R&S HZ-9

2 Putting into Operation

Prior to putting the power supply into operation, it is necessary to check whether the
line voltage that is set on the power supply corresponds to the local line voltage.
The R&S
voltage: 115 V and 230 V. In the 115 V setting, the nominal line voltage range is 100 V
to 120 V. In the 230 V setting, the nominal line voltage range is 220 V to 240 V.
Make sure to read and understand the basic safety information in this manual before
setting the power supply to another line voltage or replacing a fuse.
The F101/F102 line fuses are dimensioned to provide protection against overcurrent
situations and short-circuits in both voltage ranges.
The line fuse may be replaced only by an authorized Rohde & Schwarz service
center.
The procedure for replacing the fuse is described in section 4.1.1
Procedure for adjusting the line voltage:
1. Open the cover for the power connector on the power supply's rear panel
(it can be opened only when the power cable is not connected).
2. Remove the line voltage selector using a suitable lifting tool such as a screwdriver,
size 1.
3. Set the line voltage using the line voltage selector.
4. Close the power connector cover.
The desired line voltage must be visible in the display window.
The power supply is connected to the line via the power plug and powered on using
the switch on the rear panel. The LED on the front panel shows the power supply's
current operating state.
