smart Wallbox Error detection and solutions 23
Display Description
Error F17: The temperature monitor has detected a temperature
above 60° Celsius inside the housing. The maximum charging
current will be limited to 6 A.
The LED pulsates green and flashes
red once.
Solution: Charging operations may continue, but the charging output will be reduced. If the error repeats
or persists, the Wallbox must be cooled and/or shaded more effectively at the installation site. If the error
repeats or persists, the Wallbox must be checked and replaced if required: Contact your local smart tech-
nical support.
CAUTION!
If the Wallbox continues to or permanently displays error messages, take the Wallbox out of operation
(see „Taking the product out of and back into operation.“ on page 23) and contact your local smart
technical support. Repairs may have to be carried out before charging procedures can resume.
Checking the internal RCCB.
To ensure the continuing safe operation of the Wallbox, you must manually test the function of the inter-
nal RCCB every 6 months: The RCCB has a button with which to initiate the test function.
PLEASE NOTE!
The internal DC fault current detection conducts a self-test before each charging procedure: a ma-
nual check is not required. In case of an error, the LED display will show an error code (see also from
page 20).
Proceed as follows to test an RCCB:
1. While the Wallbox is ready for operation, remove the housing cover using the key included.
2. Open the flap for the internal safety switches in the electronic components cover.
3. Locate the button engraved
T or marked Test .
4. Press the button: The RCCB must now trip and flick its pivot lever into the center position (connection
to the power supply is interrupted).
5. Now switch the RCCB off completely ( 0 position) and then back on by flicking the pivot lever up into
the I position.
6. Close the flap, replace the housing cover and lock it using the key.
DANGER!
Should the RCCB not trip during testing (pivot level in center position), you must not continue to operate
the Wallbox under any circumstances! Take the Wallbox out of operation and please contact your local
smart technical support.
Taking the product out of and back into operation.
If required, you can take your smart Wallbox Home out of operation. To take the Wallbox out of operation,
please proceed as follows:
1. Switch off the upstream MCB (connection to the electricity grid is interrupted).
2. Open the housing cover of the Wallbox, open the access flap in the electronic components cover and
flick the pivot lever of the RCCB into the 0 (OFF) position.
