Safety instructions

This instrument is built and tested ac cord ing to the current EU-direc­tives and packed in technically safe con di tion. In order to main tain this
condition and to ensure safe op er a tion, the user must follow the hints
and warnings given in this instruction.

During the installation the valid national rules have to be observed.
Ignoring the warnings may lead to severe per son al injur y or substantial
damage to property.

The product must be op er at ed by trained staff. Correct and safe
operation of this equipment is de pend ent on proper transport, storage,
installation and op er a tion.

All electrical wiring must conform to local stand ards. In order to prevent
stray elec tri cal radiation, we rec om mend twisted and shielded input
cables, as also to keep power sup ply cables separated from the input
cables. The con nec tion must be made ac cord ing to the connecting
di a grams.

Before switching on the power supply take care that other equip ment
is not af fect ed. Ensure that the supply voltage and the conditions in the
environment comply with the spec i fi ca tion of the de vice.

Before switching off the supply voltage check the possible effects on
other equipment and the processing system.

WAR NIN G

For electrical installation and com mis sion ing of explosion protected
devices, the data given in the con form i ty cer tifi cate as also the local
reg u la tions for installation of elec tri cal apparatus within explosion pro­ tect ed areas must be considered. The intrinsically safe versions can be
mounted in the explosion hazarded area according to its spec i fi ca tion
only con nect ed to a certifi ed intrinsically safe supply loop with the cor­ re spond ing electrical values.
