Wiring Huanyang HY02D223B

**Stan** · 01-01-2017

Hi, I've recently bought Huanyang HY02D223B and I'm stuck with wiring.
I've read 67 pages manual and could not find single sentence where I should conect L (live ) N ( neutral) and earth.
On manual say it is single phase 230v wired or 3 phase 380v wired.
If my house have 380 V supply I have no problem with wiring.
But my house is single phase 230v.

All I need is someone to tell me where to connect
L as ( live)
N as ( neutral)
Earth.
Many thanks. Stan

On page 10 of the manual, the connections R,S,T are for three phase, but you just use any two of them to connect Live and Neutral of single phase. Earth in both cases goes to the E terminal.

Hi,
Thanks for replying,
yes you are correct what comes to maual and wiring, all is there.
But real life is different.
L goes to R or S or T
Earth goes to E(9)
And N?
I can't connect N to R or S or T
R,S,T is phase not Neutral
It tripped my Fuse straight, I've tried, twice.
Thanks for replying. Stan

Cropwell is quite right - you connect live to one of the RST terminals and neutral to one of the other two. It doesn't matter which. My HY inverter has been working beautifully for a few years like this, just like many others. If your MCB or RCD is tripping, there must be a fault elsewhere - can you describe a bit more what the inverter is plugged in to?

Neale and Rob of are correct but there has been a post on the forum that some VFDs have a problem with this (and I can't remember) but I think it is something to do with an internal EMC filter that can be disconnected to stop this.

This might have been the post http://www.mycncuk.com/threads/6593-...ghlight=filter #6

Are you connecting to a dedicated MCB ? I know when I first started using (any) inverters in my garage they would "always" trip the main house supply. I got my sparky mate round and he said "yeah, it will always pop the fuse unless you fit a (can't remember what he said) ???? Anyway, he done his thing and fitted a dedicated socket in the garage which I now run all my VFD's from, problem solved. Just to add, if I plug a VFD into any of the other normal sockets, they instantly trip the main supply in the house.
