Safety 1.
instructions
The unit may be used only in the operating conditions and positions specified
by the manufacturer. 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, altitude max. 2000 m.
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.
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 connections are
made. Installation and cabling of the unit to be performed only by qualified
technical personnel.
4.
For permanently installed units without built-in fuses, circuit breakers or
similar protective devices, 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 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 suitable 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
disconnected from the supply network.
Any adjustments, replacements of parts, maintenance 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 (e.
g.
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,
functional test).
10.
Ensure that the connections with information technology equipment comply
with IEC950/EN60950.
