Remaining risks (EN ISO 12100-1)
The circuit proposals as shown in this manual have been tested and checked with the
highest possible care. The current standards and guidelines are fulfilled if using the shown
components and the corresponding wiring. Remaining risks are present if:
• the proposed circuit concept is changed and the connected safety-relevant components
or protective devices are possibly not or insufficiently included in the safety circuit.
• the user did not comply with the current safety regulations for operation, adjustment and
maintenance of the machine. Strict compliance with the intervals for checking and
maintenance of the machine is mandatory.
