Safety instructions

This instrument is built and tested ac cord ing to the current EU-direc-

tives 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 injury 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.

WARNING

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.
