I have a 3-phase blower motor that I am looking to control from a Danfoss VLT 2800 that I purchased on eBay.
I have in the shop a receptacle that looks like this:
If I put a meter from neutral (horizontal middle) to either hot side (the verticals) I get 120v. Across the hots I get 240v. The table suggests that for single phase I should only be connecting two wires, including a neutral. But with the neutral I have I only get the 120v. Should I just be connecting the two hots?
For reference, our building has high-leg delta service.
European phase voltage is 230 Vrms (line voltage is therefore 400 Vrms). Here in the US we have to connect the two "hots" to get a comparable voltage, that is 240 Vrms.
You are fine connecting one split-phase "hot" to L1 and the other one to L2. Make sure to connect the ground as well. The split-phase neutral should be left disconnected.
Yes, two hots. And most important is the ground, leave the neutral unconnected. By the way what's "high-leg delta service", and the table you are refering at is not visible. Also you have to check the motor connection star/delta for correct voltage.
