1 About this guide
This Quick Start Guide provides basic guidelines for the Rosemount
3490 Controller. Refer to the Rosemount 3490 Reference Manual for
more instructions.
1.1 Safety messages
WARNING
Failure to follow safe installation and servicing guidelines could
result in death or serious injury.
Use the controller only as specified in this Quick Start Guide and the
Reference Manual.
The controller must be installed, connected, commissioned,
operated, and maintained by suitably qualified personnel only,
observing national and local requirements that may apply.
The controller must be installed according to the Rosemount 3490
Product Certifications document.
Before commissioning the controller, ensure that the supply voltage
matches the voltage specifications on the main label.
Repair, e.g. substitution of components, etc. may jeopardize safety
and is under no circumstances allowed.
Electrical shock could cause death or serious injury.
Ensure that the controller is not powered when opening the lid and
making terminal connections.
If the controller is installed in a high voltage environment and a fault
condition or installation error occurs, high voltage may be present on
leads and terminals.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to
and/or misconfiguration of end users’ equipment. This could be
intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and
fundamental in protecting your system. Restrict physical access by
unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.

CAUTION
Pollution protection
Ensure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, ensure that the housing lid is
closed during operation and locked, if necessary.

2 Installation considerations
General
•The controller is classified type A in accordance with
European EMC directive 2014/30/EU. To ensure electro-magnetic
compatibility, in any member country, the controller should not
be installed in a residential area.
•Supply circuits must be limited to the following overvoltage
categories, according to IEC 60664-1:
—Overvoltage category II for 230 V installations
—Overvoltage category III for 115 V installations
Mounting and installation
•Do not mount the controller on a structure that is subject to
vibration, or in a position where damage may be caused by
impact, thermal stress or liquid ingress.
•Do not mount the controller in a position where it might
come into contact with aggressive substances, e.g. acidic liquids
or gases that may attack metals or solvents that may affect
polymeric materials.
•The controller housing is rated IP66/IP67 and Type 4X. It is
suitable for mounting outside, but this should be above any
flood level, away from any overflow path, and away from direct
sunlight.
•The mass of the unit is 3.3 lb (1.5 kg). To conform with safety
requirements, the wall on which the unit is mounted should be
capable of supporting four times this weight.
Wiring
•Ensure that cable glands and connections to the controller are
done in accordance with local and national standards. To maintain
the type 4X rating of the enclosure, type 4X connections must be
used.
•Cable runs should be separate from any high voltage or mains
cables to avoid crosstalk or interference.
•A switch or circuit-breaker must be included in the installation,
suitable located and easily reached. It must be marked as the
disconnecting device for the controller.
•Wires for mains connection should be tied together to prevent
from accidental loosening.

Quick Start Guide 5

•Supply wires shall be suitable for 59 °F (15 °C) above surronding
temperature.

3.2 Keypad
The keypad function buttons are used to navigate through the
software menu system, to configure and setup the controller.
Table 3-1: Keypad Function Buttons
Button Action
The enter button is used to access the menu system, select a
menu option, or to confirm settings.
The up arrow button is used to move upwards when navigating
the menu system, or to scroll through a list of options. When
editing a parameter value, the up arrow button is used to
increase a digit.
The down arrow button is used to move downwards when
navigating the menu system, or to scroll through a list of
options. When editing a parameter value, the down arrow
button is used to decrease a digit.
The left arrow button is used to move left when navigating the
menu system. When editing a parameter value, the left arrow
button is used to move left to another digit.
The right arrow button is used to move right when navigating
the menu system. When editing a parameter value, the right
arrow button is used to move right to another digit.
When navigating the menu system, the back button is used to
return to a previous menu level or the main screen. At other
times, e.g. while editing, the button is used to restore a setting
that is being edited.

5.6 Power consumption
Maximum 20 W
5.7 Grounding
Make sure grounding is done according to national and local
electrical codes. Failure to do so may impair the protection provided
by the equipment. Grounding requirements are dependent on
application type:
Shielded cables
•Connect cable shield to terminal 42 (terminal 71 for sensor input
2)
•Connect terminal 41 to instrument earth/ground point
Unshielded cables
Grounding is not necessary for unshielded sensor cables. Leave
terminals 41, 42 and 71 unconnected.
5.8 Protective earth
The metal support plate should always be grounded in accordance
with national and local electrical codes. Failure to do so may
impair the protection provided by the equipment. The most effective
grounding method is direct connection to earth ground with minimal
impedance. There is a grounding screw connection on the metal
support plate.

5.9 Sensor wire cross-section
Appropriate cross-sectional area of wires must be used in order to
prevent a too high voltage drop to the connected sensor. Use 0.75
mm2 to 2.5 mm2 (18 AWG to 13 AWG) in order to minimize the
voltage drop.
