1.3 Notes for people with a pacemaker (PM) or implantable cardioverter defibrillator (ICD)
Charging systems from Heidelberg that are operated as intended, comply with the European guideline on
electromagnetic compatibility regarding radiated interference.
Should people with a pacemaker (PM) or implantable cardioverter defibrillator (ICD) wish to conduct activities on
charging systems and their devices in the intended manner, Heidelberg is not in a position to make any statement
regarding the suitability of such medial devices. Heidelberg is not able to assess the pacemakers or concerned
implantable cardioverter defibrillators with regard to their susceptibility to electromagnetic radiation. This is
something that only the manufacturers of the pacemaker or implantable cardioverter defibrillator can do.
Heidelberg therefore recommends only allowing the people in question to work on its charging systems after
consultation with the manufacturer of the pacemaker/defibrillator and the relevant insurance company. Ensure at all
times that no health or safety risks are involved.
NOTE: PEOPLE WITH A PACEMAKER OR DEFIBRILLATOR MAY NOT WORK ON OR STAND NEAR THE CHARGING SYSTEMS AND
THEIR DEVICES, E.G. TO PERFORM MAINTENANCE OPERATIONS OR RECTIFY ANY FAULTS.
1.4 Replacement
of charging cable without hazards
Before replacing the charging cable:
•
Deenergize the charging system.
•
Secure the charging system against being switched on.
•
Check the absence of voltage.
•
Ground and short-circuit the cables, e.g. in the building sub-distributor.
•
Block off or cover the neighboring live parts.
•
Returning to operation is carried out in reverse order.
•
Check the entire charging system before turning it over to the customer
During the charging process (testing):
•
Keep unauthorized persons away from the charging system.
•
When the charging system is connected, you must not clean or wash the vehicle with a highpressure cleaner because the
plug-in connection is not sealed against pressurized 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. Leave a
sign with the name of the person authorized to switch on the circuit breaker.
•
Call in a qualified electrician immediately.
Electrical devices:
•
The housing of the charging system must always be closed.
1.5 Installation and tests
Information on testing after cable replacement
Test the charging system after replacing the charging cable in accordance with national regulations, e.g. EN50678 "General
procedure for verifying the effectiveness of the protective measures of electrical equipment after repair" and EN 50110-1 and EN
50110-2 "Operation of electrical installation".
•
Cable protection/Residual current protection
Check whether the cable protection has been carried out in accordance with the operating manual of the charging system.
Information on initial inspections after installation and repeat inspections National regulations may stipulate inspections of
the charging system before start-up, after repair and at regular intervals. Perform these inspections in accordance with the
respective rules and regulations. Information is given below on how these inspections can be performed
.
•
PE conductor test
After the installation and before switching on for the first time, test the continuity of the PE conductor. For this, connect the
charging coupler to a test adapter for vehicle simulation in accordance with EN 61851-1. Measure the
resistance of the PE conductor between the PE conductor socket of the adapter and the connection point of the
PE conductor in the building's electrical cabinet. The value of the PE conductor for a total conductor length
(connecting line to the charging system and the vehicle charging cab
le) of up to 5 m must not exceed 300 mΩ.
For longer cables, the value can be increased in accordance with the applicable national regulations. In any
case, the resistance must not exceed a value of 1 Ω.
•
Insulation test
Two insulation measurements are required because the charging system is equipped with a disconnecting relay. The
charging system must be disconnected from the power supply for this. Therefore, before the measurement, switch off the
supply voltage using the circuit breaker in the building's electrical cabinet.
o
Measurement of primary side of charging system
Measure the insulation resistance on the primary side of the charging system at the connection point of the power
supply line to the charging system in the building's electrical
cabinet. The value must not exceed 1 MΩ.
The Wallbox has a surge protector. This may be considered in the course of making measurements.
o
Measurement of secondary side of charging syste
For this, connect the charging coupler to a test adapter for vehicle simulation in accordance with EN 61851-1. Measure
the insulation via the measuring sockets on the test adapter. The value must not exceed 1 MΩ
Alternatively, the differential current method can be used in conjunction with measurement of the PE conductor current.
In both cases, the value must not exceed 3.5 mA.
For these measurements, connect the charging coupler to a test adapter for vehicle simulation in accordance with EN
61851-1. The measurements must be carried out with the adapter in the C mode. Measure the differential current at the
connection point of the power supply line to the charging system in the building's electrical cabinet.
•
Test of the power-off condition in case of a shortcircuit (Z
L-N
)
For these measurements, connect the charging coupler to a test adapter for vehicle simulation in accordance with EN
61851-1. The measurements must be carried out with the adapter in the C mode. Carry out the measurements on the
measuring sockets of the test adapter. The values must comply with those of the selected circuit breaker.
•
Test of power-off condition in case of a fault (Z
L-PE
)
For these measurements, connect the charging coupler to a test adapter for vehicle simulation in accordance with EN
61851-1. The measurements must be carried out with the adapter in the C mode. Carry out the measurements on the
measuring sockets of the test adapter with a suitable instrument. The values must comply with those of the selected circuit
breaker.
•
Test of the integrated DC residual-current detection
For these measurements, connect the charging coupler to a test adapter for vehicle simulation in accordance with EN
61851-1. The measurements must be carried out with the adapter in the C mode. Carry out the measurements on the
measuring sockets of the test adapter with a suitable instrument. If the residual current is greater than 6 mA DC, the
charging system must disconnect the charging coupler from the power supply. The fault indicator on the charging system
must be activated
.
•
Test of the upstream RCD
The upstream RCD has to be checked at the connection point of the charging system supply in the building's electrical
cabinet. The RCD must trip in accordance with the national regulations
.
1.6
Protective
devices (Fig.1)
Protective devices (using example of Heidelberg Wallbox Home Eco) are the following components:
1. Housing, 2.Charging cable, 3 Protecting cover, 4 Charging coupler
Checking the protective devices
Following the replacement, conduct a visual inspection of the protective devices for damage in accordance with the
applicable operating manual of the device on which the replacement was carried out.
Have a qualified electrician carry out electrical function tests in accordance with the national regulations
1.7
