1.1 Safety information
WARNING!
● Electrical hazard!
Installation, commissioning and maintenance of the charging station must be per-
formed by correctly trained, qualified and authorized electricians(1) who are fully respon-
sible for the compliance with existing standards and installation regulations.
Please observe that an additional overvoltage protection can be required by vehicles or
national regulations.
Also observe that some countries or vehicle manufacturers may require a different trig-
gering characteristic of the fault-current circuit breaker (Type B).
● Only connect voltages and circuits in the right-hand connection area (Ethernet, termi-
nals for control lines) that have a secure separation to dangerous voltages (e.g. suffi-
cient isolation).
Only supply the terminals (X2) from voltage sources which have safety extra-low volt-
age!
● Before commissioning, check all screw and terminal connections for tightness.
● The connector panel cover may never be left open unattended. Mount the connector
panel cover if you leave the charging station.
● Do not carry out any unauthorized conversion work or modifications to the charging
station!
● Repair work to the charging station is not permitted and may only be performed by the
manufacturer (replacement of the charging station)!
● Do not remove any notices on the device, such as safety symbols, warning notices, rat-
ing plates, nameplates or cable markings!
● The charging station does not have its own power switch! The RCD circuit breaker and
the line circuit breaker of the building installation serve as mains disconnector.
● Pull the charging cable out of the plug connection by the plug only and not by the cable.
● Make sure that the charging cable is not damaged mechanically (kinked, pinched or
driven over) and do not allow the contact area to come into contact with sources of
heat, dirt or water.
(1) Persons who, due to their special training, expertise and experience as well as knowledge of current stan-
dards, are able to assess the work performed and the possible hazards.

Installation guidelines
11/44
3 Installation guidelines
3.1 General criteria for the site selection
The charging station was constructed for the indoor and outdoor area. Accordingly it is necessary to ensure
the installation conditions and the protection of the device at the installation site.
● Take into account the local electrical installation regulations, fire prevention measures and accident pre-
vention regulations as well as emergency routes at this site.
● The charging station must not be installed in potentially explosive zones (Ex environment).
● Mount the charging station so that it is not located in the direct flow of passersby and so that no one can
trip over connected charging cables and so that the charging cables do not cover or cross passing
pedestrian and motorized traffic.
● Do not install the charging station at locations where it is exposed to ammonia or ammonia gas (e.g. in
or at stables).
● The mounting surface must be sufficiently stable in order to withstand the mechanical forces.
● Do not install the charging station at locations where falling objects could damage the device (e.g. hung
up ladders or automobile tires).
● According to the product standard, the charging station must be located at a height between 0.4 m and
1.5 m.
We recommend mounting the charging station (height of the socket or parking bay) at a height of 1.2 m.
Observe that national regulations can limit this height.
● The device must not be exposed to direct spray water (e.g. neighboring manual car wash facility, high-
pressure cleaner, garden hose).
● The device should be protected against direct rain as far as possible to prevent icing, hail damage or
similar.
● The device should be mounted so that it is protected from direct sunlight as far as possible to prevent re-
duction of the charging current or interruption of the charging due to excessive temperatures of the
charging station components.
● When set up unprotected against the weather (e.g. outside at a parking space), the charging current
specification is reduced to 16 A if the maximum permitted temperature is exceeded. The charging proce-
dure can also subsequently be switched off.
● For information about environmental conditions, please refer to the Chapter "↪ 5.5 Technical data
[40]".
Observe the internationally valid installation standards (e.g. IEC 60364-1 and IEC 60364-5-52) and
comply with the nationally applicable installation standards and regulations.

