8.1.3. General safety and hazard warnings for all Dewesoft systems 

Safety of the operator and the unit depend on following these rules. 

Use this system under the terms of the specifications only to avoid any possible danger. 

Read your manual before operating the system. 

Observe local laws when using the instrument. 

DO NOT touch internal wiring! 

DO NOT use higher supply voltage than specified! 

Use only original plugs and cables for harnessing. 

You may not connect higher voltages than rated to any connectors. 

The power cable and connector serve as Power-Breaker. The cable must not exceed 3 meters, the

 

 

 

 

 

   

 

 

 

 

 

   

 

 

disconnect function must be possible without tools. 

Maintenance must be executed by qualified staff only. 

During the use of the system, it might be possible to access other parts of a more comprehensive

 

 

   

 

   

 

 

   

 

 

     

 

 

system. Please read and follow the safety instructions provided in the manuals of all other

 

 

 

 

 

 

 

 

 

 

 

   

 

 

components regarding warning and security advice for using the system. 

With this product, only use the power cable delivered or defined for the host country. 

DO NOT connect or disconnect sensors, probes or test leads, as these parts are connected to a

 

 

   

 

 

   

 

   

 

 

 

     

voltage supply unit. 

Ground the equipment: For Safety Class 1 equipment (equipment having a protective earth

 

 

 

 

 

   

 

 

   

 

 

terminal), a non-interruptible safety earth ground must be provided from the mains power

   

 

 

 

 

 

 

 

 

 

 

 

source to the product input wiring terminals. 

Please note the characteristics and indicators on the system to avoid fire or electric shocks.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Before connecting the system, please read the corresponding specifications in the product

 

 

 

 

 

 

 

 

 

 

 

 

manual carefully. 

The inputs must not unless otherwise noted (CATx identification), be connected to the mains

 

 

 

 

 

 

 

 

 

 

   

 

 

circuit of category II, III and IV. 

The power cord separates the system from the power supply. Do not block the power cord, since

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

it has to be accessible for the users. 

DO NOT use the system if equipment covers or shields are removed. 

If you assume the system is damaged, get it examined by authorized personnel only. 

Adverse environmental conditions are Moisture or high humidity Dust, flammable gases, fumes

 

 

 

 

   

 

 

 

 

 

 

or dissolver Thunderstorm or thunderstorm conditions (except assembly PNA) Electrostatic

 

 

 

 

 

 

 

 

 

 

fields, etc. 

The measurement category can be adjusted depending on module configuration. 

Any other use than described above may damage your system and is attended with dangers like

 

 

 

 

 

 

 

 

 

 

   

 

 

 

 

short-circuiting, fire or electric shocks. 

The whole system must not be changed, rebuilt or opened. 

DO NOT operate damaged equipment: Whenever it is possible that the safety protection

 

 

 

 

 

     

 

 

 

 

 

features built into this product have been impaired, either through physical damage, excessive

 

 

 

 

 

 

 

 

 

 

 

 

 

moisture, or any other reason, REMOVE POWER and do not use the product until the safe

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

operation can be verified by service-trained personnel. If necessary, return the product to

 

 

 

 

 

 

   

 

 

 

 

 

Dewesoft sales and service office for service and repair to ensure that safety features are

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

maintained. 

If you assume a more riskless use is not provided anymore, the system has to be rendered

 

 

   

 

 

   

 

 

 

 

 

 

 

 

 

inoperative and should be protected against inadvertent operation. It is assumed that a more

 

 

 

 

 

 

 

     

 

   

 

riskless operation is not possible anymore if the system is damaged obviously or causes strange
