Setup and testing modes

If a lower or higher charging current is provided by the domestic power supply, the factory preset for the Mercedes-Benz Wall­box (16A) can be altered in setup mode via the internal rotary encoders. However, the rated current indicated on the product
label must not be exceeded under any circumstances.

Setup mode

To make adjustments via the rotary encoder, you must first remove the internal electronic components cover of the wallbox:
This is described in steps 7 and 8 page 9 of section “Mechanical installation of the mounting plate”.

DANGER!

After opening the cover for the electronic components, dangerous voltages may be present on the inside of the wallbox
as well as on components you are able to touch. ALWAYS switch off the MCB(s) and RCCB for the wallbox in the domestic
power supply first, and before you continue in setup or testing mode.
Always observe the 5 golden rules of electrical installation:

1. Cut off all voltage sources

2. Secure all cut-off devices

3. Verify absence of voltage

4. Ground and short-circuit

5. Cover or prevent access to adjacent parts under voltage.

Otherwise there is a risk of severe injury or even death through electric shock!

Two rotary encoders (S1 and S3) are located on the main circuit board of
the Mercedes-Benz Wallbox. For normal operations, these must be set to the
0 position. Only the S1 encoder (located on the le hand side of the plan)
is relevant for changing the maximum charging current. Always leave the S3
rotary encoder in the 0 position.

3. Replace the internal electronic compo­nents cover. Close and lock the housing
cover. Switch the power supply back on
via the upstream MCB(s) and RCCB.

The wallbox will now restart in setup mode
and register the settings of the two rotary
encoders.

4. The wallbox now restarts in setup mode.

ca. 10
minutes

If the settings have been successfully
saved after approx. 10seconds, all LEDs
will be on.

5. Switch off the power supply via the up­stream MCB(s) and RCCB.

-

6. Remove the internal electronic compo­nents cover. Set the S1 rotary encoder to
the 0, 1 or F position.

Ensure that the S3 rotary encoder remains
set to the 0 position.

7. Replace the internal electronic compo­nents cover. Close and lock the housing
cover. Switch the power supply back on
via the upstream MCB(s) and RCCB.

During start-up, the wallbox will load the
new settings from the memory and then
return to normal operating mode (see
page 11 and following).

In some circumstances, an error may occur when changing the preset charging current, which will be indicated by the LED
display aer you have switched the power supply to the wallbox back on in step 3.

Error description LED status

• The settings could not be saved in the memory.

• The wallbox was set to an electrical current that is not allowed for this model variant: The

preset current is therefore not altered.

In both cases, please continue with step 6 in order to then restart the wallbox for normal operations.

Testing mode

During initial setup and during later operation, you can check the settings of the Mercedes-Benz Wallbox in testing mode if
there is no vehicle available. To do so, proceed as follows:

Working step LED status Note

1. Switch off the power supply for the wall­box via the upstream MCB(s) and RCCB.

-

2. Remove the internal electronic compo­nents cover. Set the S1 rotary encoder
to the 2, 4 or E position (see table on the
next page).

Leave the S3 rotary encoder in the 0 posi­tion.

3. Replace the internal electronic compo­nents cover. Close and lock the housing
cover. Switch the power supply back on
via the upstream MCB(s) and RCCB.

-

4. The wallbox will now start up in testing
mode.

-

DANGER!

During testing mode, dangerous currents are applied to the charging contacts of the wallbox, which present a danger to life
and limb: do not touch these contacts under any circumstances and proceed with the following actions using extreme cau­tion. Otherwise, there is a risk of severe injury through electric shock or even death!

5. With the wallbox in testing mode, you can
now measure the voltage at each phase
of the charging socket charging connector
. Measuring the signal at the CP contact
(against PE), the frequency, as well as the
duty cycle are also possible.

ca. 10
minutes

The flashing LEDs indicate that the wallbox
is switched on and a voltage is applied to
the charging contacts. Therefore proceed
with extreme caution!

Aer approx. 10minutes, the voltage is
switched off automatically (all LEDs are
illuminated).

6. To terminate testing mode, switch off
the power supply of the wallbox via the
upstream MCB(s) and RCCB.

-

7. Remove the internal electronic compo­nents cover. Set the S1 rotary encoder to
the 0, 1 or F position.

Ensure that the S3 rotary encoder remains
set to the 0 position.

8. Replace the internal electronic compo­nents cover. Close and lock the housing
cover. Switch the power supply back on
via the upstream MCB(s) and RCCB.

During start-up, the wallbox will load the
new settings from the memory and return
to normal operating mode.
