Installing a cable-operated switch with actuation on both sides

3SE7160-1AE...
1. Remove the plastic sheath from the wire clamping area before you attach the pull-wire.
Install the pull-wire as described in the installation instructions.
2. Pretension the wire until the operating lever of the cable-operated switch is aligned
horizontally (mid-position).
3. After installing the switch, pull the wire forcefully several times as the wire eyes deform
when the wire is pulled. Tension the wire using a wire clamp or by means of a turnbuckle.
4. The cable-operated switch must be installed in such a way that it can be safely unlatched by
hand.
5. Adjust the tension springs in such a way that the cable-operated switch is tripped at the
opposite end if the wire breaks or becomes detached.
Limitation of travel of tension springs
Make sure that the tension spring is not under maximum tension. Proper functioning of the
cable-operated switch cannot otherwise be guaranteed.
Note
The 3SE7160 cable-operated switches for actuation on both sides must always be mounted
centrally so that the wire length is the same on both sides.
