4.3.2 DC Power Cable
You can supply DC power to the BDU in the following methods depending on the power supply available in
the vessel. Intellian provides a DC Power Cable, an AC-DC Adapter (optional), and a Terminal Block for the
power connections.
1. Connecting to Battery (default): Using the DC power cable (1 m), supply the DC power to the BDU from
the battery. The power cable is installed with the Molex connector (P/No. 1716920204, Max. AWG 12).
Use 1~2 m (3.28~6.56 ft) length wire for the power supply to prevent voltage drop. If you need a power
cable longer than 2 m (6.56 ft) refer to the following table.
2. Connecting to AC Power Source (optional): Using the AC-DC adapter (110~220V Input, 24 V DC output)
and power cord, supply the DC power to the BDU from the AC power source. (You can nd the AC-DC
adapter in the 19-inch Rack Mount Kit).
