Direction of terminal blocks in PCB layout
You need to look at the terminal block datasheet. You want to pick the terminal block and use a footprint that fits the terminal block, not pick some random footprint out of the library and try to find a terminal block that matches it. 

For example: 



From the drawing you can easily see that the wires enter from the 'bottom' of the recommended hole layout. 

It would also be normal to label the terminal block from left to right, looking into the wire entry holes. 

Make sure the hole sizes are appropriate (number one cause of disappointment with through-hole boards) and you can probably increase the size of the pads to make it more robust.
