2.3 Destination and use
Pull-wire switches are used to give signals to start machines and to
open or close electrically-driven doors and gates. If the pull-wire is
pulled, the switching function of the pull-wire switch is activated.
AWG 14, Solid/Stranded. Max. torque: 7 in. lb.
Use copper conductors only.
3. Mounting
3.1 General mounting instructions
The installation may only be carried out by authorised personnel.
The pull-wire switch is fitted by means of four screws (distance of the
drill holes 30 mm or 60 mm).
3.2 Assembly layout
The pull-wire switch must be fitted vertically. (Pull wire with ball
available as accessory.)
