At what locations/sites may be KeContact P20 be installed?
The KeContact P20 is suitable for indoor and outdoor installations. However, several installation instructions and restrictions must be observed. For installation details, please refer to the installation manual in the "General criteria for the site selection" chapter.
Are special tools required for the assembly, installation, and inspection?
For installing the KeContact P20, you will require a drill and an open-end wrench (13mm/M8).
* Flathead screwdriver for supply terminals (blade width 5.5 mm)
* Flathead screwdriver for SELV terminals (blade width 3.0 mm)
* Phillips head screwdriver PH2
* Mounting tools for screw connections M16 (width across flats 20 mm) and M32 (width across flats 36 mm)
* LSA+® insertion tool (optional – versions with PLC/ethernet communication)
Please observe that an electrical inspection is necessary after installing the charging station. This electrical inspection must be carried out in accordance with the respective valid national standards and guidelines.
What additional material is required for the installation?
The KeContact P20 in European versions is turnkey ready with all required installation material supplied.
You can find general information on commissioning in the installation manual in the "Commissioning" chapter.
Where can I find the technical data for the KeContact P20?
You can find the technical data for the KeContact P20 in the installation manual in the "Technical data" chapter.
How do I test the KeContact P20 after installation?
The charging station can be placed into a commissioning mode for supporting the initial system test. During this, a self test of the device is performed (interlocking, contactor activation, current measurement, etc.) and the result is displayed. You can find more detailed information in the installation manual in the "Commissioning mode/self test" chapter.
Can I connect the KeContact P20 to a home network?
KeContact c-series variants can be connected to a home network. The KeContact P20 features a webserver which displays energy and consumption data as well as event and possible error log entries. Moreover, the unit can be externally controlled through a home network using UDP communication. With this feature it is possible to optimize own household energy consumption in combination with photovoltaic systems and other appliances. For further information please see the installation manual chapter “DIPSwitch settings” and the “UDP programmers’ guide” retrievable from the download section at www.kecontact.com.
Can I update the firmware of the KeContact P20?
Yes, this is possible. Firmware updates are even recommended, as outcomes from continuous tests with new car models as well as possible changes in applicable standards result in firmware changes. The latest firmware releases including an update manual can be retrieved from the download section at www.kecontact.com.
Mechanical damage and replacement parts
The device shows damage after unpacking.
If you suspect you have received a defective device, please fill out the accompanying "Repair Order" form and return the device to your dealer or service partner.
Which replacement parts can be ordered?
The design housing, as well as the cable hanger can be ordered as replacement part. Other defective parts on the KeContact P20 must be replaced by KEBA in the course of a "Repair Order" (accompanying form). Please contact your dealer or service partner if you have additional questions.
Connection and installation
How can the KeContact P20 be electrically protected?
The fuse protection of the KeContact P20 always occurs in the local building installation. The fuse protection by circuit line breaker must be done in dependence on the available power in the respective KeContact P20 version (Type 2 socket/cable, Type 1 cable) in accordance with the locally valid guidelines.
Is a 32 A feed-in absolutely necessary for operating the KeContact P20?
No. The KeContact P20 can be configured via DIP switches in the housing to the maximum permitted current (10A, 13A, 16A, 20A, 25A, 32A).
Please observe the deviating requirements for fulfilling "Z.E.-Ready®" (Renault) in the installation manual in the "Deviating requirements for fulfilling the "Z.E.-Ready®" (Renault).
Which fault-current circuit breaker (FI) is used in the building installation?
The selection of the FI circuit breaker type largely depends on the vehicle to be charged. Keba recommends at least using a FI fault-current circuit breaker of Type A, whereby some vehicle manufacturers require a FI fault-current circuit breaker of Type B (universal currents).The following approach is therefore recommended:
* If only one vehicle is charged at the KeContact P20 and the vehicle manufacturer does not require a FI fault-current circuit breaker of Type B, then Type A can be used.
* If different vehicles are charged at the KeContact P20, then a FI fault-current circuit breaker of Type B should be installed to prevent any damage caused by fault current.
Can a KeContact P20 with Type 2 socket/cable also be operated in single phase?
Yes. However, bear in mind that with single-phase operation there is less charging power available for the vehicle as with three-phase operation.
Can a KeContact P20 with Type 1 cable also be operated in three phase?
With a Type 1 plug/cable, charging can only occur in single phase. However, with the KeContact P20 it is possible to connect the additional phases in the connection area. However, the charging only occurs in single phase.
Can the KeContact P20 be converted from single-phase operation (230 V) to three-phase operation (400 V)?
A conversion in this case only makes sense with a KeContact P20 with Type 2 socket/cable. Can a vehicle be charged with a KeContact P20 with Type 1 cable in only single-phase anyway.
How is the connection cable inserted into the KeContact P20?
If the feed line is run on the surface, a cable insertion from above is provided for. If the installation is done with flush mounting, the cable is inserted from the rear into the KeContact P20. Please observe the information in the installation manual in the "Connecting the power supply lines" chapter.
A cable feedthrough from below is not allowed!
What is the purpose of the enable input "IN" (X1)?
The enable input is intended for use with an external potential-free contact. Using the enable input, it is possible to control the charging station using external components (e.g. external key switches, ripple control receiver of the energy supplier, house control, time switches, combination lock, photovoltaic system etc.).
The configuration of the enable input occurs via the DIP switches in the terminal panel. With active enable input, charging is only possible if the enable contact is closed.
What is the purpose of the switch contact "OUT" (X2)?
The switch contact X2 "OUT" is a potential-free signal contact with which an upstream safety device (e.g. circuit breaker or residual current device) can be switched off in the event of a unit fault (contactor contacts welded). For instance, this is a requirement for Renault Z.E.- Ready-compliant installations. Over this relay contact only safety extra-low-voltage <50VAC (0.5A) may be switched. For further information including a connection example please refer to the installation manual in chapter “Switch contact output X2”.
The configuration of the signal contact occurs via the DIP switches in the terminal panel.
How is the Ethernet cabling done in the terminal panel (for versions with Ethrnet communication)?
The KeContact P20 in versions with Ethernet communication (c-series) have two Ethernet connections, one LSA+ connection terminal and an RJ45 socket. Hardwired Ethernet cabling on-site has to be done to the LSA+ connection terminal. The RJ45 socket is merely an interface for debugging functions and for software updates.
The P20 remains black after switching on.
If the P20 does not display anything after switching on, please check the glass tube fuse on the left hand side of the connection area. For replacing the fuse please see the instructions in the installation manual in the “Replacing the fuse” chapter.
The KeContact P20 has a 24 month warranty. Please contact your dealer or service partner for warranty claims.
