Safety regulations
Safety assessment
Before using a device it is necessary to perform a safety assessment in accordance with
the Machinery Directive.
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.
Use of qualified personnel
The products may only be assembled, installed, programmed, commissioned, operated,
maintained and decommissioned by competent persons.
A competent person is a qualified and knowledgeable person who, because of their train-
ing, experience and current professional activity, has the specialist knowledge required. To
be able to inspect, assess and operate devices, systems and machines, the person has to
be informed of the state of the art and the applicable national, European and international
laws, directives and standards.
It is the company’s responsibility only to employ personnel who
}Are familiar with the basic regulations concerning health and safety / accident prevention,
}Have read and understood the information provided in the section entitled Safety
}Have a good knowledge of the generic and specialist standards applicable to the specific
application.
Warranty and liability
All claims to warranty and liability will be rendered invalid if
}The product was used contrary to the purpose for which it is intended,
}Damage can be attributed to not having followed the guidelines in the manual,
}Operating personnel are not suitably qualified,
}Any type of modification has been made (e.g. exchanging components on the PCB
boards, soldering work etc.).
Disposal
}In safety-related applications, please comply with the mission time TM in the safety-related
characteristic data.
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).

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 [ 13].
– If the original actuators are replaced with substitute actuators, the ori-
ginal actuators must be destroyed before disposal.
}Do not remove the connector's protective cap until you are just about to connect the unit.
This will prevent potential contamination.
}The connector should be protected from accidental loosening (e.g. using a cable tie).
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 [ 17]) has been determined in accord-
ance with DINEN60529 with a safety switch that is as new.
Unit features
}The actuator PSEN 2.1-20 belongs to the safety switch.

Function description
If the actuator is within the response range (safety gate closed), the safety contacts of the
safety switch are closed and the LED will go out.
Operate the PSEN 2.1p-24, ATEX in conjunction with the following components:
}Actuator PSEN 2.1-20 (see Order reference [ 19]) and
}a connected evaluation device (see Requirements and connection to evaluation
devices [ 10]).

Wiring
}Information given in the Technical details [ 17] must be followed.
}Calculation of the max. cable length lmax:
Rlmax - Ri
Rl / km
Imax =
Rlmax = Max. overall cable resistance (see evaluation device's technical details)
Ri = Internal resistance sensor (see Technical details [ 17])
Rl/km = Cable resistance/km of the cable (seetechnical details cable)
}Ensure the wiring and EMC requirements of EN 60204-1 are met.
}Refer to the notes on wiring in EN60079-14.
}Depending on which evaluation device is used, the overall cable resistance must be
checked; before commissioning it may also be necessary to check the cross circuit detec-
tion function.
}Ensure that the safety switch's electrical connections cannot work loose.
}Protect the safety switch's electrical connections from corrosion.
}The safety contacts are not short circuit-proof.

}UL requirement: the supply voltage must be provided via a Class 2 power supply.
WARNING!
Ignition in a potentially explosive area!
Unintentionally removing the connector while voltage is applied may trigger
an explosion, causing serious injury and death.
– Switch off the supply voltage before removing the connector.
– Protect the connector from being removed unintentionally.
