device to manufacturer)

Safety instructions

• Check whether the spare part matches the labeling on the
measuring device as described on the cover page.
• The spare part sets and Installation Instructions are used to
replace a faulty unit with a functioning unit of the same
type.
Only use original parts from Endress+Hauser.
• Comply with national regulations governing mounting,
electrical installation, commissioning, maintenance and
repair procedures.
• The following requirements must be met with regard to
specialized technical staff for the mounting, electrical
installation, commissioning, maintenance and repair of the
measuring devices:
– Specialized technical staff must be trained in instrument
safety.
– They must be familiar with the individual operating
conditions of the devices.
– In the case of Ex-certified measuring devices, they must
also be trained in explosion protection.
• The measuring device is energized! Risk of fatal injury from
electric shock. Open the measuring device only when the
device is de-energized.
• When using Ex-certified measuring devices: Open device
only when in a de-energized state (allow 10 minutes to
elapse 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:
Commission in accordance with Operating Instructions after
repair. Document the repair procedure.
• Before removing the device: set the process to a safe state
and purge the pipe of dangerous process substances.
• Hot surfaces! Risk of injury! Before commencing work: allow
the system and measuring device to cool down to a
touchable temperature.
Additional safety instructions for PMD75 with small measuring ranges (10 mbar, 30 mbar) and a
glass cover
For reasons of electromagnetic compatibility (EMC), the original glass cover must be replaced on measuring devices with a
new 10 mbar or 30 mbar sensor. The need to replace the cover is checked at the factory. If a new coated glass cover is
supplied with the delivery, this cover must be used.

abrasion-proof dry lubricant is not available. Use acid-free,
non-hardening lubricant.
• 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).
