Routine Maintenance
Routine maintenance can keep the MaxiCharger in safe and stable state.
Clean the cabinet every quarter: tighten the screws and bolts of key parts, and
check whether the wire connection of the MaxiCharger’s connector is burned out. If
any abnormality is found, replace the parts promptly.
Clean the air filter and dust filter at least twice a year.
Test the residual current device once a year.
WARNING
Disconnect the power supply to the MaxiCharger during the entire maintenance
procedure.
Make sure that unauthorized personnel are kept at a safe distance during
maintenance.
Wear proper personal protective equipment, such as protective clothing, safety
gloves, safety shoes, and safety glasses.
If you remove the safety devices for maintenance, reinstall them after completing
the work.
Residual Current Device Maintenance
The internal residual current device (RCD) and residual current breaker with overload
(RCBO) should be tested annually for correct functioning. Before testing, disconnect the
MaxiCharger with the EV and stop any charging processes.
To test the residual current device
Open the front door of the MaxiCharger. When the cabinet door is opened, the
MaxiCharger should not be directly exposed to wind and rain.
The MaxiCharger must be in Standby mode. Tapping the touchscreen will wake
up the MaxiCharger.
Locate the RCD (under the MCCB), and press the Test button of the
MaxiCharger to start the test.
Pass: The MaxiCharger stops operation when the MCCB is set to the
middle position. The MaxiCharger starts operation again when the MCCB
is set to the OFF then ON position.
Fail: There is no response when pressing the Test button. Please
disconnect the AC power of the MaxiCharger and close the cabinet door,
