Tests Introduction 5.1.1 Correct testing sequence The EVCC300 incorporates effectively four safety tests (1.1 to 1.4 in the list below), one test to determine if nuisance tripping of an RCD or GFCI is likely to occur (2.1 in the list below) and two operational (charger output enabled) tests (3.1 to 3.2 in the list below) : Warning: It is important for safety reasons to apply these tests in the order shown below: 1. -
Page 17: Tests, Pe (Protective Earth) Touch Pad Test
Tests Tests, PE (protective earth) touch pad test 5.2.1 Description This is the first test that should be performed when using the EVCC300 to test a mode 2 or 3 vehicle charger. During this test the charger is quickly powered up. If there is a ground / earth connection present the instrument will indicate PROCEED. -
Page 18: Interpreting Test Results
Tests Ensure the connection method indicated in the top left corner of the MENU screen is correct. As a reminder the menu screen connection indicator looks like this. In this screen the EVCC300 is set to direct connection. If the red cross is not present the instrument is set for connection to the charger via a tethered cable or plug in charging cable. - Page 19 Tests When an EV charger’s Earth is incorrectly wired to main neutral such as shown below: „ ƒ EV charger’s L -> L EV charger’s N -> N ƒ ƒ EV charger’s PE -> N Neither the voltage measurements nor the touch pad with detect such fault. Failure to follow test instructions on screen may result in hazardous PE wiring undetected.
