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  will  be  associated  with  the  equipment 
will  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 or sales office and request the necessary information.
