8 Power-up
The power switch is located next to the 100-240V~ [10] mains inlet.
If using an external DC power supply unit connected to 24V DC IN [9], the
console can be switched on and off with the PSU’s power switch.
For battery operation an external switch must be connected in series with the
supply cable. Please note that for battery operation, an external, UL approved
fuse (T 5 A H 250 V UL/CSA) must be connected in series with one of the
supply lines as well.
After switching on, the console performs a self-test routine, starts the operat-
ing software and loads the initial snapshot.
