5.1. Opening and Closing the Chassis
The KBox F-420-WLU is factory configured to meet customer requirements. Kontron
does not recommend opening the system as this may cause damage to internal
components.
Before opening the KBox F-420-WLU, the system must be switched off and disconnected
from the main power supply. Also, disconnect all peripheral devices from the KBox F-
420-WLU. Before you begin, ensure that you have a clean, flat and ESD-safe surface to
work on.
For opening and closing the KBox F-420-WLU, please perform the following steps:
1. Close all applications. Shut down the system properly and disconnect the connection to the main power source.
Disconnect all peripherals.
