*1: This noise filter is for FCN-500 power supply line. Refer to “Table Example Noise filte for FCN-500 Power line”.
*2: This noise filter is for external power supply unit. Regarding necessity of the noise filter, follow directions on instructions for
marine standards of this external power supply unit.
*3: If the noise filter for the external power supply unit is equivalent to the one of “Table Example Noise filter for FCN-500 Power line”,
both noise filters can be shared.
Figure Wiring for power cables
IMPORTANT
Lay the incoming wires to a noise filter separately from its outgoing wires.
Minimize the wiring to the ground terminals of the noise filters to minimize the impedance.
