*1: This noise lter is for the power line of SPW48, S2PW50, and FAN. Refer to "Table Example of a noise lter for the power line
of SPW48, S2PW50, and FAN.".
*2: This noise lter is for the external power supply unit. Regarding necessity of the noise lter, please follow directions on
instructions for marine standards of this external power supply unit.
*3: If the noise lter for the external power supply unit is equivalent to the ones of "Table Example of a noise lter for the power line of
SPW48, S2PW50, and FAN.", both noise lters can be shared.
The following table shows example of a noise lter.

IMPORTANT
Lay the incoming wires to a noise lter separately from its outgoing wires.
Minimize the wiring to the ground terminals of the noise lters to minimize the impedance.
