4.1
Manufacturer of the machine
DANGER
Failure to comply with manufacturer’s obligations
Hazard due to lack of effectiveness of the protective device
b
Carry out a risk assessment before using the safety controller.
b
Do not manipulate, open or modify the components of the safety controller.
b
Make sure the safety controller is only repaired by the manufacturer or by some‐
one authorized by the manufacturer. Improper repair can lead to a loss of the
protective function.
4.2
Operating entity of the machine
DANGER
Failure to observe operator obligations
Hazard due to lack of effectiveness of the protective device
b
Changes to the machine and changes to the hardware or the logic programming
of the safety controller necessitate a new risk assessment. The results of this risk
assessment may require the entity operating the machine to meet the obligations
of a manufacturer.
b
Apart from the procedures described in this document, the components of the
safety controller must not be opened or modified.
b
Do not carry out any repair work on components. Improper repair of the safety
controller can lead to a loss of the protective function.
4.3
Design
Mounting
•
Environment meets the requirements of IP54 or higher, e.g., IP54 control cabinet.
•
Mounting on a 35 mm × 7.5 mm mounting rail in accordance with IEC 60715.
•
The mounting rail is connected to the functional earth.
•
Mounting rail is mounted on a mounting plate.
•
Mounting plate is connected to functional earth.
•
Mounting in a vertical orientation (on a horizontal mounting rail).
•
Take suitable ESD protection measures.
Air circulation
To ensure sufficient air circulation and cooling, sufficient distance must be kept in the
control cabinet above and below the module.
Provide an adequate clearance in front of the module (front side) for the connected
cables.
