Documentation related to installation of the EMS equipment type into the traction unit type:
e) installation specification taking into account device environmental, safety, performance and installation constraints;
f) installation design and settings according to installation specification;
g) installation procedures:
h) installation requirements and constraints to ensure compatibility between the traction unit type and the EMS equipment type:
i) Installation design measures to provide protection froni non-authorized access.
5.4.2 EMS installation design review assessment
5.4.2.1 General
Using the documentation listed above and, if necessary, any further information provided by agreement with the installer, the EMS installation design review is carried out and shall verify that the EMS equipment type and the traction unit type are compatible (e.g. mechanical, temperature, electromagnetic compatibility, clearance, rated insulation, safety, and maximum cable impedance 1 lengths, etc.).
5.4.2.2 Insulation
Check the insulation level of the EMS equipment type installed on board the traction unit type is in accordance with the requirements of EN 50463-1:2017, 4.3.8.1. Documentation shall be provided which details the insulation level and overvoltage ciass and shows that the requirements are fulfilled.
Check that any installation constraints and requirements. which are relevant to the installation testing activities, are clearly documented.
5.4.2.3 Enclosure
If additional enclosures are provided as part of the installation design, check that they are in accordance with
EN 50463-1:2017, 4.3.7.2.
5.4.2.4 Protection from non-authorized access
Check that all requests for access to data, software or system parameters relevant for the production and storage of CEBD go through an authorization procedure before access is granted and that all requests and all changes are logged.
Check that any measures for protection from non-authorized access necessary at the installation routine test are clearly documented.
The review should focus on checking (i) the adequacy of the protection afforded by device level measures when integrated into the IUA, and (ii) the adequacy of any additional measures (implemented by the integrator or the installer).
5.4.2.5 General safety requirements
Check that the EMS design meets the safety requirements in accordance with EN 50463-1:2017, 4.2.6.4.
Check that any measures related to the general safety requirements, which are relevant to the installation testing activities, are clearly documented.
5.4.3 Installation Design Review Report (SDRR)
In case of a positive fulfilment of all the requirements of 5.4 the assessor shall issue an Installation Design Review Report. The Installation Design Review Report shall be included in the Conformity Assessment File.
5.5 EMS Installation type test
5.5.1 General
The EMS installation type test snaIl be performed on an EMS of a specific equipment type installea on a traction unit of a specific type.
5.5.2 Installation procedure
The installer shall produce all the documentations necessary to install the EMS equipment type within the specimen of the traction unit type in accordance with the installation design taking into account the limitations imposed by the traction unit (e.g. significant sources of electrical and electromagnetic disturbance, cable routing constraints. etc). The installation procedure shall be included in the Conformity Assessment File.
5.5.3 Installation type test procedure
The installer shall prnduce a type test procedure for the EMS equipment type which describes how the type tests are to be performed. The procedure shall also take into account requirements not verified durin9 installation design review and shall clearly identify the service, operational and test interfaces including arrangements for applying test signals and monitoring performance. This document can be produced in collaboration with the test authority. The installation type test procedure shall be included in the Conformity Assessment File.
5.5.4 InstallatIon type tests
5.5.4.1 General
As a minimum the following test activities shall be performed.
5.5.4.2 Visual Inspection
Check that the IUA matches the EMS equipment type and traction unit type specified into the installation design, Carry out a visual inspection in accordance with EN 50155:2017, 13.4.1.
Check If EMS equipment type has been Installed In accordance with the installation design and installation procedures.
Check if the status of the required indicators can be ascertained,
5.5.4.3 EMS data flow test
Provide a known input quantity to the EMS. deck that the data are stored correctly in the DHS and is consistent with the input signals applied. Simulate data export from the OHS via the local service port and compare the data stored in the DHS with data exported and ensure the data exported is identical to that held in the OHS.EN 50463-5-2017 pdf download.
