The rating plate contains important information relating to the Wallbox. To see
this rating plate, the cover flap of the Wallbox must be removed as described

8.2 service notes
The Wallbox Duo is designed to require minimal maintenance. It can be
cleaned with common detergents as necessary. Please avoid the use of scrub-
bing powders or detergents with abrasive particles. Calibrated (MID) digital
meters are integrated into the P-CHARGE Wallbox Duo. These have a validity of
8 years and are approved for use by third parties for the calculation of electri-
cal energy. Once this time has elapsed, either a new meter is to be installed,
or the existing device must be audited by the calibration office / bureau of
standards. Please ensure that the device is calibrated regularly to ensure a cor-
rect metering procedure.
Repeated audit tests should be carried out on the P-CHARGE Wallbox Duo
in accordance with BGV A3 or the respective country standards and regula-
tions. The following audit test intervals apply in accordance with the following
extract from the BGB A3.

We recommend that a complete functionality audit of the P-CHARGE Wallbox
Duo be carried out every 6 months to ensure the best possible performance

error is corrected.

poWer failure:
In the event of power failure, the Wallbox Duo auto-
matically shuts down. Once power is reestablished, the Wallbox Duo will
restart by restoring the status saved at the point of outage. The power
backup circuit board in the EWS Box must, however, now be recharged.
This can take approx. 2-3 minutes. The Wallbox is then fully functional.
The control elements of the Wallbox are backlit while the power backup
circuit board is charging.
