1. Position the cable clamp and fixing (not supplied) onto the support structure | 2. Install LV MV HV cable | 3. Locate the other half of the cable clamp. Secure with a nut and washer (not supplied) to the support structure and tighten the cable cleat | 4. IMPORTANT: Do not over tighten the cleat. The cleat should secure the cable but does not need to be so tight that the cable bulges at either side of the cleat |
WARNING – to prevent eddy currents and heating of the cable cleat the top tensioning bolt is made of stainless steel. Ensure that only this bolt is used and that bridging cannot take place. All Atlas cable cleats are supplied with two M12 nuts, bolts and washers.
