1   Scope

  This part of [IEC 62053](/search?q=IEC%C2%A062053)
   applies only to static watt-hour meters of accuracy classes 0,5 and 1 for the measurement
  of DC electrical energy in  DC systems , and it applies to their type tests only. 

    NOTE 1  For other general requirements, such as safety, dependability, etc., see the relevant
     parts of [IEC 62052](/search?q=IEC%C2%A062052) or [IEC 62059](/search?q=IEC%C2%A062059). 


  
  This document
   applies to electricity metering equipment designed to: 

   
      
         

• measure and control electrical energy on electrical networks with two poles where one of the poles is connected to earth and with voltage up to 1 500 V DC;

             NOTE 2  There are DC networks with other configurations or with more than 2 poles (for example
              networks with earth and both a positive and a negative pole). 
         
      
      
         

• have all functional elements, including add-on modules, enclosed in, or forming a single meter case with the exception of indicating displays;

• operate with integrated or detached indicating displays, or without an indicating display;

• be installed in a specified matching socket or rack; ...
