Foreword
All operator panels are developed to satisfy the demands of human-machine
communication. Built-in functions such as displaying and controlling text,
dynamic indication, time channels, alarm and recipe handling are included.
The operator panel works 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 transferredand 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 “the controller” 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.

Safety Precautions
1SafetyPrecautions
Both the installer and the owner and/or operator of the operator panel must read
and understand this installation manual.
1.1 General
• Read thesafety precautions carefully.
• Check the delivery for transportation damage. If damage is found, notify the
supplier as soon as possible.
• Do not use the operator panel in an environment with high explosive hazards.
• The supplier is not responsible for modified, altered or reconstructed
equipment.
• Use only parts and accessories manufactured according to specificationsof
the supplier.
• Read the installation and operating instructions carefully before installing,
using or repairing the operator panel.
• Neverallowfluids,metalfilingsorwiringdebristoenteranyopeningsinthe
operator panel. This may cause fire or electrical shock.
• Only qualified personnel may operate the operator panel.
• Storing the operator panel where the temperature is lower/higher than
recommended in this manual can cause the LCD display liquid to
congeal/become isotopic.
• The LCD display liquid contains a powerful irritant. In case of skin contact,
wash immediately with plenty of water. In case of eye contact, hold the eye
open,flushwithplentyofwaterandgetmedicalattention.
• Thefiguresinthismanualservesanillustrativepurpose. Becauseofthemany
variables associatedwith any particular installation, the supplier cannot
assume responsibilityfor actual use based on the figures.
• The supplier neither guarantees that the operator panel is suitable for your
particular application, nor assumes responsibility for your product design,
installation or operation.
• It is recommended to turn on and shut down the operator panel at least once
before installing any components/cards or beforeconnecting the operator
panel to external devices, like for example serial devices.

1.5 ServiceandMaintenance
• Only qualified personnel should carry out repairs.
• The agreed warranty applies.
• Before carrying out any cleaning or maintenance operations, disconnect the
equipment from the electrical supply.
• Clean the display and surrounding front cover with a soft cloth and mild
detergent.
• Replacing thebattery incorrectly may result in explosion. Only use batteries
recommended by the supplier. During the warranty period, the battery needs
to bereplaced by an authorized Beijer Electronics service center.
1.6 DismantlingandScrapping

inappropriate. Humorgroundingloopscanoccur. Unshieldedcabling mayeven result
infewercommunicationerrors.
BeijerElectronics, MAEN017F
21
Additional Installation Tips
A g ood solution may be to use a shieldedEthernet cable, but to 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 shielded Ethernet 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. This will connect the HF transients to ground.

Additional Installation Tips
6.3 ToAchieveBetterEMCProtection
• Initially, use the original cabling from Beijer Electronics primarily.
• Useshielded cables for RS232 communication.
• Usetwisted pair and shielded cabling for RS422 and RS485.
• Usethe cabling intended for the bustype; Ethernet, Profibus, CC-Link,
CAN, DeviceNet 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, andthe shield should be connected to the
cover 360° where the cable enters.
• Connect the shield at both ends.

2.
Place the 24 V DC and c ommunications cabling in one cable trunk/cable duct
and 230/380 V AC in another. If the cables need to becrossed, cross them at
90° only. Avoidcombining the 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.

6.4 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 the 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-generating devices, the
temperature at the top of the cabinetwill be considerably higher than the
theoretical temperature increase that would be expected. All electronics are
sensitivetoheat. Thelifespanofanelectrolyticcapacitoriscutinhalfwithan
8-10 °Cincrease in temperature. A 15-20 °C temperature increase 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 radiantheat 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 sitsin the cooler area and blows cold air against the operator
panel. If the fan is mounted at the top and sucks warm air upwards, the fan’s
ambient temperature will be higher, resulting in a shorter lifespan.
The operator panel’sloss 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, see2 in drawing above. The operator panel does not have insulation
that meets safetyrequirements 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:

PCPC
When a PC is connected to the operator panel, the panel’sinternal 0 V (GND) will
be connected to the protective ground via the PC.
A number of USB devices can have theshield connected together with the
protective ground. Here,the operator panel’s0 V (GND) is connected to the
protective ground when, for example, a USB memorystick, keyboard or similar
device is plugged in.
If a number of units are connected that have a 0 V and a ground connection, and
these are connected to various grounding points, there is a substantial risk of
problems. Grounding currents go through communication cables, the rear plate
of thecontroller,and internally in the operator panel, and can cause errors.
Use external units to improve communication and achieve galvanic isolation.
Westermo has good industry-standard insulators that are also insulated from the
24 V DC feed.

Additional Installation Tips
6.7 CableandBusTerminationRS485
• If maximumtransfer distance and maximum transf er speed is needed,
shielded and twisted pair cable should be used. The mutual capacitance
may notexceed 52.5 pF/m, andthe 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 mustbe grounded at one end. The other end is usually grounded,
but with longer distances or when there is a difference in the ground potential,
theshieldshouldbeconnectedtothegroundvia0.1μF/250Vplastic
capacitor to prevent ground 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 transmittersare disconnected).
