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.
• In the case of measuring devices in custody transfer, the custody
transfer status no longer applies once the lead seal has been
removed.

Protective Cover connection compartment
• Risk of damaging electronic components!
Ensure you have a working environment protected from electro-
static 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.
• Caution! When replacing amplifier boards, I/O boards or submo-
dules, 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 upda-
ted using an operating software package (e.g. Field Care). In the
event of functional changes, notify the plant owner/operator.
• Replace defective seal/gaskets with genuine parts from
Endress+Hauser only.
• If threads are damaged or defective, the measuring device must
be repaired.
• Threads (e.g. of the cover for the electronics and connection com-
partments) 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.
• If you have any questions, contact your Endess+Hauser service
organization.
