can't believe DELNO takes that much current, so most filters will
Coincidentally I have a Schaffner FN9222R sitting here.
It has a diagram on the case and it says "250V 10A @ 50degC".
If a properly-funcitoning DELNI draws anyhting like 10A from the mains, I
will eat one :-). I am sure it would be fine.
I am absolutely sure it will be fine in this respect.
So I'd be surprised if that didn't work quite nicely in a DELNI. I
don't have a DELNI to hand so I cannot check whether it would be a
good physical fit.
I do have the DELNI technical manual (and I've scanned it so it should
be on the net) and figure 5-2 suggests that it's connected via the
usual spade connectors. So if it fits in the cut-out then it should be
And if it isn';t, a file will take care of the problem :-)
Hmm... I definitely don't want to do that. From the pictures on the
Schaffner site it *looks* like it will fit the cutout just fine. I'd like to
measure the old one, but I can't get the damn thing out at the moment. One
of the nuts holding it in is in an awkward position, annoyingly, I don't
have the 1/4" spanner you need to undo the nut and pliers won't reach. I am
going to have to find a suitable spanner first.
As for the wiring, the ground (earth) lead will go to a tag that it

The other2 tags ar, of
course, live (hot) nd neutral. It probably doens't matter which way round
conenct them, but in every similar mains filter
I've used, the output tags
directly behind the corresponding plug pins, so
it's easy to work out
live and which is neutral. They may even be marked o
nthe filter can.
Yes it has an earth tag and two other tags. There are markings on the casing
but I can't see them properly until I can get the thing out. I have closed
it up again to avoid losing bits and pieces so can't check wire colours.
When I get the necessary spanner and replacement module then I will open it
up again and check against the colours you suggest below.
I don;t know what wiring colourse are used in the DELNI. It's likely to be
Black : Live
White : Neutral
Green : Earth
Brown : Live
Blue : Neutral
Green/Yellow : Earth.
