4 Project planning
4.1 Manufacturer of the machine
The manufacturer of the machinery must carry out a risk assessment and apply appro‐
pr
iate protective measures. Further protective measures may be required in addition to
the product.
The product must not be tampered with or changed, except for the procedures descri‐
bed in this document.
The product must only be repaired by the manufacturer of the product or by someone
authorized by the manufacturer. Improper repair can result in the product not providing
the expected protection.
4.2 Operating entity of the machine
Changes to the electrical integration of the product in the machine controller and
c
hanges to the mechanical mounting of the product necessitate a new risk assess‐
ment. The results of this risk assessment may require the entity operating the machine
to meet the obligations of a manufacturer.
After each change to the configuration, it is necessary to check whether the protective
measure provides the necessary protection. The person making the change is responsi‐
ble for ensuring that the protection measure provides the necessary protection.
The product must not be tampered with or changed, except for the procedures descri‐
bed in this document.
The product must only be repaired by the manufacturer of the product or by someone
authorized by the manufacturer. Improper repair can result in the product not providing
the expected protection.
4.3 Design
Installation site
T
he safety relay must be installed in a control cabinet with an enclosure rating of IP54
or higher.
The safety relay must be installed on a mounting rail (35mm) in accordance with IEC
60715.
Space requirements in the control cabinet
T
o ensure sufficient air circulation and cooling, sufficient distance must be kept in the
control cabinet above and below the safety relay.
Sufficient distance must be kept for the connected cables before the module (front
