*1:
This noise filter is for the power line of SPW48
, S2PW50
, and FAN. Refer to "Table Example of a noise filter for the power line
of SPW48
, S2PW50
, and FAN.".
*2:
This noise filter is for the external power supply unit. Regarding necessity of the noise filter, please 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 ones of "Table Example of a noise filter for the power line of
SPW48
, S2PW50
, and FAN.", both noise filters can be shared.
The following table shows example of a noise filter.