Installation guidelines
12/44
3.2 Specifications for the electrical connection
3.2.1 General
The charging station is set to 10 amps in the delivery state. Set the maximum current using the DIP
switches to match the installed line circuit breaker (see Chapter "↪ 4.6 DIP switch settings [31]").
The power supply line must be hardwired to an existing domestic installation and correspond to the nation-
ally applicable legal conditions.
Selection of the residual-current device (RCD):
● Every charging station must be connected via its own RCD. No other circuits may be connected to this
RCD.
● Residual-current device of at least type A (30 mA triggering current).
If the vehicles to be charged are not known (e.g. semi-public area), measures must be taken for protec-
tion where DC residual currents (>6 mA) occur. This can be realized, for example, through device ver-
sion KC-P30-xxxxxxx2, the use of an RCD type specifically intended for electric vehicles or with a RCD
type B. The vehicle manufacturer specifications must also be observed.
● If a charging station is protected with a type B residual-current device, every upstream residual-current
device, even those not assigned to the charging station, must either be type B or equipped with a DC
residual-current detection device.
● The nominal current IN must be selected to match the circuit breaker and back-up fuse.
Dimensioning of the line circuit breaker:
When dimensioning the line circuit breaker also observe the increased environmental temperatures inside
the switch cabinet. Under certain circumstances, this can make a reduction of the charging current specifica-
tion necessary in order to increase the system availability.
● Determine the nominal current according to the type plate specification in coordination with the desired
charging capacity (DIP switch settings for charging current specification) and the power supply line.
Dimensioning of the power supply line:
When dimensioning the power supply line also observe the possible reduction factors and the increased en-
vironmental temperatures in the interior connection area of the charging station (see temperature rating of
the supply terminals). Under certain circumstances, this can lead to an increase of the cable cross-section
and to the adaptation of the temperature resistance of the power supply line.
Mains disconnector:
The charging station does not have its own power switch. The residual current device (RCD) and the line cir-
cuit breaker of the power supply line serve as mains disconnector.

Installation guidelines
13/44
3.2.2 Differing Z.E.-Ready / E.V. Ready requirements
● In the event that the internal switching element (contactor) is no longer able to open, an additional
switch-off capability must be realized. This can be realized with the switch contact output [X2] (for details
see Chapter "↪ 4.5.4 Switch contact output [X2] (excluding e-series) [27]").
● No 13A charging cables may be used.
● For 3-phase connection of the charging station, the device version KC-P30-xxxxxxx2-xxx or at least a
residual-current device (RCD) type A with DC residual-current detection (>6 mA) or a residual-current
device (RCD) type B must be used.
Requirements for the selection of the line circuit breaker:
Charging
current
specification
Line circuit breaker Characteristic
(DIP switch) 1-phase 3-phase

13 A Not allowed
16 A 20 A Not allowed C
20 A 25 A B / C C
25 A 32 A B / C C
32 A 32 A B / C C
The nominal current of the selected line circuit breaker must never exceed the specifications on
the type plate. If the charging current specification and nominal current of the line circuit breaker
are equal, the temperature in the switch cabinet must be specifically observed (thermal derating of
the line circuit breaker).
Mains supply and grounding requirements (Z.E.-Ready/E.V. Ready)
●TT and TN networks: The grounding resistance of the system must be less than 100 Ohm, or lower if re-
quired by national regulations.
●TT networks: With a grounding resistance greater than 100 Ohm, an isolating transformer must be in-
stalled before the EVSE (Electric Vehicle Supply Equipment) installation. The isolating transformer must
then be integrated into a TN grounding system, for which the criteria above applies.
●IT networks: Power supplies with IT grounding systems are forbidden.
● In TT and TN networks, the voltage at the N conductor to PE must not be higher than 10 V.
● If several charging stations are connected to the same power supply, local ground connections must
also be established (at least every 10 outputs).
The maximum grounding resistance for each additional ground connection (measured independently)
must be less than 100 Ohm. All ground connections must be connected to ensure a single potential.
● An excessive proportion of harmonic waves can terminate the charging procedure. The public mains
power supply should fulfill the standards IEC 61000-2-1, IEC 61000-2-2, EN 50160 § 4.2.4 and § 4.2.5
to prevent this problem. The maximum permitted limit of harmonic waves can vary in dependence on the
mains network impedance.

4.1 Installation requirements
● Before beginning the installation, the installation guidelines must be observed.
● Contact person on-site (for access to the mains disconnector in the electrical distribution panel board).
● The electrical connection (power supply line) must be prepared.
● Acclimatization:
For a temperature difference of more than 15°C between transport and installation site, the charging sta-
tion should be allowed to acclimatize unopened for at least two hours.
Opening the charging station immediately can cause water to form inside and lead to damage when the
device is switched on. Under certain circumstances, this damage may not occur until a later point after
the installation.
Ideally, the charging station should be stored at the installation side for several hours prior to installation.
If this is not possible, the charging station should not be stored outside overnight or stored in a vehicle at
cold temperatures (< 5°C).
Tool list
The following tools are required for the installation:
● Flathead screwdriver for supply terminals (blade width 5.5 mm)
● Flathead screwdriver for terminals X1/X2 (blade width 3.0 mm)
● Phillips head screwdriver PH2
