If you can tell me how, that would be a great help, as I am a bit afraid to connect these unless I know for sure?
Thanks.
Brian,
I am not familiar with this particular control panel but the following are more or less generic instructions.
Neutral should be connected to the contact that also connects to contacts 3, 8 and 11 (sometimes it is easy to find out just by looking the copper paths on the back side of the control board - failing that, use the continuity check function of a multimeter).
Keep in mind that the control board will work regardless of the way you connect phase and neutral on contacts 1 & 2. However, for safety reasons (control board relays should control the phase, in the same way switches are wired to control the phase, so that, when not activated, danger of electric shock is minimized) proper connection is important. You are absolutely right in wanting to sort this out.
The manual suggests that this particular control board is not connected to ground. That means you only have to connect ground straight to the grounding wire(s) of the operator(s).
