Connecting AC Power
The switch unit is equipped with an AC power supply connector and can be used
with different AC voltages. The R&S
OSP adapts itself automatically to the volt-
age. Refer to the data sheet for the voltage and frequency requirements. The AC
power connector is on the rear panel of the instrument.
► Connect the R&S
OSP to an AC power supply using the supplied power
cable.
As the instrument's assembly is in line with the specifications for safety class
EN61010, you must connect it only to an outlet that has a ground contact.
For replacing the fuses, refer to the maintenance chapter in the User Manual.
