Hi Guys,

Trying to replace a failing Schaffner inlet filter (Fn-376- single fused,voltage selector) with a brand new Delta (03sb4- double fused,voltage selector) and can use some input on how to correctly wire things to the new filter, as they are slightly different. I will be using it on 240V primarily, but would like to maintain compatibility to the 110-120V if needed.
I've attached some pictures and a drawing of the old and new inlet filter.
Thanks a lot for your input.

Comparing the left side of the old vs new you have
N
PE
P
and
L
N
G

The mains connects to Neutral, ProtectiveEarth and Pole? and these translate to Neutral, Ground and Live

On the right hand side of old you have M, Earth symbol and L These
will translate to the new as B, earth symbol and D
These three connections will feed into the F, D & B of the old 115/230Vac switch.

You just use the same THREE connections at each end of the filter.

And use a Mains Bulb Tester to power ON. This will allow you to check your wiring without blowing up your equipment.
