1. The unit may be used only in the operating
conditions and positions specified by the manu-
facturer. Unless otherwise agreed, the following
applies to R&S products:
IP degree of protection 2X, Pollution severity 2,
overvoltage category 2, altitude max. 2000 m.
The unit may be operated only from AC supply
mains fused with max. 16 A.
2. For measurements in circuits with voltages Vrms
> 30 V, suitable measures should be taken to
avoid any hazards.
(e.g. use of 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 wiring of the
unit should only be performed by qualified tech-
nical 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
grounding contact and with the PE conductor
connected.
7. It is not permissible to interrupt the PE
conductor 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
relevant 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.
