Remember to upgrade the cable if it runs in thermal insulation in a loft, or for a longer distance.

2.A means for disconnection in all poles must be incorporated in the fixed wiring in accordance with the wiring rules.

We recommend a ceiling switch mounted in a convenient position.

3.Cut back cable as in diagram 7. Connect cable to terminal block making sure that all the retaining screws are VERY TIGHT and that no cable insulation is trapped under the screws.

WARNING: FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD RESULT IN FAILURE OF THE TERMINAL BLOCK

4. Re-Fit the corner section back into the backplate.
