3.6 Connecting to power
For safety information, see "Connecting to power" on page 7.
When using the R&S LCX the first time, you can skip Replacing the external
bias fuse and Replacing the line fuse.
If there are any problems during power-on or malfunction of the bias, check
the condition of the mains fuse. Also check the fuse for the external bias
input as described in these instructions. They explain how to check and
change the protective fuses, if necessary.
Replacing the external bias fuse
The bias voltage input of the R&S LCX is protected by a fuse of type
IEC 60127-2/5-F0.5L/250V (order no. 0009.5463.00). The externally accessible
fuse is at the rear panel.
