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:
Fig. 42
1.
Switch off the charging station.
2.
Open the charging station's front cover.
3.
Toggle DIP switch number 1.
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:
Fig. 43
1.
Switch off the charging station.
2.
Open the charging station's front cover.
3.
Toggle DIP switch number 2.
4.
Close the charging station's front cover.
5.
Switch on the charging station again.
6.
The charging station now sets its Ethernet port to:
- Static address: 192.168.0.100
- Subnet mask: 255.255.255.0
If the charger's LAN (Local Area Network) interface has to be
changed back to DHCP mode again, then you can do this from
the web configuration interface (see chapter 8, "Unite Configur-
ation Interface" on page 20).
NOTE
You can also use the factory reset function to set the
LAN interface back to DHCP mode. Note however that
all other parameters will also be reset to factory de-
fault.

Enabling and disabling the web
configuration interface
To enable or disable the Web Configuration Interface:
Fig. 44
1.
Switch off the charging station.
2.
Open the charging station's front cover.
3.
Put DIP switch number 3
– in the OFF position to disable the web configuration in-
terface.
