Oh yes. That sounds like a mains filter unit. Inside
there are several
capacitors and inductors. If you're very lucky there'll be a schematic
printed on the can somewhere.
I'm not lucky :) All there is is a part number and legends telling me which
is the line side and which is the load side.
before? The
thing's got to be 4 or 5 inches by 2.5 inches so whatever goes
on in there is anyone's guess. If I was at work I may be tempted to unhook
the earth wire that's bolted to the chassis but it's there for a
reason....though normally I'd expect that to be there to ensure the psu
casing was never live.
IOt may not do you any good to do that. Often the can is connected to the
mains earth anyway, the wire is just there for a 'belt and braces' aproach.
What I would do as a temporary measure is to remove
that filter can
altoghter and wire a mains cable (or IEC plug) with earth to the PSU
chassis and live/neutral to the 2 spade terminals (this leaves the
breaker in-circuit, right? I don't have a Pro in front of me at the
moment, I can dig one out if need be). See if the machine still trips the
mains.
I'll cut up an IEC wire over the weekend and bypass it with fingers most
definitely crossed.
