Note
All indications including the conductor ferrules.
General note
For lengths of over 10 m, intermediate wire supports must be installed every 3 to 5 m. | Recommended cable lengths for pull-wire Emergency-Stop switches in relation to the range of ambient temperature. | As the thimbles are subject to deformation in case of wire pull, the wire should be pulled several times after fitting. After that, the wire must be re-tensioned using the eyebolt or the tensioner.
