Safety

Before you use the instrument, make sure that you read 
and understand all the related data. This includes: all local 
safety procedures, the instructions for the UMM (if 
applicable), and this publication.

WARNING

• Some liquid and gas mixtures are dangerous. This 

includes mixtures that occur because of 
contamination. Make sure that the instrument is 
safe to use with the necessary media.

• It is dangerous to ignore the specified limits for the 

instrument or to use the instrument when it is not in 
its normal condition. Use the applicable protection 
and obey all safety precautions. 

• To prevent a dangerous release of pressure, isolate 

and bleed the system before you disconnect a 
pressure connection.

• Do not use the instrument in locations with explosive 

gas, vapor or dust. There is a risk of an explosion.

• DPI 802/802P only. To prevent electrical shocks or 

damage to the instrument, do not connect more 
than 30V between the terminals, or between the 
terminals and the ground (earth).

Before you start an operation or procedure in this 
publication, make sure that you have the necessary skills 
(if necessary, with qualifications from an approved training 
establishment). Follow good engineering practice at all 
times.

Safety - Marks and symbols on the instrument

The identification on each pressure connector includes the 
type of thread (1/8 NPT, G1/8 ... ).
