Operating Instructions 

General Information : 

The  logical  front  panel  layout  of 

30V-  2A  Power  Supply

  makes  it  easy  to  become 

familiar  with  the  operation  of  the  instruments.  However,  even  experienced  users 
should read the following instructions thoroughly before using the instrument. 

After  unpacking  the  instrument,  check  for  any  mechanical  damage  or  loose  parts 
inside.  Should  there  be  any  transportation  damage,  inform  the  supplier  immediately 
and do not put the instrument into operation.  

Safety : 

The case chassis and all measuring parts are connected to the protective earth contact 
of the  inlet. The mains plug shall only be  inserted  in  a socket outlet provided with  a 
protective  earth  contact.  The  protective  action  must  not  be  negated  by  the  use  of  an 
extension cord without a protective Conductor. 

Warning ! 

Any  interruption  of  the  protective  conductor  inside  or  outside  the  instrument  or 
disconnection  of  the  protective  earth  terminal  is  likely  to  make  the  instrument 
dangerous.  Intentional  interruption  is  prohibited.  The  mains/line  plug  should  be 
inserted before connections are made to measuring circuits. 

When  removing  the  metal  case  or  replacing,  the  instrument  must  be  completely 
disconnected from the mains supply. If any measurement or calibration procedures are 
unavoidable on the opened-up instrument, these must only be carried out by qualified 
personnel acquainted with the danger involved. 

Operating Conditions : 

The  ambient  temperature  range  during  operation  should  be  between  0°-40°C  and 
should not exceed - 20°C or + 70°C during transportation or storage. The operational 
position  should  be  normal  however;  the  ventilation  holes  on  the 

30V,  2A  Power 

Supply 

must not be obstructed. Prior to calibration a preheat run of approximately 30 

minutes is required.
