For your safety
WARNING!
Loss of safety function due to manipulation of the interlocking device
Manipulation of the interlocking device may lead to serious injury and death.
– You should prevent any possibility of the interlocking device being
manipulated through the use of a spare actuator.
– Keep the substitute actuator in a safe place and protect it from unau-
thorised access.
– If spare actuators are used, these must be installed as described in
Installation [ 15].
– If the original actuators are replaced with substitute actuators, the ori-
ginal actuators must be destroyed before disposal.
}Switch off the supply voltage before disconnecting the safety switch from the supply
voltage.
WARNING!
Ignition spark from cable separator/connector within the potentially
explosive area can trigger an explosion
When the cable separators/connectors are used within the potentially ex-
plosive area, sparks can be caused and lead to an explosion.
– Make sure that the cable separators/connectors are used only within
the potentially explosive area.
}The IP protection type (see Technical details [ 18]) has been determined in accord-
ance with DINEN60529 with a safety switch that is as new.

Installation
}The unit can be installed in any position. Safety switches and actuators must be installed
so that the sensing face of the safety switch is exactly opposite the sensing face of the
actuator.
}If possible, do not install the safety switch and actuator on to ferromagnetic material.
Changes to the operating distances are to be expected.
}Make sure that the earthing is in accordance with the specifications in EN60079-14.
CAUTION!
Potential loss of safety function due to changed device properties
The unit's properties may be affected if installed in an environment contain-
ing electrically or magnetically conductive material.
– Please check the operating distances and the assured release dis-
tance.
CAUTION!
Possible loss of the safety function by changing the release distance
Sar with non-flush installation
Installing the safety switch non-flush within electrically or magnetically con-
ductive material, the value for the assured release distance Sar can change.
– Check the assured release distance Sar.
}Safety switches and actuators must be positioned so that they are secured against a
change of position.
}The safety switch and actuator should only be secured using screws and nuts made of
non-magnetic material (e.g. brass or stainless steel).
}Avoid the risk of damages from foreseeable external influences by attaching the safety
switch and actuator. If necessary, safety switch and actuator have to be protected.

INFORMATION
Protect the actuator from unauthorised removal (e.g. via a screw lock or
concealed installation) and from contamination.
}Prevent self-loosening of the fastening elements of safety switch and actuator.
}The fastening of safety switch and actuator has to be sufficiently stable to ensure the
proper operation of the safety switch and the actuator.
}The distance between two safety switches must be maintained (see Technical
details [ 18]).
}Safety switches and actuators
– Should be kept away from iron swarf
– Should not be exposed to strong magnetic fields
}Prevent the safety switch and actuator being exposed to heavy shock or vibration.
}Make sure that the safety switch and actuator cannot be used as an end stop.
}Circumvention of the safety switch in a reasonably foreseeable manner must be preven-
ted.
}Please note the installation measures in accordance with EN ISO 14119 for a proximity
switch type 4 with coding level Low.
}Alignment errors of the guard must not adversely affect the safety function of the guard.
}The assured operating distance Sao and the assured release distance Sar must be tested
under real conditions.
}Do not apply any installation tools (e.g. Pliers) on the surfaces of the switch.
}Protect the safety switch from UV light or direct sunlight.
}Any metallic parts (also accessories) must be connected to the equipotential bonding in
case of a risk of charging.
