Installation manual for T21C
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.
The project can then be transferred and stored in the operator panel itself.
Various types of automation equipment such as PLCs, servos or 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.

7 Additional Installation Tips
When experiencing communication problems in for example noisy environments or when operating close to temperature limits, the following recommendations are to be noticed.

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’s quick-connect plinth and the panel’s chassis, see
2 in drawing above.
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 ferrite core suppresses disturbances to the 24 V feed, see 6 in drawing above.
Beijer Electronics, MAEN084E
25
Additional Installation Tips
Note:
The grounding wires should be short and the conductor should have a large area.
A long, thin grounding wire has a very high impedance (resistance) at high frequencies and will not guide disturbances to the ground.
Multi-wire conductors are better than single wire conductors with the same area.
A braided conductor wire with the same area is even better. The best is a 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 connected to the chassis, see 2 in drawing above.
1. Check whether the other Ethernet unit has its shield directly grounded or grounded via a capacitor.
Note:
In many cases, connecting the shielded Ethernet cabling to the chassis at both ends is inappropriate. Hum or grounding loops can occur. Unshielded cabling may even result in fewer communication errors.
Beijer Electronics, MAEN084E
26
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 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.
Beijer Electronics, MAEN084E

Additional Installation Tips
7.3 To Achieve Better EMC Protection
•
•
•
•
•
•
•
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 Net etc.
Install and connect according to applicable specifications for the relevant bus standard.
Use shielded 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.
Ground plate
Ground plane 1
Shielded cable
0.1 μF/250 V
Ground plane 2
Not same potential
Ground plate in another building
With longer distances, there is a 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 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.
Metal cabinet
Terminal or connector

Cable clamp in steel
EMC cable gland
Shielded cable
Plastic cable gland
Shielded cable
1. Use an EMC cable gland or regular plastic cable gland, remove the outer jacket and connect the shield to the installation plate with a 360° metal cable clamp.
2. Place the 24 V DC and communications cabling in one cable trunk/cable duct and 230/380 V AC in another. If the cables need to be crossed, cross them at
90° only. Avoid combining the cabling for stronger 24 V DC outputs with the communication cabling.
Ferrite cores 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.

In most cases, the ambient temperature for the operator panel is significantly 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 sensitive to heat. The lifespan of an electrolytic capacitor is cut in half with an
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
2 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 temperature will be higher, resulting in a shorter lifespan.
The operator panel’s loss effect = supply voltage x current. Virtually no power goes to external users and no loss effects due to inputs.

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 in drawing above. The operator 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:
Here is an example that explains why a secure 24 V DC feed can be ruined by mixing
24 V relay contacts with 230 V AC relay contacts in a smaller controller. Check that the clearances and creepage distances between 24 V DC and 230 V AC fulfill EN 60950 or
UL 950. If not, input a separate 24 V unit into the operator panel.

If there is a substantial distance between the relay contacts for 24 V DC and
230 V AC, it is OK to use the same 24 V devices for all feeds. See 3 in drawing above.
Connect 0 V on the 24 V feed to the ground, see 4 in drawing above. This offers three advantages:
Safety is increased. The 24 V feed will not be live in the event of a faulty connection or short circuit between 0 V (24 V) and 230 V phase.
Transients on the 24 V feed are connected to the ground.
No risk that the 24 V feed is at a high level in relationship to the ground. This is not unusual since there is high static electricity.

7.6 Cable and Bus Termination RS485
•
•
•
If maximum transfer distance and 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
2
(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 distances or when there is a difference in the ground potential, the shield should be connected to the ground via 0.1 μF/250 V plastic 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 transmitters are disconnected).

Additional Installation Tips
7.7 Boot Priority
The boot priority is the order in which the hardware storage devices are read.
Pressing F7 during boot will display a drop down menu with all available bootable devices.
A change of the boot priority is only temporary. On next startup the boot priority will be restored back to the factory setting.
7.8 Entering BIOS
Caution:
Unless you are an expert computer user, do not change the BIOS settings for this program. Certain changes can cause your operator panel to work incorrectly.
Note:
Before using BIOS setup, it is recommended to write down the setup information for future reference.
Note:
It is recommended to turn on and shut down the operator panel at least once before installing any components/cards or before connecting the panel to external devices, like for example serial devices.
1. Connect a USB Keyboard.
2. Connect power supply and turn on the operator panel.
3. While booting, press the F2 key immediately after the keyboard is initialized.
The initialization is indicated by the keyboard LED's.
If F2 is pressed before the keyboard is initialized, this keystroke will be lost.
If you waited too long and the operating system logo appears, continue to wait until the operating system desktop is appearing. Then, shut down the operator panel and try again.
Note:
The key used to enter the BIOS setup can differ depending on model and CPU Board.
The commonly used keys are ESC, DEL, F1 and F2. For more information, refer to the
BIOS manual.
