8.1. Overview of maintenance work
For the safe operation of the charging station, regular maintenance or control of the safety
equipment is required. All the points listed below are considered mandatory and must be
carried out by the operator at the intervals described.
Table 25 gives an overview of the required maintenance work. Depending on the individual
operating conditions of the hypercharger, further maintenance work may still be necessary
so the list below cannot be considered complete.
Replacement of the complete charging cable set
After 10000
charging
cycles
Function test of residual current circuit breaker
Main switch, voltage
release switch
Verify the correct function
Verification of protective
measures
With the charging station switched off, check the
resistance between the ground of the supply and all
externally accessible, non-insulated cabinet parts
(housing, add-on parts, screws)
Check for cleanliness and
condensation
Check if the interior of the control cabinet is clean
and without any traces of condensation.
Check the water run-off on cable plug holder and AC-
socket.
Check the seal for damage and correct positioning.
Random or complete testing of tightening torques at
terminals and mechanical screw connections.
Check the surge arrester for full function
Check the cooling liquid level (fill level indicator)
Concentration of cooling
liquid
Check the concentration (test with refractometer) of
the coolant liquid.
If the concentration is below 50 %, this can be
remedied by adding coolant concentrate.
Check the pH (optimal value - pH between 8 and 9)
of the coolant liquid.
If the pH is below pH 7.7, replace the coolant liquid.
Replacement of the majority of cooling liquid is
sufficient to ensure protection.
