No, the data sheet isn't very specific about how it works. But it appears from this data sheet, that you energize one coil to "latch" the relay on, and enrgize the other coil to release it. Or you can reverse the polarity on a coil to reverse its effect (e.g., one polarity to latch, and reverse polarity to release.

At the bottom of pg 4, right hand most of the 3 diagrams, (where it says
"Contacts in reset position. Both coils can be used either as set or reset coils.". I think that bit applies to your relays. You can either energize one coil to "set" the relay and the other coil to "release"..., or you can use one coil and hit it with one polarity to "set", and reverse polarity to release".
