1.2 Unpacking
While unpacking, check the package contents for com-
pleteness (measuring instrument, power cable, product
CD, possibly optional accessories). After unpacking, check
the instrument for mechanical damage occurred during
transport and for loose parts inside. In case of transport
damage, please inform the supplier immediately. The
instrument must not be operated in this case.
1.3 Setting Up the Instrument
The instrument can be set up in two different positions:
The front support feet are mounted as shown in g. 1. The
front panel of the instrument points slightly upwards (at an
angle of approximately 10°). If the front support feet are
collapsed (see g. 2), it is possible to securely stack the
instrument with other ROHDE & SCHWARZ instruments.
If multiple instruments are stacked, the collapsed support
feet are positioned in the locking mechanism of the instru-
ment beneath, preventing unintended movement (see
g. 3). Be sure to never stack more than three measuring
instruments as an exceedingly high instrument stack may
become instable. Additionally, operating all instruments
simultaneously may generate too much heat.

1.4 Transport and Storage
Please keep the original packaging for possible shipping at
a later point. Damage during transport due to inappropriate
packaging is excluded from the warranty. The instrument
must be stored in dry, closed indoor premises. If the in-
strument was transported under extreme temperatures, it
is advisable to allow a minimum of two hours to reach the
appropriate temperature before operating the instrument.
1.5 Safety Instructions
This instrument was built in compliance with VDE0411 part
1, safety regulations for electrical measuring instruments,
control units and laboratory equipment. It has been tested
and shipped from the plant in safe condition. It is in
compliance with the regulations of the European standard
EN 61010-1 and the international standard IEC 61010-1. To
maintain this condition and to ensure safe operation, the
user must observe all instructions and warnings given in
this operating manual. According to the regulations of
protection class 1, all casing and chassis parts are con-
nected to the protective earth conductor during operation.
If uncertainty exists about the function or safety of the
power sockets, the outlets must be examined in accor-
dance with DIN VDE 0100, part 610.
❙ The available mains voltage must correspond to the
values specied on the instrument label.
❙ The instrument may only be opened by fully trained
personnel.
❙ Prior to opening, the instrument must be turned off and
isolated from all circuits.
In the following cases, remove the instrument from opera-
tion and secure it against unintentional operation:
❙ Visible damage to the instrument
❙ Cable damage
❙ Fuse holder damage
❙ Loose parts in the instrument
❙ The instrument is no longer working
❙ After an extended period of storage under unfavorable
conditions (e.g. outdoors or in damp rooms)
❙ Rough handling during shipment.
Prior to switching on the product, it must be ensured that
the nominal voltage setting on the product matches the
nominal voltage of the AC supply network. If it is neces-
sary to set a different voltage, the power fuse of the prod-
uct may have to be changed accordingly.
It is prohibited to disconnect the earthed protective
connection inside or outside the instrument!
Exceeding the Low Voltage Protection!
For the series connection of all output voltages, it is pos-
sible to exceed the low voltage protection of 42 V. Please
note that in this case any contact with live components
is life-threatening. It is assumed that only qualied and
trained personnel service the power supplies and the
connected loads.
