3.4.3. Hardware reset
The configurator may determine that a factory reset of the device is necessary. A factory
reset returns the device to its original software at the point of manufacture. Any firmware
updates are not rolled back. The hardware reset button is located in a recessed hole between
the SIM card cradle and the RJ-45 connector as indicated in the diagram below.
To reset the device, it must be connected to mains power and operating in idle state. Any
vehicle connected to the device must be detached. The “reset” button is depressed for at least
60 seconds. The charger is then reconnected and powered on.
Only perform a hardware reset if so, instructed by customer support. As the charger
must be powered when resetting, take proper safety precautions when accessing the
service panel to avoid electrical hazards.
3.4.4. Tamper sensor
Depending on the specific hardware configuration, the charger comes equipped with
either one or two tamper sensors, which are set to detect access to the charger's terminal
panel (optional) and the main electronics compartment (included on all models). The device will
alert the OCPP backend server via a status notification in the event that a tamper sensor is
triggered.
The normal procedures of installation and commissioning do not involve opening the
charger main body; thus, no tamper events are expected to be generated from the main body
sensor (unauthorized access to the main electronics compartment may render the charger
warranty void!).
As the terminal block lid must be removed during installation and troubleshooting, models
which include a terminal panel tamper sensor will generate a tamper event. This "soft" fault does
not preclude the charger from operating and may be cleared via the web client or a power cycle
(hard reset) of the charger. Further tamper events will be reported to the OCPP backend at
every occurrence.
