Note (General)

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.

At 2 m ... 5 m distance intermediate wire supports are required, see accessories

The screwed G24-M20 indicator lamp must be ordered separately, see accessories.
