Safety Instructions
This unit has been designed and tested in accordance with the EC Certificate of Conformity and has left the
manufacturer’s plant in a condition fully complying with safety standards.
To maintain this condition and to ensure safe operation, the user must observe all instructions and warnings
given in this operating manual.

1. The unit may be used only in the operating con-
ditions and positions specified by the manufac-
turer. The R&S FSH is protected against drip-
ping water and dust (IP degree 51).
Unless otherwise agreed, the following applies:
pollution severity 2, overvoltage category 2, alti-
tude max. 2000 m powered from AC power sup-
ply, altitude max. 3000 m powered from battery.
The unit may be operated only from supply net-
works fused with max. 16 A.
Unless specified otherwise in the data sheet, a
tolerance of ±10% shall apply to the nominal
voltage and of ±5% to the nominal frequency.
2. For measurements in circuits with voltages V
rms
> 30 V, suitable measures should be taken to
avoid any hazards.
(using, for example, appropriate measuring
equipment, fusing, current limiting, electrical
separation, insulation).
3. For permanently installed units without built-in
fuses, circuit breakers or similar protective de-
vices, the supply circuit must be fused such as
to provide suitable protection for the users and
equipment.
4. Prior to switching on the unit, it must be ensured
that the nominal voltage set on the unit matches
the nominal voltage of the AC supply network.
If a different voltage is to be set, the power fuse
of the unit may have to be changed accordingly.
5. If the unit has no power switch for disconnection
from the AC supply, the plug of the connecting
cable is regarded as the disconnecting device.
In such cases it must be ensured that the power
plug is easily reachable and accessible at all
times (length of connecting cable approx. 2 m).
Functional or electronic switches are not suit-
able for providing disconnection from the AC
supply.
If units without power switches are integrated in
racks or systems, a disconnecting device must
be provided at system level.
6. Applicable local or national safety regulations
and rules for the prevention of accidents must
be observed in all work performed.
Prior to performing any work on the unit or open-
ing the unit, the latter must be disconnected
from the supply network.
Any adjustments, replacements of parts, main-
tenance or repair may be carried out only by au-
thorized R&S technical personnel.
Only original parts may be used for replacing
parts relevant to safety (eg power switches,
power transformers, fuses). A safety test must
be performed after each replacement of parts
relevant to safety.
(visual inspection, PE conductor test, insulation-
resistance, leakage-current measurement, func-
tional test).
7. Ensure that the connections with information
technology equipment comply with IEC950 /
EN60950.
8. NiMH batteries must not be exposed to high
temperatures or fire.
Keep batteries away from children.
If the battery is replaced improperly, there is
danger of explosion. Only replace the battery by
R&S type (see spare part list).
NiMH batteries are suitable for environmentally-
friendly disposal or specialized recycling. Dis-
pose them into appropriate containers, only.
Do not short-circuit the battery.
9. Equipment returned or sent in for repair must be
packed in the original packing or in packing with
electrostatic and mechanical protection.
10.
Electrostatics via the connectors may damage
the equipment. For the safe handling and op-
eration of the equipment, appropriate meas-
ures against electrostatics should be imple-
mented.
