DC power supply delivered with your frequency converter.
