Safety instructions
• Check whether the spare part matches the identification
label on the measuring device, as explained on the first page.
• 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.
• 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 measuring device is energized. Danger: Risk of electric
shock! Open the measuring device in a de-energized state
only.
• 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.
• 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.
• 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.
Additional safety instructions
During exchange of spare part set you may be exposed to ionizing radiation.
• Contact your responsible radiation safety officer for particular instruction.
• Avoid any unnecessary exposure to radionation.
• Keep unavoidable exposure to radiation as low as possible.
• Observe the instructions on radiation protection in the Operating Instructions TI00435F (FQG61, FQG62) or BA01327F

• In the case of measuring devices in custody transfer, the
custody transfer status no longer applies once the lead seal
has been removed.
• Follow the Operating Instructions for the device.
• Risk of damaging electronic components! Ensure you have a
working environment protected from electrostatic discharge.
• 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.
• Modifications to the measuring device are not permitted.
• Only open housing for a brief period. Avoid the penetration
of foreign bodies, moisture or contaminants.
• Replace defective seal/gaskets with genuine parts from

• 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 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).
• Service connector:
– Do not connect in potentially explosive atmospheres.
– Only connect to Endress+Hauser service devices.
• Observe the instructions for transporting and returning the
device outlined in the Operating Instructions.
