Installationmanual foriXT21C
Foreword
All operator panelsare developed to satisfythe demands ofhuman-machine
communication. Built-in functionssuch as displayingand controlling text,
dynamic indication, timechannels, alarm andrecipe handling areincluded.
The operator panelworks primarily in an object-oriented way,making it easy to
understand and use. Configuration is carried out on a PC using the iX Developer
configuration tool. The project can then be transferred and stored in the operator
panel itself.
Various types of automation equipment such PLCs, servosor drives can be
connected to the operator panels. In this manual,the term “thecontroller” refers
to the connected equipment.
This manual explains how to install the operator panel. Please refer to the
iX Developer reference manual for further information.

Additional Installation Tips
A good solution may be to use a shielded Ethernet cable, butto connect the shield
at one end only.
One option is to break the shield, see 3 in drawing above.
A more elegant method is to expand the shieldedEthernet cabling with a piece of
unshielded Ethernet cable, see 4 in drawing above.
The shield can be grounded via an external 0.1 μF/250 V plastic capacitor, see 5 in
drawing above. Thiswill connect the HF transients to ground.

Additional Installation Tips
7.3 ToAchieveBetterEMCProtection
• Initially, use the original cabling from Beijer Electronics primarily.
• Useshielded cables for RS232 communication.
• Usetwisted pair and s hielded cabling for RS422 and RS485.
• Usethe cablingintended for the bus type; Ethernet, Profibus, CC-Link,
CAN, Device Net etc.
• Install and connect according to applicable specifications for the relevant bus
standard.
• Useshielded cabling for Ethernet, preferably with foil and a braided shield.
• D-sub covers should be shielded, and the shield should be connected to the
cover 360° where the cable enters.
• Connect the shield at both ends.

andconnecttheshieldtotheinstallation plate with a 360° metal cable clamp.
2.
Place the 24 V DC and communications cabling in one cable trunk/cableduct
and 230/380 V AC in another. If the cables need to be crossed, cross them at
90° only. Avoid combiningthe cabling for stronger 24 V DC outputs with
the communication cabling.
Ferritecores that are snapped onto the shielded cabling may remove minor
disturbances. Large ferrite pieces that are snapped onto unshielded cabling and
where the wires go 2-4 times around the cores are approximately 5-25 times more
efficient.

7.4 AmbientTemperature
The maximum ambient temperature for the operator panel is provided in the
specifications. The ambient temperature refers to the temperature in the device
cabinet which cools t he operator panel’s electronics.

Inmostcases,theambienttemperaturefortheoperatorpanelissignificantly
higher than the device cabinet’s ambient temperature.
If the cabinet is tall and there are a number of heat-generatingdevices, the
temperature at the top of t he cabinet will be considerably higher than the
theoretical temperature increase that would be expected. All electronics are
sensitivetoheat. Thelifespanofanelectrolyticcapacitoriscutinhalfwithan
8-10 °C increase in temperature. A 15-20 °C temperatureincrease results in a
quarter of the lifespan etc.
Rittal has a good program for estimating the anticipated average temperature in
the cabinet as well as a large program for controlling the temperature in the device
cabinet.

An enamel-coated steel cabinet has a radiant heat value of 5.5 W/m
and degrees
C.
Installing a fan inside the cabinet will even out the temperature, while moving air
provides considerably better cooling than still air.
Install the fan so that it sits in the cooler area and blows cold air againstthe operator
panel. If the fan is mounted at the top and sucks warm air upwards, the fan’s
ambient temperaturewill be higher,resulting in a shorterlifespan.
The operator panel’s loss effect = supply voltage x current. Virtually no power goes
to external users and no loss effects due to inputs.

Additional Installation Tips
If a power supply that meets safety standards is used and only feeds the operator
panel, there is no problem. See 1 in drawing above.
However, if a 24 V unit that also feeds other units is used, there is reason to be
cautious, see 2 indrawing above. Theoperator panel does not have insulation
that meets safety requirements in the event of a potential short circuit between
230 V AC and 24 V DC. It is assumed that the 24 V feed is secure, for example,
SELV according to EN 60950 (protection against electric shock) and UL 950.
Example:

7.6 CableandBusTerminationRS485
• If maximum transfer distanceand maximum transfer speed is needed,
shielded and twisted pair cable should be used. The mutual capacitance
may not exceed 52.5 pF/m, and the cable area should be at least 0.25 mm
(AWG 24).
• 0 V, the reference voltage for communication should be included in
the cabling. With two-way communication use two pairs; one pair for
communication and one pair for 0 V.
• The shield must be grounded at one end. The other end is usually grounded,
but with longer distancesor when there is a difference in the ground potential,
theshieldshouldbeconnectedtothegroundvia0.1μF/250Vplastic
capacitor to preventground current in the braided shield. A number of
manufacturers recommend that the shield be grounded at each node. Various
manufacturers have different systems for bus termination.
Depending on the recipients’ design, the bus wires may be on the same level or
require pull-up or pull-down to ensure that no faulty signals are detected when the
bus is in resting mode (all transmitters are disconnected).
