1 Safety instructions
Safe operation of the device is only guaranteed if these Operating Instructions have been read and
the safety instructions they contain have been observed.
1.1 Designated use
The process transmitter evaluates analog process variables, converts signals and shows them on its
multicolored display. Using the unit's outputs and limit relays, processes can be monitored and
controlled. The device is equipped with a wide range of software functions for this purpose.
Power can be supplied to 2-wire sensors with the integrated transmitter power supply system.
– The device is seen as an associated apparatus and may not be installed in hazardous areas.
– The manufacturer accepts no liability for damages resulting from incorrect use or use other than
that designated. The device may not be converted or modified in any way.
– The device has been designed for use in an industrial environment and may only be operated in
an installed state.
1.2 Installation, commissioning and operation
This device is designed to meet state-of-the-art safety requirements and complies with applicable
standards and EU regulations. The device can be a source of application-related danger if used
improperly or other than intended.
Installation, wiring, commissioning and maintenance of the device must only be carried out by
trained technical personnel. The technical personnel must have read and understood these
Operating Instructions and must strictly follow the instructions they contain. The information in the
electrical wiring diagrams (see Operating Instructions, Section 4 'Wiring') must be observed closely.
1.3 Operational safety
Technical improvement
The manufacturer reserves the right to adapt technical details to the most up-to-date technical
developments without prior notice. Contact your sales center for current information and updates
to these Operating Instructions.

2.3 Certificates and approvals
CE mark, Declaration of Conformity
The process transmitter is designed to meet state-of-the-art safety requirements, has been tested and
left the factory in a condition in which it is safe to operate. The device meets the relevant standards
and directives as per EN 61 010-1 "Safety requirements for electrical equipment for measurement,
control and laboratory use".
Thus, the device described in these Operating Instructions meets the legal requirements of the EU
directives. The manufacturer confirms successful testing of the device by affixing to it the CE mark.
An overview of all the certificates and approvals available can be found in Section 10 "Technical
data".
3 Installation
3.1 Incoming acceptance, transport, storage
The permitted ambient and storage conditions must be observed. The precise specifications can be
found in Section 10 "Technical data".
3.1.1 Incoming acceptance
On receipt of the goods, check the following points:
• Are the packaging or contents damaged?
• Is anything missing from the delivery? Compare the scope of delivery with the information you
specified in the order.
3.1.2 Transportation and storage
Note the following points:
• Pack the device so that is protected against impact for storage and transportation. The original
packaging provides optimum protection.
• The permitted storage temperature range is -40 to +85°C (-40 to +185 °F); it is possible to store
the device in the limit temperature ranges for a limited period (maximum 48 hours).
3.2 Installation conditions
The process transmitter is designed for use on the top-hat rail (IEC 60715 TH35).
Connections and outputs are provided on the top and underside of the device. Inputs are located
on the top, while outputs and the power supply connection are located on the underside of the
device. The wires are connected by means of labeled terminals.
Operational temperature range:
-20 to 50 °C (-4 to 122 °F)
"Caution!
• To avoid heat accumulation, always make sure the device is sufficiently cooled.
• If the device is operated in the upper temperature limit range, this reduces the operating life of
the display.
3.2.1 Orientation
Vertical.

RMA42 Installation
Endress+Hauser 9
1. Push the upper top-hat rail clip upwards and the lower clip downwards until the clips engage
in position.
2. Position the device on the top-hat rail from the front.
3. Slide the two top-hat rail clips together until they engage in position.
To disassemble the device push the top-hat rail clips upwards or downwards (see 1.) and remove
the device from the top-hat rail. Also only one clip can be opened and the device can be tilted
accordingly to remove it from the top-hat rail.
3.5 Post-installation check
• Is the top-hat rail clip engaged?
• Is the device securely fixed to the top-hat rail?
• Are all the plug-in terminals securely locked in place?
• Are the temperature limits observed at the installation location (see Section 3.2)?

4 Wiring
#Warning!
Make sure that no voltage is supplied when wiring the device.
"Caution!
• Prior to commissioning, make sure the supply voltage matches the specifications on the
nameplate.
• Provide a suitable switch or power-circuit breaker in the building installation. This switch must
be provided within easy reach of the device and be labeled as a disconnector.
• An overcurrent protection unit (nominal current = 10 A) is required for the power cable.
!Note!
• Observe the terminal designation on the rear of the device.
• It is permitted to connect a mixture of safety extra low voltage and voltage which poses a shock
hazard to the relays.
4.1 Connecting the device
A loop power supply system (LPS) is provided for every input. The loop power supply system is
primarily provided to supply power to 2-wire sensors and is galvanically isolated from the system
and the outputs.
