In which orientation do I mount the IC chips on K1_1 and K1_2? There is no identifying markings on the two ICs to tell me how to orient them.
Thanks.

There is an elongated "dot" on the relay that indicates pin one:  The silk screen on the circuit board has a notch (near the edge of the board). This is the indicator of the Pin 1 end.

Do you mean the black line? There is a physical notch in the middle of the 4 pins. I also looked it up in the omron data sheet, but I did not find it very useful.
Thanks.

The elongated dot - got it. Did not see that part when I responded.
Just wanted to make sure before I soldered the parts onto the board.
