2.1 Connecting conditions

2.1.1 The test specified must be applied between the parallel-
      blade plug of the mainscord and all accessible metal                                           Clip
      parts of the product.

2.1.2 Before carrying out the test, reliable conductive
      connections must be ensured and thereafter be
      maintained throughout the test period.

2.1.3 The mains switch(es) must be in the "ON" position.
