In some industrial units forEthernet, the RJ45 contact’s shield is connected to the
chassis via a capacitor, see 1 in drawing above.
The PanelPC’sEthernet shield is directly co
nnected to the chassis, see 2in
drawing above.
1.
Check whether the other Ethernetun it has its shield directly grounded or
grounded via a capacitor.
Note:
Inmany cases,connectingtheshieldedEthernetcablingtothechassisatbothendsis
inappropriate. Humo r groundingloopscanoccur. Unshieldedcablingmayevenresult
infewer communicationerrors.
A good solution may be to usea shielded Ethernet cable, but toconnect the shield
at one end only.
One option is to breakthe shield, see 3 in drawing above.
A more elegant method isto 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 HF transientsto the ground.

• Use shielded cabling for Ethernet,preferably with foil + braided shield.
• D-sub covers should be shielded, and the shield shouldbe connected to the
cover 360 °where the cable comes in.
• Connect the shield at both ends.

With longer distances, there is arisk that the ground potential may be different.
In that case, theshield should only be connected at one end. A good alternative
is to connect the other end of theshield to the ground via a 0.1 uF/250 V plastic
capacitor. Both endsare then connected to the ground in terms ofHF, but only
connected to the groundat one end in terms of LF, thus avoiding the 50Hz
grounding loops.

2.
Place the 24 VD C and communications cabling in one cable trunk/cable duct
and 230/380 V ACin 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 ontothe shielded cabling may removeminor
disturbances. Large ferrite pieces that are snappedonto unshielded cabling and
where the wiresgo 2-4 times around the cores are approximately5-25 times more
efficient.

7.7 CableandBusTerminationRS485
• Use shieldedand twisted pair cable. The pair capacitance may not exceed 52.5
2
pF/m and areaat least 0.25 mm
(AWG 24), if you want to use themaximum
transfer distance and maximum transferspeed.
• 0 V, the reference voltage for communication should beincluded in
the cabling. With two-way communication use two pairs; onepair for
communication and one pair for 0V.
• The shield must be grounded at one end. The other end is usually grounded,
but with longer distances or whenthere is a difference in the ground potential,
theshieldshouldbeconnectedtothegroundvia0.1uF/250Vplastic
capacitor to preventground current in thebraided shield. A number of
manufacturers recommendthat the shield be grounded at each node. Various
manufacturers have different systemsfor bus termination. The RS485
standard does not describehow the “Fail Safe” function would be carried out,
justthatthesystemshouldbeabletohandletheerror.
Depending on the recipients’ design, the buswires may be on the same level or
require pull-up orpull-down to ensure that no faulty signals aredetected when the
bus is in restingmode (all transmitters are disconnected).

Some (older) operator panels hadpull-up and pull-down resistance except for
the actual bus termination at 120 ohm, similar toWestermo and Profibus. See 1
in drawing above.
The PanelPCs have another type of recipient, so-calledb uilt-in “Fail Safe”,where
simple bus termination resistance is sufficient. See 2 in drawing above.
If other nodes on theRS485 network require pull-up andpull-down and the Panel
PC is at one endof the loop, one of the followingprocedures can be carried out:
• Connect two 1k/0.25 W resistors in the25-pole D-sub contact. See 3 in

• Use CAB8. It offers the option of bus terminationwith pull-up/-down. It

Environmental Aspects
10.3 Recycling
The PanelPCs consist largely of aluminum. It is a greatadvantage in terms of both
resources and the environment ifit can be recycled. Make sure that Panel PCs
taken out of service are sent to facilitiesfor electronic scrap.
The manufacturer’s electronic waste is recycled by Stena Technoworld AB.
Aluminum front/rearcasings and other coverscan be removedand recycled.
Plastic display frames and CF coversmust be recycled as hard plastic. The circuit
board contains many valuablemetals 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 asper Handbook 2001:7 (NFS)
and displays as perNFS 2001:8.
Thefluorescenttubemustbehandledashazardouswaste.
The packaging ismade from wood fiber and shouldberecycled. Thelargeprinted
label on the front, however, must firstbe removed as it is made of PVCvinyl. The
label and theplastic bag for the brackets are recycledas soft plastic.
The manufacturer is amember of the REPAregister. The protective film onthe
front is recycled assoft plastic. When the PanelPC is no longer useful it can be
returned to the manufacturer for environmentally responsiblerecycling. 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 thatthe PanelPC contributes to reduced
environmental impact.
Listed below areexamples of how you can reduce environmentalimpact during
Panel PC use.
• Switch thesystem off when not in use.
• Use g reen electricity.
• Use energy-savingoptions, e.g., turn off the backlight to both save energy and
reduce wearon the fluorescent tube.
• If possible, reduce the backlight brightness to reduceenergy consumption
and increase fluorescenttube service life.
