Safety & Warnings
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 include symbols for observing operating instructions, weight indication for units >18 kg, PE terminal, ground terminal, danger, warning for hot surfaces, shock hazard, and electrostatic sensitive devices.
The unit may be used only in the operating conditions and positions specified by the manufacturer. 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. 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.
For measurements in circuits with voltages Vrms > 30 V, suitable measures should be taken to avoid any hazards. 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 wiring of the unit should only be performed by qualified technical personnel.
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.
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.
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. A safety test must be performed after each replacement of parts relevant to safety.
Ensure that the connections with information technology equipment comply with IEC950 / EN60950. 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. Dispose of them in appropriate containers only. Do not short-circuit the battery.
Equipment returned or sent in for repair must be packed in the original packing or in packing with electrostatic and mechanical protection. Electrostatics via the connectors may damage the equipment. For the safe handling and operation of the equipment, appropriate measures against electrostatics should be implemented.
The outside of the instrument is suitably cleaned using a soft, lint-free dust cloth. Never use solvents such as thinners, acetone or similar, as they may damage the front panel labelling or plastic parts. Any additional safety instructions given in this manual are also to be observed.
