NOTE
Dirt during assembly
Dirty connectors can lead to malfunctions. Protection class IP67 can only be guaranteed if all cables and
connectors are connected.
• Protect the plug connectors against dirt during the assembly.
Mount the module with two M3 screws on the fastening holes in the corners of the module. The fastening
holes have no thread.
4.1.3 Functional earth (FE)
The upper fastening hole also serves as a connection for functional earth (FE).
Make sure that the box is grounded to low impedance via the functional earth (FE) connection. You can
achieve this, for example, by mounting the box on a grounded machine bed.
