l

When load shedding is activated by closing the contacts
with an external device (such as ripple control receivers),
then the charging current is reduced to 8 A.

l

When load shedding is deactivated by opening the con-
tacts, then the charging process continues at the maximum
available current.

l

In a normal state, when there is no signal connected to the
load shedding input (contacts open between terminal 3
and 4), the charging station supplies the maximum avail-
able current.

Monitoring welded relay contact
failures

In accordance with IEC 61851-1 and EV/ZE Ready requirements,
the Webasto Unite has a welded contactor sensing function. If a
welded contact occurs, then the main board provides a shunt
trip 230 V signal. Note that the CN33 connector output termin-
als must be used to detect welded contact failure for the relays.
In case of a welded contact for the relays, the CN33 connector
output will be 230 V AC. The output which has 230V AC must
be connected to a shunt trip for RCCB triggering as shown be-
low.

The cabling must be done as shown below. The connector
(CN33) terminals must be connected to a shunt trip module.
The shunt Trip module is mechanically coupled to an RCCB (or
MCB) at the fuse box of the charging station.

Resetting RFID card lists and
registering new master RFID cards

This section explains how to reset the local RFID card list and
how to register new master RFID cards in standalone usage
mode. If you have lost your master RFID card and need to
define a new master RFID card, then a qualified service techni-
cian must follow these steps:

.

4.

Close the charging station’s front cover.

5.

Switch on the charging station again.

– When the charger is powered on again, make sure that

all previously stored master card and user card lists have
been erased. If so, then the configuration mode is active
for 60 seconds and the LED indicator is flashing red. The
first RFID card to be registered within 60 second will be
the new 

master

 RFID card. Follow the on-screen in-

structions to register the RFID user card which is used
during the charging process.

If the new master card is not registered within 60
seconds, then the configuration mode is cancelled and
the charging station will behave as an autostart
product.

Configuring a charging station’s
Ethernet port

This section explains how to set the Ethernet port of your char-
ging station to a static IP address in standalone usage mode.
The facture default setting for your charging station is DHCP
mode. If you have to connect to the charging station’s web
configuration interface directly by using a computer (instead of
using your router’s DHCP server), then follow the steps below:
