    Precautions

    These terms have specific meanings in this manual:

    WARNING information to prevent personal injury.

    information to prevent damage to the equipment.

    important general information.

    Hazard symbols The meaning of hazard symbols appearing on the equipment is as follows:

    Symbol Description

    General hazard

    Toxic hazard

    General conditions of use This product is designed and tested to comply with the requirements of IEC/EN61010-1 ‘Safety requirements for electrical equipment for measurement, control and laboratory use’, for Class 1 portable equipment and is for use in a pollution degree 2 environment. The equipment is designed to operate from an installation category 2 supply. Equipment should be protected from the ingress of liquids and precipitation such as rain, snow, etc. When moving the instrument from a cold to a hot environment, it is important to allow the temperature of the instrument to stabilize before it is connected to the supply to avoid condensation forming. The instrument must only be operated within the environmental conditions specified in Chapter 1 ‘Performance data’ in the Operating Manual otherwise the protection provided by the equipment may be impaired. This product is not approved for use in hazardous atmospheres or medical applications. If the equipment is to be used in a safety-related application, e.g. avionics or military applications, the suitability of the product must be assessed and approved for use by a competent person.

    WARNING Electrical hazards (AC supply voltage)

    This equipment conforms with IEC Safety Class I, meaning that it is provided with a protective grounding lead. To maintain this protection the supply lead must always be connected to the source of supply via a socket with a grounded contact. Be aware that the supply filter contains capacitors that may remain charged after the equipment is disconnected from the supply. Although the stored energy is within the approved safety requirements, a slight shock may be felt if the plug pins are touched immediately after removal. Do not remove covers, no user serviceable parts inside. See list of IFR Ltd International Service Centers at rear of manual.

    Fuses Note that the internal supply fuse is in series with the live conductor of the supply lead. If connection is made to a 2-pin unpolarized supply socket, it is possible for the fuse to become transposed to the neutral conductor, in which case, parts of the equipment could remain at supply potential even after the fuse has ruptured.

  • PRECAUTIONS

    WARNING Fire hazard

    Make sure that only fuses of the correct rating and type are used for replacement.

    If an integrally fused plug is used on the supply lead, ensure that the fuse rating is commensurate with the with current requirements of this equipment. See under 'Performance Data' in Chapter 1 for power requirements.

    WARNING

    Toxic hazards Some of the components used in this equipment may include resins and other materials which give off toxic fumes if incinerated. Take appropriate precautions, therefore, in the disposal of these items.
