WARNING
Incorrect selection of type of protection
Danger of explosion in areas subject to explosion hazard.
This device is approved for several types of protection.
1. Decide in favor of one type of protection.
2. Connect the device in accordance with the selected type of protection.
3. In order to avoid incorrect use at a later point, make the types of protection that are not used permanently

NOTICE
Condensation in the device
Damage to device through formation of condensation if the temperature difference between transportation or storage and
the mounting location exceeds 20 °C (36 °F).
Before taking the device into operation let the device adapt for several hours in the new environment.
•
NOTICE
Ambient temperature too high
Damage to cable sheath.
At an ambient temperature ≥ 60 °C (140 °F), use heat-resistant cables suitable for an ambient temperature at least
•
20 °C (36 °F) higher.
NOTICE
Standard cable gland/torque
Device damage.
Owing the reasons pertaining to tightness (IP enclosure rating) and the required tensile strength, only use the cables
•
having a diameter ≥ 8 mm for standard M20x1.5 cable gland, or use a suitable seal insert in case of smaller diameters.
In the NPT version, the positioner is delivered with a coupling. When inserting a counter piece in the coupling, ensure
•
that the maximum permissible torque of 10 Nm is not exceeded.
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.
