used in applications with:
} E-STOP pushbuttons
} Safety gates
} Light grids and safety switches with detection of shorts across contacts
The following is deemed improper use in particular
} Any component, technical or electrical modification to the product,
} Use of the product outside the areas described in this operating manual,
} Use of the product outside the technical details (see Technical details [ 17]).
NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product
may cause interference if installed in other environments. If installed in other
environments, measures should be taken to comply with the applicable
standards and directives for the respective installation site with regard to in-
terference.
Safety regulations
Safety assessment
Before using a device, a safety assessment in accordance with the Machinery Directive is
required.
The product as an individual component fulfils the functional safety requirements in accord-
ance with EN ISO 13849 and EN 62061. However, this does not guarantee the functional
safety of the overall plant/machine. To achieve the relevant safety level of the overall plant/
machine’s required safety functions, each safety function needs to be considered separ-
ately.

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 T
M
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
The unit meets all the necessary conditions for safe operation. However, please note the
following:
} Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120
VDC) are present on the unit, connected control elements and sensors must have a rated
insulation voltage of at least 250 V.
