There doesn’t appear to be enough information here to do anything with. There is no indication in the supplied data of what the various screw terminals do. Presumably the two sets of three are the switched set Input to Output. The coil must be somewhere on the other terminals but it is unclear where as there are 8 terminals with no information on what any of them do. You appear to want this one. I assume the two pairs circled in blue are the three phase connections, presumably one in and one out (although which is which is not documented) and some set of the other four pairs are the coil or coils. This is the only connection information that I see in the data sheet and it has no indication of how it relates to the screw terminals. The labels on the device are also unreadable in either your image or the data sheet.

I assume we want the bottom one but it is not at all illuminating as there are 4 possibilities for the coil shown as there are 4 connector pairs available.

We can exclude the 2 possibilities on the right as these are labelled NC (normally closed) and NO (normally open).

The 2 connectors on the top seem labelled A1 and A2.

There is a snubber/DIAC unit available (surge unit, pg54) which appears to be connected to A1 and A2.

Also there are replacement coils available (pg56), which come with the terminals A1+A2

This leaves us with both pairs of A1/A2 being connected to the coil,
L1-U & L2-V & L3-W & 43-44 => NO
31-32 => NC

I would rather have proper information than make a guess which may be wrong. I’ll choose to wait for proper information.

No indication where A1 and A2 are connected (or if they are unused) or what the other connections are for. We need a diagram which shows all the connections and what they do which so far isn’t here.
