} The safety switch and actuator should be installed opposite each other in parallel.
CAUTION!
The unit's properties may be affected if installed in an environment contain-
ing electrically or magnetically conductive material. Please check the oper-
ating distances and the assured release distance.
} Safety switches and actuators should only be secured using M4 screws with a flat head
(e.g. M4 cheese-head or pan head screws).
} The actuator should be protected from unauthorised removal and from contamination.
Close the mounting holes using the seals provided.
} Torque setting: Max. 0.8 Nm.
} The distance between two safety switches must be maintained (see Technical De-
tails [ 20] ).
Safety switches and actuators
} Should not be exposed to heavy shock or vibration and
} Should not be used as a limit stop.
Parallel assembly
Drill holes in the mounting surface (see Di-
mensions [ 19] ) and cut threads in the
holes for M4 screws.
Use a screw to fix the safety switch in place.

safety switch.
2. Attach the screws for the actuator, leav-
ing a distance of 3 … 6 mm between the
screw head and plate.
