• Caution! When replacing the amplifier board, I/O board or submodules, ensure
compatibility with the installed software. The procedure for reading out the software
version number is described in the Operating Instructions (device functions). If the printed
circuit board' s software is not compatible, an update must be performed using an operating
software tool (e.g. Field Care). Notify the plant operator in the event of functional changes.
• Replace defective seals only with original seals from Endress+Hauser.
• If threads are damaged or defective, the measuring device must be repaired.
• Threads (e.g. of the electronics compartment cover and connection compartment cover)
must be lubricated if an abrasion-proof dry lubricant is not available. Use acid-free, non-
hardening lubricant.
• If, during modification, spacing is reduced or the dielectric strength of the measuring device
cannot be guaranteed, perform a test on completion of the work (e.g. high-voltage test in
accordance with the manufacturer' s instructions).
• Service plug:
– Do not connect in explosive atmospheres.
– Only connect to Endress+Hauser service devices.
• Observe the instructions for transporting and returning the device outlined in the Operating
