• 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 protection concepts 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.
Only use genuine parts from Endress+Hauser.
• 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 to the measuring device are not permitted.
• Follow all measuring device documentation.
• In the case of Ex-certified measuring devices: Comply with the installation
instructions and operating conditions in the supplementary Ex-documentation.
• Before removing the device, stop the process and purge the pipe of dangerous
gases and liquids.
• 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 safety-related applications in accordance
with EN 61508 or EN 61511, reconfigure and test following any repair.
Document the repair procedure in accordance with the applicable standard(s).
• 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.
• To regain the (explosion) protection of the measuring device:
– seal the openings with genuine covers
– seal cable entries with approved components suitable for the (explosion)
protection.
• Replace defective seal/gaskets by 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.
• Danger: Risk of electric shock! Only open the measuring device
in a de-energized state.
• Observe the instructions for transporting and returning the device outlined in
the Operating Instructions.
