Mechanical limit switch modules 6DR4004-6K and -8K

Supply with hazardous voltage
When you supply the non-intrinsically safe version of the module with hazardous voltage, you
must read the following safety rules before starting work on the device:
1. Isolate the device from power. Use a circuit breaker positioned near the device to do this.
2. Make sure that the device cannot be switched back on inadvertently.
3. Make sure the device is truly isolated from power.
Maximum AC/DC switching voltage with UL approval E344532
The mechanical limit switch module 6DR4004-6K is approved for use for positioners with UL
approval. The maximum supply voltage in this case is 30 V AC/DC.
The mechanical limit switch module 6DR4004-8K is not approved for use for positioners with
UL approval.
If this information is ignored, the UL approval for the mechanical limit switch module for the
positioner becomes invalid.
