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:
Pollution severity 2, overvoltage category 2, IP degree of protection 2X, altitude max. 2000 m. The unit may be operated only from supply net- works fused with max. 16 A.
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
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.
