the cabinet, before performing any installation, disassembly, repair
or replacement of components.
2. Do a voltage check and make sure that the electrical power is
disconnected from the system.

450 kW E-Bus Charger.
4. When the system is in an open or dangerous condition, do not allow
unqualified persons to go near it. Instruct and warn people about the
potential harmful high voltages.
5. The installation and maintenance personnel must supply their own
lighting equipment, since the HVC 450 kW E-Bus Charger has no
lights inside the cabinet.
6. Always connect the Protective Earth (GND or PE) first, before
connecting the neutral (N) and Phase (P) wiring.
7. Correctly lock the door after installation or service operations.
Make sure that there is a minimum free space of 39.37 Inch in front of
the door of the Power Cabinet. The minimum space is necessary to allow
