Safety claim 

The  information  in  the  safety  claim  of  the  equipment  documentation  is  intended  to  ensure  that 
equipment is properly installed in order to maintain it in a condition. 
It is assumed that everyone who would be associated with the equipment should be familiar with 
the contents of that safety section, or this safety guide. 
When electrical equipment is in operation, dangerous voltages will be present in certain parts of 
the  equipment  (e.g.  the  input  terminal).  Failure  to  obverse  warning  notices,  incorrect  use,  or 
improper  use  may  endanger  personnel  and  equipment  and  course  personal  injury  or  physical 
damage. 
Before working in the terminal strip area, the equipment must be isolated. 
Proper and safe operation of the equipment depends on appropriate shipping and handling, proper 
storage, installation and commissioning, and on careful operation, maintenance and servicing. 
The operating manual for the equipment gives instructions for its installation, commissioning, and 
operation.  However,  the  manual  cannot  cover  all  conceivable  circumstances  or  include  detailed 
information  on  all  topics.  In  the  event  of  questions  or  specific  problem,  do  not  take  any  action 
without  proper  authorization.  Contact  the  appropriate  WB  technical  sales  office  and  request  the 
necessary information.
