ardous area following a protection violation if personnel are still in the hazardous area.
Prevent circumvention of the protected field. This means that other safety devices and safe-
guards may be required in addition to the safety light grid. These should be determined via
a safety assessment based on the specific application area and specific local conditions
(e.g. official specifications).
Refer to IEC/TS 62046 to determine other necessary safeguards for securing the hazard-
ous area.

Safety assessment

Before using a unit 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.
