in manual it describes how to wire it for 3 phase or single phase
have need to bring a certified electrician since i europe it 240 neutral - phase and
in america and canada it 240 volt phase to phase (phase - neutral was 120V)
if you what to see inside of the reflow .. http://www.alphatronique.com/IMG_6121.JPGhttp://www.alphatronique.com/IMG_6122.JPGhttp://www.alphatronique.com/IMG_6123.JPGhttp://www.alphatronique.com/IMG_6124.JPGhttp://www.alphatronique.com/IMG_6125.JPG
you see for single phase all 3 phase was short together ...
as for the 2 side trick i use "335-1093-ND" whit "1548CK-ND"
since i put 3mm border to pcb for hold it on pick place i just broke the corner
and fit screw on it ,rubber build in the screw head hold it even if only slightly tight by hand
that work great and fit my need since i not do any big panel i prefer do board to board
and that fit also my low volume niche market that come not penalised 99% of the time..
p.s. ok seem that i seriously upgrade it control board my was plain RS-232 whit a z80 cpu
and almost graphic monochrome LCD ,but now it touch screen whit usb
