Connecting The R&S Afq To The Ac Supply; Power Fuses - R&S AFQ100A Operating Manual

R&S AFQ100A
Connecting the R&S AFQ to the AC Supply
The R&S AFQ is automatically matched to the applied AC voltage (see rear panel). There is no need to
set the voltage manually or change fuses. The AC supply connector is at the rear of the unit (see
below).
The nominal voltage and frequencies ranges are displayed on the rear panel and quoted in the data
sheet.
Since the instrument is in compliance with safety class EN61010-1, it should only be connected to a
socket with earthing contact.

Power Fuses

The R&S AFQ is fully fused by two fuses IEC127-T4.0H/250 V. The fuses are accommodated in the pull
out fuse holder next to the power connector. Before replacing the fuses, disconnect the power cord from
the R&S AFQ; the fuse box is locked mechanically as long as a power connector is plugged in. Use two
screwdrivers simultaneously to lift the fuse holder below the power connector and pull it out. Use only
fuses of the mentioned type.

Prior to fuse replacement, remove the plug from the AC and DC Power connector.

Use the power cord supplied with the R&S AFQ for connection to the
AC supply. Since the R&S AFQ is designed in line with protection
class I requirements to EN61010 it may only be connected to an
earthing-contact type connector. As soon as the connection has been
established, R&S AFQ outputs a beep. After the start-up is
completed, the ON LED is on.
