Hi Ken...

depends on what voltage you are running to the variac as to how it will 
be wired up....

if you are using 120VAC  ( 120 in 140 out) , wire as follows ...

hot wire into #2 screw, controlled hot wire out of # 3screw to load. 
Neutral into #1 screw , neutral out of # 1 screw into load.


for 240 VAC

hot #1 ( one phase of 240)  into #1 screw, hot #1 out of screw #1 to 
load,  hot #2 ( other phase) into # 2 screw, controlled hot #2 ( other 
phase ) exits #3 screw to load.




and if that doesnt help see this link....
