R76 wiring connection for 230/460 SEW Eurodrive
motors This is a DRS motor though this will
apply to all DR series motors, DRE's, DRN's,
and DRS's.
This is your terminal block, stator only for
demonstration purposes.
You've got your nine wires here, and jumpers.
Got your R76 connection diagram sticker, should
come on the inside of your conduit box lid
(this is just a random one I found in the
trash, that's why it's blue).
This is the R76 paper wiring diagram version,
should also come inside the conduit box, which
shows you why you should never move the yellow,
brown, and white wires on either side of the
terminal block.
It's because due to the way the motor is wound,
if you move those wires around and lose track
of them you will short circuit the motor if
you wire them back incorrectly.
You can specify at the time of ordering, how
to receive the motor: prewired for either
230 or 460.
As you can see by the wiring diagram this
has been prewired for 460.
You've got your blue, black, and red wires
on W2, U2, and V2 respectively.
As you can see here on the terminal block,
terminals -- posts, are labeled.
So you got W1, V1, U1, on the top over here,
and V2, U2, and W2 on the bottom here.
Now top and bottom are respective, if the
motor was flipped around [right] your terminal
block would be the other way around, and then
this diagram would directly apply 1:1, right?
But you can mount your motor in any direction
possible, and the terminal block post position
will change so pay attention to what the terminals
are labelled and not how they are oriented.
So, if you want to change the motor from,
currently, 460 to 230, you can see the wiring
diagram it tells you to only move the blue,
black, and red wires and to apply the jumpers.
So, to do that I'm going to jump ahead here
and just remove the jumpers, and the colored
wires.
Okay, we're back and you can see that I've
wired it for 230 now, swapped it over from
460, so I've got my blue on terminal W1, you
can read it right there, red on V1, and black
on U1.
Then you've got the jumpers jumping, which
you can't see now, but those terminals are
the W2, V2, and U2 terminals.
Just follow the wiring diagram, and you can't
go wrong.
Terminals are called out, wire colors are
shown, and the jumpers are shown.
So if you're jumping from 230 to 460 remove
the jumpers, move the wires (the black, red,
and blue wires) from the U1, V1, W1 terminals
over to W2, U2, V2 and if you're moving from
460 to 230 do the reverse.
Put the jumpers on, move the wires down.
That's it.
And there you have it.
