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.
• Printed circuit boards for devices in categories II1G, II1D, II 2G, II 2D, Zone
1 and Class I, Div. 1, Gp. A, B, C, D have a recess/printed circuit board
coding. It is not permitted to break off the coding because the explosion
protection would no longer apply as a result.

• 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.
