Switching On the Instrument
Before switching on the instrument, check that all the instructions in the “Basic
Safety Instruction” brochure and safety measures in previous sections are
observed. Also, check if the value on the voltage selector corresponds to the
mains voltage (100 V, 115 V or 230 V).
Fuse rating
The R&S
NGL/NGM uses the same fuse ratings for all mains voltages.
To change power fuse / mains voltage setting:
1. Peel off the yellow label sticker on the AC inlet.
2. Release the latch of the fuse holder which is located at both side of the socket
and pull it out.
3. Pull out the removable part of the fuse holder.
4. Turn this removable part until the correct voltage label (100, 115 or 230) is dis-
played in the window of the holder.
5. Return the fuse holder to its position in the panel.
To switch on instrument:
1. Connect the power cable to the AC power connector on the rear panel of the
R&S
NGL/NGM.
