The operator panel’s mounting clamps do not provide a secure grounding
connection between the panel and the device cabinet, see 1 in drawing above.
1.
Connect a wire that is sized correctly according to local electrical codes
between the operator panel’squick-connect plinth and the panel’s chassis, see
2indrawingabove.
2.
Connect a wire or grounding braid that is sized correctly according to local
electrical codes between the operator panel’s chassis and the closest grounding
point on the door, see 3 in drawing above.
3.
Connect a strong but short grounding braid between the door and the device
cabinet,see 4 in drawing above.
4.
Twist the cables onto the 24
V 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 ferritecore suppresses disturbances to the 24 V feed, see 6 in drawing above.
BeijerElectronics, MAEN165

Additional Installation Tips
Note:
The grounding wires should beshort and the conductor shouldhave a large area.
A long, thin grounding w ire hasa very high impedance (resistance) athighfrequencies
and will not guide disturbances tothe ground.
Multi-wireconductors are better thansinglewireconductorswiththesamearea.
A braided conductor wire with the samearea is even better. Thebestisa short, thick
grounding braid.

In some industrial units for Ethernet,the RJ45 contact’s shield is connected to the
chassis via a capacitor, see 1 in drawing above.
The operator panel’s Ethernet shield is directly connectedto the chassis, see 2 in
drawing above.
1.
Check whether the other Ethernet unithas its shield directly grounded or
grounded via a capacitor.
Note:
In many cases, connecting the shieldedEthernet cabling to the chassis atboth ends is
inappropriate. Hum or grounding loops can o ccur. Unshielded cabling mayeven result
in fewer communication errors.
BeijerElectronics, MAEN165
21
Additional Installation Tips
A good solution may be to use a shielded Ethernet 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 toexpand 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 plasticcapacitor,see 5 in
drawing above. This will connect the HF transients to ground.
BeijerElectronics, MAEN165

Additional Installation Tips
6.3 ToAchieveBetterEMCProtection
• Useshielded cables for RS232 communication.
• Usetwisted pair and shieldedcabling for RS422 and RS485.
• Usethe cabling intended 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.
Shielded cable
0.1 μF/250 V
Ground plane 1 Ground plane 2
Ground plate Ground plate in another building
Not same potential
With longer distances, there is a risk that the ground potentialmay 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 μF/250 V plastic
capacitor. Both ends are then connected to the ground in terms of HF, but only
connected to the ground at one end in terms of LF, thus avoiding the 50/60 Hz
grounding loops.

andconnecttheshieldtotheinstallation plate with a 360° metal cable clamp.
2.
Place the 24 V DC an d communications cabling in one cable trunk/cable duct
and 230/380 V AC in another. Ifthe cables need to be crossed, cross them at
90° only. Avoid combiningthe cabling for stronger 24 V DC outputs with
the communicatio n cabling.
Ferritecores that are snapped ontothe shielded cabling may removeminor
disturbances. Large ferrite pieces that are snapped onto unshielded cabling and

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.

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 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 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 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 against the 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 shorter lifespan.
The operator panel’s loss effect = supply voltage x current. Virtually no power g oes
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. See1 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. The operator panel does not have insulation
that meets safety requirements in the event of a potential short circuitbetween
230 V AC and 24 V DC. Itis assumed that the 24 V feed is secure, for example,
SELV according to EN 60950 (protection against electric shock)and UL 950.
Example:
Here is an example thatexplainswhy a secure 24VDC feed can be ruinedby mixing
24 V relay contacts with 230 V AC relay contacts in a smaller controller. Check that the
clearancesand creepage distances between 24 V DCand 230 V AC ful fill EN60950 or
UL 950. Ifnot,input a separate 24V unit into the operatorpanel.
If there is a substa
230 V AC, it is OK t

Connect 0 V on the 24 V feed to the ground, see 4 in drawing above. This offers

The communication ports COM1 and COM2 have built-in galvanic isolation
from the terminal and the input power supply. The communication port grounds
are bonded to protect ive earth ground and therefore to one another. Both Ethernet
ports have galvanic isolation as well. Thereis no galvanic isolation between the
terminal and the input power supply. If galvanic isolation is requiredbetween the
terminal and the power supply an external isolation device is required.
Caution should be taken when connectin g peripherals to the terminal. Many
peripherals including USB devices will bond the terminal’s signal ground (0 V) to
the protective earth ground. Bonding signal ground and protective earth ground
may increase electrical emissionsand introduce communication errors.

Note:
It is very important tomake sure that the 24 V feed in theexternalinsulation unit is not
connected to one ofthe communication outlets. If itdoes not have100%insulation
againstthe 24 V feed,disturbancesand grounding currents from the 0V on the 24 V
side will disrupt communication.
Using this type of unitsolvesone problem but createsa larger problem! A substandard
installationmaywork now, but problems may arise when other devicesareconnected.

Additional Installation Tips
6.7 CableandBusTerminationRS485
• Use shielded and twisted pair cable. The pair capacitance may not exceed
52.5 pF/m and area at least 0.25 mm
2
(AWG 24), if you want to use the
maximum transfer distance and maximum transfer 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 distan ces or when there is a difference in the ground potential,
theshieldshouldbeconnectedtothegroundvia0.1μF/250Vplastic
capacitor to preventground current in the braidedshield. 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).
6.8 COMPortCommon-ModeVoltage
The COM port I/Os have special restrictions for common-mode voltage with
respect to ground.
COMPort Maximum Common-ModeVoltageRange
COM1 - RS232 -15 V to +15 V
COM2 - RS422/RS485 -7Vto+7 V
