infrastructure in fully operational state before
delivery and installation of the devices and bears the
responsibility for these systems and interfaces to be
connected:
- Power supply (energy supply company ESC)
- Wastewater drainage for defrosting water
(condensation water connection)
- Overall market control
- DFU access for remote maintenance (optional)
For technical data for interfaces, see → 2.2.
Technical modifications to the device can only occur
with the coordination and approval of the
manufacturer.
