the wires are in correct terminals and the connections are tight. 
3-2-4. 
 Before connecting AC output and AC input terminals of the ST series, 
you can either use front compartment cover or a side hole to coil out. 
Both AC input and AC output are coiled out from the front compartment 
cover when in production. If you want to change the position, you 
should open the top cover first, and then switch the wire of the front 
compartment cover and the plastic cover of the side of top cover.
