The following is directly from the operating sheet included with the valve...


"Electrical Connection
Slide gray connector from black housing (can be pushed out from top with supplied screw), and wire per the following:
1 – Negative
2 – Positive
3 – Not required
Note: If the polarity is switched, the valve will still switch, but the LED will not work."

A copy of the operating sheet will be on the FESTO.COM/US website within the next day.
