2 Basic safety instructions
2.1 Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣Are authorized by the plant owner/operator.
‣Are familiar with federal/national regulations.
‣Before starting work, read and understand the instructions in the manual and
supplementary documentation as well as the certificates (depending on the
application).
‣Follow instructions and comply with basic conditions.
The operating personnel must fulfill the following requirements:
‣Are instructed and authorized according to the requirements of the task by the facility's
owner-operator.
‣Follow the instructions in this manual.
2.2 Designated use
Application and measured materials
The device described in these Operating Instructions is a monitoring unit for use with the
Endress+Hauser Micropilot M and Micropilot S-series radars and other HART compatible
devices. Mounted at the tank side, it provides indication of measured data, allows
configuration and supplies intrinsically safe (i.s.) or explosion proof (XP) power to the
connected sensors on the tank. Various industry standard digital gauging communication
protocols support integration into open architecture tank gauging and inventory systems.
Measuring devices for use in hazardous areas, in hygienic applications or in applications
where there is an increased risk due to process pressure, are labeled accordingly on the
nameplate.
To ensure that the measuring device remains in proper condition for the operation time:
‣Only use the measuring device in full compliance with the data on the nameplate and
the general conditions listed in the Operating Instructions and supplementary
documentation.
‣Check the nameplate to verify if the device ordered can be put to its intended use in the
approval-related area (e.g. explosion protection, pressure vessel safety).
‣If the measuring device is not operated at atmospheric temperature, compliance with
the relevant basic conditions specified in the associated device documentation is
absolutely essential.
‣Protect the measuring device permanently against corrosion from environmental
influences.
‣Observe the limit values in the "Technical Information".
The manufacturer is not liable for damage caused by improper or non-designated use.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.

Tankside Monitor NRF81 Basic safety instructions

‣Observe federal/national regulations pertaining to repair of an electrical device.
‣Use original spare parts and accessories from the manufacturer only.
Hazardous area
To eliminate a danger for persons or for the facility when the device is used in the
hazardous area (e.g. explosion protection, pressure vessel safety):
‣Based on the nameplate, check whether the ordered device is permitted for the
intended use in the hazardous area.
‣Observe the specifications in the separate supplementary documentation that is an
integral part of these Instructions.
