EMC-HW50C install

[Gardner Yeaw]

I installed the EMC-HW50C today in my 1978 FC and uploaded some
pictures to the Wanderlodge forum (the other one) titled "EMC-HW50C"

I chose to install it under the dinette seat behind the transfer
switch because it emits an audable 'hum' and I didn't want it near
the main sleeping area.

I mounted it on a peice of plywood that is cut to fit behind the
transfer switch and to be screwed to the seat brace and floor. I
mounted the device at an angle to allow room for the in and out
heavy guage wires.

I also left enough length on the wires to allow me to make the
connections with the device lifted up and afterward mount the board
with the device and wires attached. It is not easy to get those
heavy guage wires on the output side through the current sensors and
into the connectors. If you mount the device in a hard to get at
place and then try to wire it up, you will discover many new ways of
concatinating four letter words.

One other thing to think about is connecting the remote cable
while the cover is off the device. The circuit card that it plugs
into can move a little and make it tough to get the connector
inserted. In my installation the connector is not directly visable
and so I pluged in the cable while I could still move the card if
needed, and then installed the cover.

It works as advertised. I was too far from the power connection
for my 30 amp cord, so I plugged into a a 20 amp outlet with a long
extention cord to test. Well, it shut off right away with a low
voltage message. I discovered one of the under cabnet heaters was
turning on and that was too much for the small guage wire.

The second test was with a solid 30 amp connection. That worked
fine and read out the voltage and current as expected.

The third test was the generator. Sixty one Hz, 130 volts on one
leg, 125 volts on the other. Looks like I need to figure out how to
adjust the voltage on the Onan 6.5. I don't know if there is a way
since it is a 1978 unit. I had to replace a burned wire once, and I
never saw a regulator anywhere.
