SAFETY CONSIDERATIONS

GENERAL - This is a Safety Class I instrument (provided with terminal for protective earthing).

OPERATION - BEFORE APPLYING POWER verify that the power transformer primary is matched to the available line voltage, the correct fuse is installed, and Safety Precautions are taken (see the following warnings). In addition, note the in- strument’s external markings which are described under "Safety Symbols."

∙Servicing instructions are for use by service-trained per- sonnel. To avoid dangerous electric shock, do not perform any servicing unless qualified to do so.

∙BEFORE SWITCHING ON THE INSTRUMENT, the protec- tive earth terminal of the instrument must be connected to the protective conductor of the (mains) powercord. The mains plug shall only be inserted in a socket outlet pro- vided with a protective earth contact. The protective action must not be negated by the use of an extension cord (power cable) without a protective conductor (grounding). Grounding one conductor of a two-conductor outlet is not sufficient protection.

∙If this instrument is to be energized via an auto-trans- former (for voltage reduction) make sure the common ter- minal is connected to the earth terminal of the power source.

∙Any interruption of the protective (grounding) conductor (inside or outside the instrument) or disconnecting the pro- tective earth terminal will cause a potential shock hazard that could result in personal injury.

∙Whenever it is likely that the protection has been im- paired, the instrument must be made inoperative and be secured against any unintended operation.

∙Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be used. Do not use repaired fuses or short circuited fuse- holders. To do so could cause a shock or fire hazard.

∙Do not operate the instrument in the presence of flamma- ble gasses or fumes. Operation of any electrical instru- ment in such an environment constitutes a definite safety hazard.

∙Do not install substitute parts or perform any unauthorized modification to the instrument.

∙Adjustments described in the manual are performed with power supplied to the instrument while protective covers are removed. Energy available at many points may, if con- tacted, result in personal injury.

∙Any adjustment, maintenance, and repair of the opened in- strument under voltage should be avoided as much as possible, and when inevitable, should be carried out only by a skilled person who is aware of the hazard involved.

∙Capacitors inside the instrument may still be charged even if the instrument has been disconnected from its source of supply.

SAFETY SYMBOLS

Instruction manual symbol. The product will be marked with this symbol when it is necessary for the user to refer to the instruction manual in order

to protect against damage to the product.

Indicates hazardous voltages

Earth terminal (sometimes used in manual to in- dicate circuit common connected to grounded chassis).

The WARNING sign denotes a hazard. It calls attention to a procedure, practice,

or the like, which, if not correctly per-

formed or adhered to, could result in personal injury. Do not proceed beyond a WARNING sign until the indicated condi- tions are fully understood and met.

The CAUTION sign denotes a hazard. It

calls attention to an operating procedure, practice, or the like, which, if not cor-

rectly performed or adhered to, could result in damage to or destruction of part or all of the product. Do not proceed be- yond a CAUTION sign until the indicated conditions are fully understood or met.
