I wired up this Sherndian MP-09 magnetic switch today, but I can't get it working. It's a 3-phase 240 V switch.

When I press the green button, nothing happens. When I take the cover off and press the manual contactor override (my screwdriver is pointing at it) the switch works.
When I press the on switch with the cover off, nothing.

I bought this switch last year, but am using it now for the first time, and I bought a second one recently for another machine. I wired the second one up and I also failed to get it working.
It's a pretty popular switch as far as I can see, so I'm hoping someone can tell me what I'm doing wrong.
Thanks, Mark
