Waiver of responsibility 

 
The  contents  of  this  manual  abides  by  the  hardware  and  software  used  on  the  current  equipment 
version.  Eventually  there  may  occur  divergencies  between  this  manual  and  the  equipment.  The

Warning 

 
For  more  objectivity  and  clarity,  this  manual  does  not  contain  all  the  detailed  information  on  the 
product  and,  in  addition,  it  does  not  cover  every  possible  mounting,  operation  or  maintenance 
cases. 
 
Before installing and utilizing the equipment, check if the model of the acquired equipment complies 
with the technical requirements for the application

. This checking is the user’s responsibility. 

 
If the user needs more information, or on the event of specific problems not specified or treated in 
this manual, the information should be sought from Smar. Furthermore, the user recognizes that the 
contents  of  this  manual  by  no  means  modify  past  or  present  agreements,  confirmation  or  judicial 
relationship, in whole or in part. 
 
All  of  Sm

ar’s  obligation  result  from  the  purchasing  agreement  signed  between  the  parties,  which 

includes the complete and sole valid warranty term. Contractual clauses related to the warranty are 
not limited nor extended by virtue of the technical information contained in this manual. 
 
Only qualified personnel are allowed to participate in the activities of mounting, electrical connection, 
startup  and  maintenance  of  the  equipment.  Qualified  personnel  are  understood  to  be  the  persons 
familiar  with  the  mounting,  electrical  connection,  startup  and  operation    of  the  equipment  or  other 
similar apparatus  that are technically fit for their work. Smar provides specific training to instruct and 
qualify  such  professionals.  However,  each  country  must  comply  with  the  local  safety  procedures, 
legal provisions and regulations for the mounting and operation of electrical installations, as well as 
with the laws and regulations on classified areas, such as intrinsic safety, explosion proof, increased 
safety and instrumented safety systems, among others. 
 
The user is responsible for the incorrect or inadequate handling of equipments run  with pneumatic 
or  hydraulic  pressure  or,  still,  subject  to  corrosive,  aggressive  or  combustible  products,  since  their 
utilization may cause severe bodily harm and/or material damages. 
 
The field equipment referred to in this manual, when acquired for classified or hazardous areas, has 
its certification void when having its parts replaced or interchanged without functional and approval 
tests by Smar or any of Smar authorized dealers, which are the competent companies for certifying 
that the equipment in its entirety meets the applicable standards and regulations. The same is true 
when converting the equipment of a communication protocol to another. In this case, it is necessary 
sending  the  equipment  to  Smar  or  any  of  its  authorized  dealer.  Moreover,  the  certificates  are 
different and the user is responsible for their correct use. 
 
Always  respect  the  instructions  provided  in  the  Manual.  Smar  is  not  responsible  for  any  losses 
and/or damages resulting from the inadequate use of its equipments. It is the user’s responsibility to 
know and apply the safety practices in his country.
