I sent the first unit back because it simply wasn't working. The seller replaced the unit and, having wired it in, this one isn't doing anything either. Now I'm thinking: what am I doing wrong??
I installed a dedicated double pole 20amp breaker installed across both phases. Ran 14AWG 3-wire (red/black/white) from the service panel to a metal gang box next to the service panel. Attached the white wire to the neutral buss bar, the red wire one breaker connection and the black wire to the other breaker connection. Then took the leads from the XPCR as follows: white to white, red to red, black to black. Capped off the fourth wire, which is another black for 3 phase installation.
Switched the breaker on and, nothing. The CM15A is plugged in on the A phase and modules on that side continue to work. Modules on the B phase will not respond (though they will if I plug the Signalinc dryer coupler back in.) There is no LED activity on the XPCR. I tested the leads at the gang box and am getting 220 there.
Either I've done something wrong, or I received a (second) bad XPCR.
Does anyone have any insight, and is there any way to test the XPCR? I'm at a loss.
Thanks!
