Rackmounting
The R&S SMJ can be installed in a rack using a rack adapter kit (Order No. see data
sheet). The installation instructions are part of the adapter kit.
Risk of instrument damage in a rack
An insufficient airflow can cause the instrument to overheat, which may disturb the
operation and even cause damage.
Make sure that all fan openings are unobstructed, that the airflow perforations are
unimpeded, and that the minimum distance from the wall is 10 cm.
2.3.4 Connecting the Instrument to the AC Supply
The R&S SMJ is automatically adapted to the AC voltage supplied. There is no need to
set the voltage manually or change fuses. The AC SUPPLY AND POWER SWITCH is
at the rear of the unit.
► Connect the instrument to the AC power source using the AC power cable deliv-
ered with the instrument.
Note: The instrument is in compliance with safety class EN61010-1.
Connect the instrument only to a socket with earthing contact.
2.3.5 Starting the Instrument
The R&S SMJ comes with or without a power switch, depending on the design of the
otherwise technically equivalent power supply unit.
Switching off the AC power
You can leave the AC power on permanently to preserve your last instrument settings.
Switching off is required only if the instrument must be completely disconnected from
all power supplies.
Starting up instruments with power switch
1. Connect the instrument to the AC supply.
2. To turn the power on, press the main power switch to position I (On).
After power-up, the instrument is in standby or ready state , depending on the state
of the ON/STANDBY key at the front panel of the instrument when the instrument
was switched off for the last time.
3. In case the instrument is in standby mode, i.e. the yellow LED is on, press the ON/
STANDBY key to switch the instrument to ready state.
