General notes
Instruction manual
•This instruction manual applies to the NMT538 with V.6x software installed.
•Please read this manual carefully and make sure you understand its contents before using the
product.
•This manual is solely intended to describe product functions and should not be used for any
other purpose.
•No part of this manual may be reproduced or reprinted without permission.

•This manual waspreparedwith the highest degree of care. However, should you find any errors
or have any questions, contact one of our service offices or your local sales agent.
Product Requirements
Power source
Check the voltage of the power supply before connecting it to the product. It should be the exact
voltage required for proper operation of the product.
Use in hazardous areas
When using the product in a first or second-class hazard location (Zone 1 or Zone 2) be sure to
use an intrinsically safe or pressure- and explosion-proof apparatus. Take the utmost care during
the installation, wiring, and piping of such an apparatus to ensure the safety of the system. For
safety reasons, maintenance or repairs on the product while it is being used with such on
apparatus should only be performed by qualified personnel.
External connection
When an external connection is required, the product should be protectively grounded before it
is connected to a measurement object or an external control circuit.

1 Safety instructions
1.1 Designated use
The Prothermo NMT538 temperature signal converter is designed to be connected to RTD type
Intrinsically safe average temperature probe. Use for purpose other than originally intended may
cause failure. Failure may occur if the inappropriate probe is connected or as a result of improper
operation. Carefully read this instruction manual before attempting to use the NMT538 and
connection to the desired temperature probe.
Caution!
Before opening the cover of the Prothermo NMT538 for maintenance, switch off the power supply
of the Proservo NMS53x or the Tank side monitor NRF590.Eitherof described instruments are the
host gauge for supplying DC voltage on the HART line.
1.2 Installation, commissioning and operation
•Mounting,electricalinstallation,start-upandmaintenanceoftheinstrumentmayonlybecarried
out by trained personnel authorized by the operator of the facility.
•Personnel must absolutely and without fail read and understand this Operating Manual before
carrying out its instructions.
•The instrument may only be operated by personnel who are authorized and trained by the
operator of the facility. All instructions in this Manual are to be observed without fail.
•The installer has to make sure that the measuring system is correctly wired according to the
wiring diagrams. The measuring system is to be grounded.
•Please observe allprovisions valid for your country and pertaining to theopening and repairing
of electrical devices.
1.3 Operational safety
Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of this Operating Manual. Strict compliance with the
installation instructions and ratings as stated in this supplementary documentation is mandatory.
•Ensure that all personnel are suitably qualified.
•Observe the specifications in the certificate as well as national and local regulations.
Fcc approval
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1)This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
Caution!
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
1.4 Return
The following procedure must be carried out before a transmitter is sent to Endress+Hauser for
repair.
•Always enclose a duly completed "Hazardous Substance Data sheet" form. Only then can
Endress+Hauser transport, examine and repair a returned device.
•Enclose special handling instructions if necessary, for example a safety data sheet as per
EN 91 / 155 / EEC.
•Remove all residue which may be present. Pay special attention to the gasket grooves and
crevices where fluid may be present. This is especially important if the fluid is dangerous to
health, e.g. corrosive, poisonous, carcinogenic, radioactive, etc.
Note!
A copy of the "Hazardous Substance Data sheet" is included at the end this operating manual.

Caution!
•No instrument should be sent back for repair without all dangerous material being completely
removed first, e.g. in scratches or diffused through plastic.
•Incomplete cleaning of the instrument may result in waste disposal or cause harm to personnel
(burns, etc.). Any costs arising from this will be charged to the operator of the instruments.
1.5 Notes on safety conventions and symbols
In order to highlight safety-relevant or alternative operating procedures in the manual, the
following conventions have been used, each indicated by a corresponding symbol in the margin.
Protection from line noise.
Symbol Meaning
Warning
A warning highlights actions or procedures which, if not performed
correctly, will lead to personal injury, a safety hazard or destruction
of the instrument.
Caution!
Caution highlights actions or procedures which, if not performed
correctly, may lead to personal injury or incorrect functioning of the
instruments.
Note!
A note highlights actions or procedures which, if not performed
correctly, may indirectly affect operation or may lead to an
instrument response which is not planned.
Device certified for use in explosion hazardous area
If the Micropilot has this symbol embossed on its name plate it can
be installed in an explosion hazardous area.
Explosion hazardous area
Symbol used in drawings to indicate explosion hazardous area.
- Devices located in and wiring entering areas with the designation
"explosion hazardous areas" must conform with the stated type of
protection.
Safe area (non-explosion hazardous area)
Symbol used in drawings to indicate, if necessary, non-explosion
hazardous areas.
- Devices located in safe areas still require a certificate if their
outputs run into explosion hazardous areas.
Direct voltage
A terminal to which or from which a direct current or voltage may
be applied or supplied
Alternating voltage
Aterminaltowhichor fromwhichanalternating(sine-wave)current
or voltage may be applied or supplied
Grounded terminal
A grounded terminal, which as far as the operator is concerned, is
already grounded by means of an earth grounding system.
Protective grounded (earth) terminal
A terminal which must be connected to earth ground prior to
making any other connection to the equipment.
Equipotential connection (earth bonding)
A connection made to the plantgrounding system which may be of
type e.g. neutral star or equipotential line according to national or
company practice
