Observe the following recommendations for secure operation of the product.
General
▪ Ensure that only authorized personnel have access to the device.
▪ Only use the device within an ESP (electronic security perimeter). Do not
connect the device to the Internet in an unprotected state. Use mecha-
nisms for vertical and horizontal network segmenting and security gate-
ways (firewalls) at the transition points.
▪ Ensure that the device is only operated by trained personnel who are fa-
miliar with IT security.
Commissioning
Observe the following recommendations for device commissioning:
▪ User IDs must be unique and assignable. Do not use a "Group account"
function or the "Auto login" function.
▪ Activate the "Auto logout [►Section 8.2.6, Page 87]" function.
▪ Restrict the rights of the individual user groups as much as is feasible; this
helps avoid errors during operations. A user with the "Operator" role, for
example, should only perform operations and should not be able to
change any device settings.
▪ Delete or disable the default "admin" user ID. This requires first creating a
new user account with the "Administrator" role. You can then use it to
delete or disable the default "admin" account.
▪ Deactivate service user access [►Section 8.2.7, Page 88].
▪ Enable SSL/TLS encryption [►Section 8.2, Page 86]; access to the de-
vice is then only possible using the SSL/TLS protocol. In addition to en-
crypting communication, this protocol also checks the authenticity of the
server.
▪ Use TLS version 1.2 or higher wherever possible.
▪ Integrate the device into a public key infrastructure. Create your own SSL
certificates for this if necessary and then import it.
▪ Connect the device to a central log server by using the syslog interface
[►Section 8.21, Page 222].
Operation
Observe the following recommendations during device operation:
▪ Change the password at regular intervals.
▪ Export the security log [►Section 8.25.1, Page 238] at regular intervals.
▪ Check the log files regularly for unauthorized system access and other se-
curity-related events.

4.2 Function description of the voltage regulation
The TAPCON® is used to keep the output voltage of a three-winding transformer constant. The three-winding transformer consists of one high voltage
winding and two undervoltage windings. The high voltage winding has an
on-load tap-changer.
The TAPCON® measures the voltage of the two undervoltage windings. The
voltage is regulated on either of the two windings. The device configuration
determines which winding is regulated. The non-regulated winding is still
monitored for the set limit values.
Figure3: Overview of voltage regulation of a three-winding transformer
Maschinenfabrik Reinhausen GmbH 2019 234077638/07 EN TAPCON
®
Page 24
4 Product description
To regulate the voltage, the TAPCON® compares the measured voltage of
the active undervoltage winding U
The difference between U
actual
and U
with a defined desired voltage U
actual
is the control deviation (dU).

5 Packaging, transport and storage
5 Packaging, transport and storage
5.1 Suitability, structure and production
The goods are packaged in a sturdy cardboard box. This ensures that the
shipment is secure when in the intended transportation position and that
none of its parts touch the loading surface of the means of transport or touch
the ground after unloading.
The box is designed for a maximum load of 10kg.
Inlays inside the box stabilize the goods, preventing impermissible changes
of position, and protect them from vibration.
5.2 Markings
The packaging bears a signature with instructions for safe transport and correct storage. The following symbols apply to the shipment of non-hazardous
goods. Adherence to these symbols is mandatory.

5.3 Transportation, receipt and handling of shipments
In addition to oscillation stress, jolts must also be expected during transportation. In order to prevent possible damage, avoid dropping, tipping,
knocking over and colliding with the product.
If a crate tips over, falls from a certain height (e.g. when slings tear) or is
subject to an unbroken fall, damage must be expected regardless of the
weight.
Every delivered shipment must be checked for the following by the recipient
before acceptance (acknowledgment of receipt):
▪ Completeness based on the delivery slip
▪ External damage of any type
The checks must take place after unloading when the crate or transport container can be accessed from all sides.
®
Maschinenfabrik Reinhausen GmbH 201944 4077638/07 ENTAPCON
Page 45
5 Packaging, transport and storage
Visible damage If external transport damage is detected on receipt of the shipment, proceed
as follows:
▪ Immediately record the transport damage found in the shipping docu-
ments and have this countersigned by the carrier.
▪ In the event of severe damage, total loss or high damage costs, immedi-
ately notify the sales department at Maschinenfabrik Reinhausen and the
relevant insurance company.
▪ After identifying damage, do not modify the condition of the shipment fur-
ther and retain the packaging material until an inspection decision has
been made by the transport company or the insurance company.
▪ Record the details of the damage immediately onsite together with the
carrier involved. This is essential for any claim for damages!
▪ If possible, photograph damage to packaging and packaged goods. This
also applies to signs of corrosion on the packaged goods due to moisture
inside the packaging (rain, snow, condensation).
▪ Be absolutely sure to also check the sealed packaging.
Hidden damage When damages are not determined until unpacking after receipt of the ship-
ment (hidden damage), proceed as follows:
▪ Make the party responsible for the damage liable as soon as possible by
telephone and in writing, and prepare a damage report.
▪ Observe the time periods applicable to such actions in the respective
country. Inquire about these in good time.
With hidden damage, it is very hard to make the transportation company (or
other responsible party) liable. Any insurance claims for such damages can
only be successful if relevant provisions are expressly included in the insurance terms and conditions.
5.4 Storage of shipments
When selecting and setting up the storage location, ensure the following:
▪ Protect stored goods against moisture (flooding, water from melting snow
and ice), dirt, pests such as rats, mice, termites and so on, and against
unauthorized access.
▪ Store the crates on timber beams and planks as a protection against ris-
ing damp and for better ventilation.
▪ Ensure sufficient carrying capacity of the ground.
▪ Keep entrance paths free.
▪ Check stored goods at regular intervals. Also take appropriate action after
storms, heavy rain or snow and so on.

