Power cable recommendations
Overview
The terminal is delivered with a power cable, which can be extended according to the
recommendations in this section.
• When extending the power cable, positive and negative supply wires must be installed
closely together side by side to keep cable inductance low.
• Ensure that cable inductance for the selected cable at the desired length is below the
50 H requirement.
The power cable contains the following wires:
Calculating the maximum power cable extension
For 24 V DC operation, the total impedance must be max. 500 mOhm, including the source
impedance in the ship installation.
For 12 V DC operation, the total impedance must be max. 85 mOhm, including the source
impedance in the ship installation.
The total impedance is made up of the following:
• the source impedance in the ship installation
• the cable impedance of the supplied power cable, including the impedance in the joint of
the two cables. In the following example, the impedance of the cable and joint is set to
10 mOhm (1 m power cable). Note that if the cable length or type is changed, the
impedance will change accordingly.
• the extension cable impedance.
