Connecting power

3.1 Power source

There are different options for the power supply:
• The 24 V DC ship supply provides power for the terminal.
• A 12 V DC supply provides power for the terminal. Note that the maximum
allowed source impedance is much lower for a 12 V DC supply than for a
24 V DC supply. Also, the total output power available for PoE is limited
when the power supply is 12 V DC.
• A 230 V AC supply provides power through an AC/DC power supply.
Be aware of high start-up peak current: 20 A at 24 V, 5 ms.
The terminal is equipped with an internal 20 A Fuse, so no external fuse is
necessary in order to protect the terminal. However, in order to avoid short
circuit in the power cable/connector, the ship's DC outlet should be protected
by a 30 A fuse or circuit breaker.
