1 Safety Instructions
• Comply with national regulations governing mounting, electrical
installation, commissioning, maintenance and repair procedures.
• Requirements with regard to specialized technical staff for the
mounting, electrical installation, commissioning, maintenance and
repair of the measuring devices:
– trained in instrument safety
– familiar with the individual operation conditions of the devices
– for Ex-certified measuring devices: also trained in explosion
protection
• The spare parts set and Installation Instructions are used to replace
a faulty unit with a functioning unit of the same type.
Use genuine parts from Endress+Hauser only.
• Using the material number and identification information, check
whether the spare part matches the identification label on the
measuring device.
• If you have any questions, contact your E+H service organization.
• Modifications of the measuring device are not permitted.
• Follow the Operating Instructions for the device.
• Before removing the device: set the process in a safe condition and
purge the pipe of dangerous materials.
• Hot surfaces! Risk of injury! Before commencing work, allow the
system and measuring device to cool down to a touchable temperature.
• In the case of measuring devices in custody transfer applications, the
custody transfer status no longer applies once the lead seal has been
removed.
• In the case of measuring devices in safety-related applications in
accordance with IEC 61508 or IEC 61511: After repair recommission in
accordance with Operating Instructions. Document the repair procedure.
• In the case of Ex-certified measuring devices: Only open in
a de-energized state (once a delay of 10 minutes has elapsed after
switching off the power supply) or in environments which do not
have a potentially explosive atmosphere.

• After removing the electronics cover, there is a risk of electric shock
as shock protection is removed!
Switch off the measuring device before removing internal covers.
• Service connector:
– do not connect in potentially explosive atmospheres.
– only connect to Endress+Hauser service devices.
• Only open housing for a brief period. Avoid the penetration of foreign
bodies, moisture or contaminants.
• Replace defective seals/gaskets with genuine parts from
Endress+Hauser only.
• Threads (e.g. of the cover for the electronics and connection
compartments) must be lubricated. Use an acid-free, non-hardening
grease if an abrasion resistant dry lubricant is non-existent.
• If threads are damaged or defective, the measuring device must be
repaired.
• If spacing is reduced or the dielectric strength of the measuring device
cannot be guaranteed during repair work, perform a test on
completion of the work (e.g. high-voltage test in accordance with the
manufacturer's instructions).
• Risk of damaging electronic components! Ensure you have a working
environment protected from electrostatic discharge.
• Caution! When replacing amplifier boards, I/O boards or
submodules, ensure compatibility with existing software. The process
for reading out the software revision number is described in the
Operating Instructions (device functions). If the software of the board
is not compatible, it should be updated using an operating software
package (e.g. Field Care). In the event of functional changes, notify
the plant owner/operator.
• The measuring device is energized. Danger: Risk of electric shock!
Open the measuring device in a de-energized state only.
• Observe the instructions for transporting and returning the device
outlined in the Operating Instructions.
