VCM100 power wire gauge
You must provide suitable power wires to connect the VCM100 to the vessel's DC distribution panel or battery isolator switch.

It is essential that both power cores and the screen (drain) are connected and that the connection is of very low resistance, as considerable power passes through this connection.
The following table provides recommended total power cable lengths and gauges. These figures relate to the maximum round-trip length of power cables from the vessel's DC distribution panel or battery isolator switch to the VCM100. Exceeding these lengths may cause unreliable operation.

If the required lengths result in unacceptably large diameter cables, use 2 or more smaller gauge wires to achieve the required copper wire cross-section. For example, using 2 pairs of 2 mm2 cables is equivalent to using 2 single 4 mm2 cables.
