.. _Electronic High Voltage Junction Box:

High Voltage Junction Box
~~~~~~~~~~~~~~~~~~~~~~~~~
.. ToDo: Schöne Einleitung fehlt noch

The high voltage junction box contains the following electronic subsystems: 

- :ref:`Electronic Management System Master`
- Isolation Monitor Device (IMD)
- :ref:`Electronic Accumulator Indicator Light`
- Main Fuse
- Accumulator Isolation Relays (AIRs)
- Current sensor

The schematic for the high voltage junction box is available in the following git repository:
`Junction Box <https://gitlab.fs-europe.eu/fs-europe-references/fseu-reference-accumulator/-/tree/main/HW/Overview_HV_Box?ref_type=heads>`_

The following components are suggested for the reference design usage:
