Safety

Intended use

The contact expansion module PNOZ s8 meets the requirements of EN 60947-5-1,
EN 60204-1 and VDE 0113-1. It is used to increase the number of safety contacts available
on a base unit. Base units are all safety relays with feedback loop.

The max. achievable safety level depends on the base unit. The expansion module may not
exceed this. The safety-related characteristic values stated under 

Safety-related character-

istic data [

 16]

 can only be achieved if the base unit also exhibits these values.

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 manual,

}

Use of the product outside the technical details (see

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 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.
