Chapter 3: Connecting power

3.2 Power cable selection

3.2.1 Source impedance
The length of the power cable depends on the type of cable used and the
source impedance of the DC power installation in the ship.
The maximum allowed source impedance depends on the utilization of the
power range of the terminal DC input (10.5 - 32 V DC; 14 - 5.5 A).
Select a power outlet from the DC system and measure the source impedance
of the ship installation as described in Measuring the ship source impedance
on page 118 in Appendix B.
Note
If the total source impedance is higher than the limits stated in this
section, the terminal may start to on/off oscillate.
For further recommendations on power cable selection, see the next section.
