Connect the current and voltage terminals. Pay attention to the current polarity. Make
sure that the connection of input and output current terminals and the connection of the
residual current conductor is correct. Check that the input and output logical signals
in the logic diagram for the function under test are connected to the corresponding
binary inputs and outputs of the IED under test.
To ensure correct results, make sure that the IED as well as the test
equipment are properly earthed before testing.

Releasing the function to be tested

Release or unblock the function to be tested. This is done to ensure that only the
function or the chain of functions to be tested are in operation and that other functions
are prevented from operating. Release the tested function(s) by setting the
corresponding Blocked parameter under Function test modes to No in the local HMI.
When testing a function in this blocking feature, remember that not only the actual
function must be activated, but the whole sequence of interconnected functions (from
measuring inputs to binary output contacts), including logic must be activated. Before
starting a new test mode session, scroll through every function to ensure that only the
function to be tested (and the interconnected ones) have the parameters Blocked and
eventually EvDisable set to No and Yes respectively. Remember that a function is also
blocked if the BLOCK input signal on the corresponding function block is active,
