4.5 Connecting the auxiliary voltage

1. Check whether the selected AC supply voltage on the R&S ENV4200 corresponds
to the local AC supply voltage. To change the AC supply voltage, see
the AC supply voltage:"
The R&S ENV4200 can be set for two different nominal AC supply voltages: 115 V
and 230 V. In the 115 V setting, the nominal AC supply voltage range is 100 V to
120 V. In the 230 V setting, the nominal AC supply voltage range is 220 V to 240 V
2. Connect the R&S ENV4200 to the AC supply voltage using the supplied power
cable. If the R&S ENV4200 is correctly connected, one of the four green LEDs for
displaying the test path will light up (depending on the position of the LINE SELEC-
TION rotary switch).
To change the AC supply voltage:
1. Remove the power cable of the AC supply voltage from the R&S ENV4200.
2. Remove the fuse holder in the low-temperature connector on the device's rear
panel.

3. Remove the line voltage selector using a suitable lifting tool such as a screwdriver,
size 1.
4. Set the AC supply voltage by correctly inserting (rotating) the line voltage selector.
5. Close the flap on the power connector.
The selected AC supply voltage is visible in the display window.
