2.3 Power Supply

The power supply of the Java Box Terminal has to be a single voltage source of POWER 6V-30V

capable of providing a peak during an active transmission. The Java Box Terminal is protected from

supply reversal voltage. An internal fuse ensures an electrical safety according to EN60950. This fuse

is not removable. A fast acting fuse 0.8A with melting is necessary to use with the Java Box Terminal

at a 24V power supply system for vehicles. The power supply must be compliant with the EN60950

guidelines.
