* Note
1. Not suitable for bistable relay with two coils.
2. For a 16A 1 pole relay the following jumpers have to be connected;
11 to 21, 12 to 22 and 14 to 24.
3. Insertion of the relay.
First the ejector (and eventually the module) has to be mounted onto the
socket. Then the relay has to be set in the correct position and pressed
into the socket until the ejector snaps over the top of the relay.
