4.7 Ground Potential
The shields of all interface connectors are grounded to the chassis. The user then has the option to ground the system
with a ground wire.

4.8 Power On/Off Switch
The power switch is clearly identified and located on the front panel. [MIL-STD-545M]
The power on/off switch does
not
cut all electricity to the system. In the "off" position, a microcontroller is still
working, to supervise wakeup events (switch, Wake on LAN). [MIL STD 454M] In this state, the system is consuming
approximately 300mW.
To turn on the system, the power switch must be pressed for at least one second. While running, the system can be
forced to shut off by pressing the on/off switch for 4 seconds.
To completely power off the system, all power must be disconnected from the device by either removing the cords
from the device or from the power sources. All connectors must always be easily accessible.
Be sure to disconnect the power supply before opening the system.
4.9 Safety: Batteries inside the Device
Caution: Electric Shock!
The system has an integrated backup lithium battery (RTC). The battery compartment is not vented. The system casing
protects the operator from a possible exploding battery cell.
The lithium battery can only be replaced by the manufacturer!
If anyone other than the manufacturer changes the lithium battery, there is the danger of an
explosion ! The replacement lithium battery must be UL approved.
Lithium batteries cannot simply be thrown away as domestic waste. Local regulations concerning the
disposal of hazardous waste materials must be followed (e.g., by taking to specially designated
collection areas).
