Safety Instructions
1140.0050.82 SI.1 E-1
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.
Safety-related symbols used on equipment and documentation from R&S:
Observe
operating
instructions
Weight
indication for
units >18 kg
PE terminal Ground
terminal Danger!
Shock hazard
Warning!
Hot surfaces Ground Attention!
Electrostatic
sensitive de-
vices require
special care
1. The unit may be used only in the operating con-
ditions and positions specified by the manufac-
turer. Unless otherwise agreed, the following
applies to R&S products:
IP degree of protection 2X, pollution severity 2
overvoltage category 2, only for indoor use, al-
titude max. 2000 m.
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 Vrms
> 30 V, suitable measures should be taken to
avoid any hazards.
(using, for example, appropriate measuring
equipment, fusing, current limiting, electrical
separation, insulation).
3. If the unit is to be permanently wired, the PE
terminal of the unit must first be connected to
the PE conductor on site before any other con-
nections are made. Installation and cabling of
the unit to be performed only by qualified techni-
cal personnel.
4. 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.
5. 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.
6. Units of protection class I with disconnectible
AC supply cable and appliance connector may
be operated only from a power socket with
earthing contact and with the PE conductor con-
nected.
7. It is not permissible to interrupt the PE conduc-
tor intentionally, neither in the incoming cable
nor on the unit itself as this may cause the unit
to become electrically hazardous.
Any extension lines or multiple socket outlets
used must be checked for compliance with rele-
vant safety standards at regular intervals.
8. 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.
9. 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
opening the unit, the latter must be discon-
nected from the supply network.
Any adjustments, replacements of parts, main-
tenance or repair may be carried out only by
authorized 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). continued overleaf

Safety Instructions
1140.0050.82 SI.2 E-1
10. Ensure that the connections with information
technology equipment comply with IEC950 /
EN60950.
11. Lithium 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).
Lithium batteries are suitable for environmen-
tally-friendly disposal or specialized recycling.
Dispose them into appropriate containers, only.
Do not short-circuit the battery.
12. Equipment returned or sent in for repair must be
packed in the original packing or in packing with
electrostatic and mechanical protection.
13. Electrostatics via the connectors may dam-
age the equipment. For the safe handling and
operation of the equipment, appropriate
measures against electrostatics should be im-
plemented.
14. The outside of the instrument is suitably
cleaned using a soft, lint-free dustcloth. Never
use solvents such as thinners, acetone and
similar things, as they may damage the front
panel labeling or plastic parts.
15. Any additional safety instructions given in this
manual are also to be observed.
Caution
Prior to removing the rear feet and taking off the enclosure, put unit onto front handles to
avoid damages to the unit though slipping.
When mounting the tube take care not to damage or pull off cables.

Safety Instructions
1140.0050.82 SI.3 E-1
The instrument contains components which are hazardous to electrostatic exposure and which are marked by the
following symbol:
•To avoid damage of electronic components, the operational site must be protected against electrostatic di-
scharge (ESD).
Wrist strap with cord
Building ground
Floor mat
Ground connection
of operational site
Heel strap
The following two methods of ESD protection may be used together
or separately:
•Wrist strap with cord to ground connection
•Conductive floor mat and heel strap combination
The batteries used in the instrument are high-power lithium cells with a life utility of approx. 5 years. If you do not
handle them properly, there is a danger of explosion. Therefore, observe the following safety instructions:
•Avoid short-circuit and loading of the battery
•Do not expose lithium batteries to high temperature or fire.
•Do not open used batteries
•Keep batteries away from children.
•Replace battery only by R&S type battery (R&S ordering number 0565.1687.00)
•Make sure to connect the battery to the appropriate terminals when replacing
•Lithium batteries are suitable for environmentally-friendly disposal or specialized recycling. Dispose them into
appropriate containers, only.
