8.1 Important information
NOTICE
Install the safety switch and actuator so that the possibilities of defeat are
reduced to a minimum (see guidelines for reducing the possibilities for de-
feating interlocking devices in EN ISO 14119).
NOTICE
Install safety switch and actuator so that it is not possible to reach through
with hand or finger.
} The fastening of safety switch and actuator has to be sufficiently stable to ensure the
proper operation of the safety switch and the actuator.
} Prevent the safety switch and actuator being exposed to heavy shock or vibration.
} The mounting surfaces for safety switches and actuators can have a max. unevenness of
0.5 mm.
} The actuator must rest flush on the mounting surface.
} The safety switch and actuator should be installed opposite each other in parallel.
} After installation, at least one of the auxiliary releases/escape releases must be operated.
} Use the same type of screw to attach the safety switch and actuator.
} Use non-removable flat head locking screws to attach the safety switch and actuator (e.g.
cheese-head or pan head screws) or rivets.
} For a minimum screw depth of 6 mm, M5 screws with resistance class 8.8 should be
used to attach the safety switch and actuator.
} For a minimum screw depth of 7.2mm, M6 screws with resistance class 8.8 should be
used to attach the L-bracket.
} Prevent self-loosening of the fastening elements,
– On the safety switch: By complying with the max. torque setting (see Technical
details [ 65]).
– On the actuator: By complying with the max. torque setting (see Technical
details [ 65]) and medium-strength threadlockers.
} Pilz recommends that you use the PSEN ml actuator center ring (see Order
reference [ 75]) only with small door radiuses (see Install the safety switch horizont-
ally at a swing gate [ 33]).
} Torque setting: Please note the information provided under Technical details [ 65].
Don’t fully tighten the safety screws until the safety switches and actuators are correctly
aligned and the function has been tested (see Adjustment [ 52]).
} Installation of the safety switch and actuator must be concealed.
