1. SAFETY
This apparatus is designated Safety Class I as defined in the IEC Publication 348
This apparatus has been designed and tested in accordance with IEC Publication 348, entitled
"Safety Requirements for Electronic Measuring Apparatus", and has been supplied in a safe
condition. The present instruction manual contains some information and warnings which must be
followed by the user to ensure safe operation and to retain the apparatus in safe condition.
If this apparatus is to be connected to a fixed installation, then before any other connection is
made, the protective earth terminal must be connected to a protective conductor.
Before switching on the apparatus, make sure that it is set to the voltage of the power supply. The
mains plug shall only be inserted in a socket outlet provided with protective earth contact. The
protective action must not be negated by the use of an extension lead without a protective
conductor.
WARNING!
Any interruption of the protective conductor inside or outside the apparatus, or disconnection of the
protective earth terminal is likely to make the apparatus dangerous. Intentional interruption is
prohibited.
When the apparatus is connected to its mains supply, terminals may be live, and the opening of
covers or removal of parts (except those to which access can be gained by hand) is likely to
expose live parts.
The apparatus must be disconnected from all voltage sources before it is opened for any
adjustment, replacement, maintenance or repair.
Any adjustment, maintenance and repair of the opened apparatus under voltage shall be avoided
as far as possible, and, if inevitable, shall be carried out only by a skilled person who is aware of
the hazard involved.
Make sure that only fuses with the required current rating and of the specified type are used for
replacement. The use of makeshift fuses, and the short-circuiting of fuse holders is prohibited.
Whenever it is likely that the protection has been impaired, the apparatus shall be made
inoperative and be secured against any unintended operation and returned to our factory or Agent
for rectification
