WARNING
Explosion Hazard!
‣
Please refer to the separate documentation on applications in hazardous areas for the
safety instructions.
For optimum electromagnetic compatibility:
• Keep the potential matching line as short as possible
• Maintain a cross-section of at least 2.5 mm

The thread of the electronics and connection compartment is coated with lubricant
varnish.
Avoid additional lubrication.

Supply voltage
• Ex d, Ex e, non-Ex: supply voltage: 10.5 to 35 V
DC
• Ex i: supply voltage: 10.5 to 30 V
DC
• Nominal current: 4 to 20 mA HART
The power unit must be tested to ensure it meets safety requirements (e.g., PELV, SELV,
Class 2) and must comply with the relevant protocol specifications. The requirements for
4 to 20 mA are the same as those for HART.
Depending on the supply voltage and the current consumption, Bluetooth can optionally be
switched on or off. For the dependency, see the diagram:
