Twist the cables onto the 24V DC feed, see 5 in drawing above.
2 turns around the ferrite core provide 4 times the suppression of 1 turn.
3 turns around the ferrite core provide 9 times the suppression of 1 turn.
A ferrite core suppresses disturbances to the 24 V feed, see 6 in drawing above.

In some industrial units for Ethernet, the RJ45 contact’s shield is connected to the
chassis via acapacitor, see 1in drawing above.
The PanelPC’sEthernet shield is directly co
nnected to the chassis, see2 in
drawing above.
1.
Check whether the other Ethernetunit has its shield directly grounded or
grounded via a capacitor.
Note:
Inmanycases,connectingtheshieldedEthernetcablingtothechassis atbothendsis
inappropriate. Humor groundingloopscanoccur. Unshielded cablingmayeven result
infewercommunicationerrors.
A good solution may be to use a shielded Ethernetcable, but to connect the shield
at one end only.
One option is tobreak the shield, see 3 in drawing above.
A more elegant methodis to expand the shielded Ethernet cabling with a piece of
unshielded Ethernetcable, see 4 in drawing above.
You can groundthe shield via an external 0.1 uF/250 V plastic capacitor, see 5 in
drawing above. This will connect the HFtransients to the ground.

Additional InstallationTips
7.3 ToAchieveBetterEMCProtection
• Initially,use the original cabling from Beijer Electronicsprimarily.
• Use shielded cables for RS232 communication.
• Use twisted pair and shielded cabling for RS422 and RS485.
• Use the cabling intended for the bus type; Ethernet,Profibus, CC-Link,
CAN, Device Netetc.
• Install and connect according to applicable specifications for therelevant bus
standard.
• Use shielded cabling for Ethernet,preferably with foil + braided shield.
• D-sub covers should be shielded, and the shield should be connected to the
cover 360 ° where the cable comes in.
• Connect the shield at both ends.

Ground plane 1 Ground plane 2
Ground plate Ground plate
Not same potential
in another building
5352
With longer distances, there isa risk that the ground potential may be different.
In that case, the shield should only be connected at one end. A good alternative
is to connect the other end of the shield to the ground via a 0.1 uF/250 V plastic
capacitor. Both endsare then connected to the ground in termsof HF, but only
connected to the groundat one end in terms of LF, thus avoidingthe 50 Hz
grounding loops.

and connect the shield to the installation plate with a 360 ° metalcable clamp.
2.
Place the 24 VDC and communications cabling in one cable trunk/cable duct
and 230/380 V ACin another. If the cables needto be crossed, 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 removeminor
disturbances. Large ferrite pieces that aresnapped onto unshielded cablingand
where the wiresgo 2-4 times around the cores areapproximately 5-25 times more
efficient.

(AWG 24), if you want to usethe maximum
transfer distance and maximumtransfer speed.
• 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 distances or when there is a difference in theground potential,
theshieldshouldbeconnectedtothegroundvia0.1uF/250Vplastic
capacitor to preventground current inthe braided shield. A number of
manufacturers recommendthat the shield be grounded at each node. Various
manufacturers have differentsystems for bus termination. The RS485
standard does not describe how the “Fail Safe” function would be carried out,
justthatthesystemshouldbeabletohandletheerror.
Depending on the recipients’ design, the bus wires may be on the same levelor
require pull-up or pull-down to ensure that no faulty signals are detected when the
bus is in restingmode (all transmitters are disconnected).

Some (older) operator panelshad pull-up and pull-down resistance except for
the actual bus termination at 120 ohm, similar to Westermo and Profibus. See 1
in drawing above.
The PanelPCs have another type of recipient,so-called built-in “Fail Safe”, where
simple bus termination resistance is sufficient. See 2 in drawing above.
If other nodes on the RS485 network require pull-up and pull-down and thePanel
PC is at oneend of the loop, one of thefollowing procedures can be carried out:
• Connect two 1k/0.25 W resistors inthe 25-pole D-sub contact. See 3 in

10.3 Recycling
The PanelPCs consist largely of aluminum. It is a great advantage in terms of both
resources and the environmentif it can be recycled. Make sure that PanelPCs
taken out of service are sent tofacilities for electronic scrap.
The manufacturer’s electronic waste is recycled by StenaTechnoworld AB.
Aluminum front/rearcasings and other coverscan be removedand recycled.
Plastic display frames and C F covers must be recycled as hard plastic. The circuit
board contains m any valuable metals and should therefore be recycled.
Remove the lithium battery. Electrolytic capacitors and displays are currently not
classified as hazardouswaste, but may be harmful to health and the environment.
The electrolytic capacitors should be handled as per Handbook 2001:7 (NFS)
and displays as perNFS 2001:8.

front is recycledas soft plastic. When the Panel PC is no longeruseful it can be
returned to the manufacturer forenviro nmentally responsible recycling. Contact
the company for further information.
10.4 EnvironmentalImpactReport
A PanelPC impacts the environment through its function, i.e., controlling
industrial equipment. The energy and the scrapped parts that can be saved
with efficient management mean that the Panel PC contributes to reduced
environmental impact.
Listed below areexamples of how you can reduceenvironmental impact during
Panel PC use.
• Switch the system off when not in use.
• Use green electricity.
• Use energy-saving options, e.g., turn off the backlight to both save energy and
reduce wearon the fluorescent tube.
• If possible, reduce the backlight brightness to reduce energy consumption
