Installation And Tests - SENEC Wallbox pro s Manuel D'instructions

• Check whether the charging system housing,
the connecting cable, the charging coupler and
the connections are undamaged.
• Hold the plug connection of the charging system
only by the charging coupler, not by the charging
cable.
• Make sure that there are no tripping hazards,
e.g. due to the charging cable.
During the charging process
• Keep unauthorised persons away from the
charging system.
• Never clean or wash the vehicle using high-pres-
sure cleaning equipment while it is connected to
the charging system, because the plug connec-
tion is not resistant to pressurised water.
In case of malfunctions or failure of the charging
system
• Disconnect the charging system from the power
supply by switching off the respective circuit
breaker in the building's electrical cabinet. Affix
a sign with the name of the person authorised
to switch the circuit breaker back on.
• Notify a qualified electrician without delay.
Electrical equipment
• Keep the charging system housing closed
at all times.

Installation and tests

Information for selecting the protective devices for
basic and fault protection with respect to direct and
indirect contact:
• Electrical circuit breakers
The charging system must be protected with
circuit breakers in compliance with the respective
national regulations. The required protec-
tion depends on factors such as the required
switch-off time, internal network resistance,
conductor cross-section, cable length and the
set power of the charging system. The cable
short-circuit protection must feature a character-
istic which permits a current eight to ten times
the value of I and does not exceed a maximum
nom
rated current of 16 A, depending on the set power
of the charging system.
Use exclusively circuit breakers with a rated
breaking capacity of 6,000 A. The circuit breaker's
I²t value must not exceed 80 kA²s.
• Residual current device
For reasons of personal safety, connect a dedi-
cated RCD in series with each Wallbox. For this
purpose, use at minimum an RCD type A with
an I value of 30 mA AC.
ΔN
DC residual current detection (IEC 62955)
•
The charging system features 6 mA DC residual
current detection. The charging system will
switch off if the residual current reaches or
exceeds 6 mA DC. Please refer to the Diagnostics
chapter for more information.
• Information about initial tests after installation
and repeat tests
National regulations could require testing the
charging system before start-up and at regular
intervals. Perform these tests in compliance
with the applicable regulations. Instructions on
performing these tests are provided below.
• PE conductor test
Measure the PE conductor continuity after
installation and before switching the device on
for the first time. To do this, connect the charging
coupler to a test adapter for vehicle simula-
tion according to EN 61851-1. Measure the PE
conductor resistance between the PE conductor
socket of the adapter and the connection point
for the PE conductor in the building's electrical
cabinet. For a total cable length (connecting
cable of the charging system and vehicle
charging cable) of up to 5 m, the PE conductor
resistance must not exceed 300 mΩ. If the cables
are longer, allowances must be added in accord-
ance with the applicable national regulations. In
any case, the resistance must never exceed 1 Ω.
• Insulation test
The charging system is equipped with a discon-
necting relay and therefore requires two insula-
tion measurements. The charging system must
be disconnected from the mains for this purpose.
Therefore, switch off the mains voltage at the
circuit breaker in the building's electrical cabinet
before performing the measurement.
» First measurement on the primary side of the
charging system
On the primary side of the charging system,
measure the insulation resistance at the
connection point of the charging system's
supply cable in the building's electrical cabinet.
The value must not be less than 1 MΩ.
The Wallbox is equipped with an over-
i
voltage protection device. This may be
taken into account when performing the
measurement.
» Second measurement on the secondary side of
the charging system
To do this, connect the charging coupler to a
test adapter for vehicle simulation according
to EN 61851-1. Perform the insulation meas-
urement via the measuring sockets on the
test adapter. The value must not be less than
