The PE Pre-Test is a safety feature of the Product. The PE Pre-Test allows
the operator to test the PE conductor for possible presence of dangerous
voltage against earth.
In normal circumstances, the PE conductor is connected to earth and
therefore has no voltage against earth. However, if the PE conductor is not
connected to earth (for example, connected to phase by mistake or PE is
interrupted) the situation may be hazardous.
Operator skin contact is required on the PE PRE-TEST touch sensor (do
not wear gloves) as well as a suitable operator reference to a known earth
ground (through the operator’s shoes or other clothing). Do not touch any
metal parts of the charging station while performing this test. In case of
improper connection to earth (for example, isolated placement of your body)
this indication may be not reliable.
Test procedure:
1. Connect the test adapter to the charging station.
2. Touch the touch sensor with a bare nger. If PE warning indicator (item
2
, Figure 2) illuminates, then dangerous voltage is present at PE
conductor and metal parts of the charging station. Stop further testing
immediately and check for a possible wiring fault of the tested PE
conductor.
W
In case of this error, PE terminal carries hazardous voltage. There is a
high risk of electric shock to the operator and other persons nearby!
Possible errors are:
• PE interrupted / not connected
• PE carries voltage (for example, connected to phase)
WX Warning
• The PE Pre-Test detects the presence of hazardous voltage on
Protective Earth but may not detect an open Protective Earth.
