Mechanical limit switch modules 6DR4004-6K and -8K
Supply with hazardous voltage
DANGER
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.
CAUTION
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.
