Risk of injury
The feet may fold in if they are not folded out completely or if the instrument is shifted.
Fold the feet completely in or completely out to ensure stability of the instrument and
personal safety. To avoid injuries, never shift the instrument when its feet are folded out.
When the instrument is standing on its folded-out feet, do not work under the instrument
and do not put anything under it, otherwise injuries or material damage could occur.
The feet may break if they are overloaded. The overall load on the folded-out feet must
not exceed 500 N.
Rackmounting
The R&S SMU 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
For rack installation, make sure that all fan openings are unobstructed and that the airflow
perforations are unimpeded. This helps to prevent the instrument from overheating.
2.3.3 Connecting the Instrument to the AC Supply
The R&S SMU 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 delivered
with the instrument.
Note: The instrument is in compliance with safety class EN61010-1.
Connect the instrument only to a socket with earthing contact.
2.3.4 Starting the Instrument
The R&S SMU 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.