6.2.4 Information about shielding the CAN bus
In order for the CAN bus to operate faultlessly, you have to connect the
shielding using one of the following variants. If you are not able to use any of
the variants detailed below, we recommend using fiber-optic cables. Fiberoptic cables decouple the devices and are not sensitive to electromagnetic
interference (surge and burst).
NOTICE
Damage to the device!
If you connect the CAN bus cable to devices with different potentials, current may flow across the shielding. This current may damage the device.
► Connect the devices to a potential equalization rail to equalize the poten-
tial.
► If both devices have different potentials, only connect the CAN bus cable
shielding to one device.
Variant 1: The connected devices share the same potential
If the devices to be connected share the same potential, proceed as follows:
1. Connect all devices to a potential equalization rail to equalize the poten-
tial.
2. Connect the CAN bus cable shielding to all connected devices.
Variant 2: The connected devices have different potentials
Note that the shielding is less effective with this variant.
If the devices to be connected have different potentials, proceed as follows:
► Connect the CAN bus cable shielding to just one device.
Connecting shielding
Connect the shielding for the CAN bus cable to the 9-pin D-sub connector:

▪ To obtain a better overview when connecting cables, only use as many
leads as necessary.
▪ Note the connection diagram.
▪ Only use the specified cables for wiring. Note the cable recommendation.
6.5.1 Cable recommendation
Please note the following Maschinenfabrik Reinhausen recommendation
when wiring the device.
6 Mounting
Excessive line capacitance can prevent the relay contacts from breaking the
contact current. In control circuits operated with alternating current, take into
account the effect of the line capacitance of long control cables on the function of the relay contacts.
If you want to route Ethernet connections from a control cabinet or building,
we recommend the use of fiber-optic cables (in accordance with the
IEC61850-90-4 recommendation).

7.5.3 Checking parallel operation
This section describes how you can run the function test for parallel operation.
Requirements To obtain perfect functioning in parallel operation, the TAPCON® must be
commissioned in simplex mode. Make sure that the conditions below have
been fulfilled.
▪ All TAPCON® units are set to the same operating parameters for "desired
value" and "delay time T1" [►Section 8.4.3, Page 106]
▪ "Activate parallel operation" [►Section 8.11.2.1, Page 141] parameter set
to ON
▪ Parallel operation method selected.
▪ A different CAN bus address [►Section 8.11.2.3, Page 142] (≠ 0) is set
for all TAPCON®
▪ The same parallel operation group input is set for all TAPCON®
7.5.3.1 Setting circulating reactive current sensitivity
This section describes how you set the circulating reactive current sensitivity
to check the function of the "circulating reactive current minimization" parallel
operation method.
Maschinenfabrik Reinhausen GmbH 2019 794077638/07 EN TAPCON
®
Page 80
7 Commissioning
Note that the following prerequisites must be met for the "circulating reactive
current minimization" parallel operation method:
▪ You have to use current transformers with the same rated values for all
transformers in parallel operation.
▪ If you wish to operate in parallel operation with existing devices, you have
to activate the Retrofit TAPCON® 2xx [►Section 8.11.3, Page 144] parameter.
Consult the section Circulating reactive current minimization for more information.
To set the circulating reactive current sensitivity, proceed as follows:
1. Select the "Circulating reactive current" parallel operation method.
2. Set circulating reactive current sensitivity to a value of 0%.
3. If necessary, activate the Retrofit TAPCON® 2xx function [►Section
8.11.3, Page 144].
4. Adjust both transformers in simplex mode to the same actual voltage using on-load tap-changers.
5. Connect the transformers in parallel and enable the parallel control.
ð The status display in the Parallel operation menu lights up blue.
ð The two TAPCON® must be within the bandwidth.
6. Set the desired value of both TAPCON® to the voltage currently measured [►Section 8.4.1, Page 91].
7. On one of the two transformers, raise the tap position of the on-load tapchanger by one setting; on the second transformer, lower the tap position
of the on-load tap-changer by one setting.
ð The two TAPCON® are still within the bandwidth.
8. Increase the circulating reactive current sensitivity in small steps until the
control deviation dU in the main screen is outside the bandwidth (depending on TAPCON® greater than or less than the bandwidth).
9. Press to select auto mode for all TAPCON® units.
ð All of the TAPCON® units return the on-load tap-changer units to the
original tap positions.
If an on-load tap-changer does not switch back to its original tap position,
you have to increase the circulating reactive current sensitivity.
If one of the on-load tap-changer units switches one or more tap positions
higher and the other switches the same amount lower, you need to reduce
the circulating reactive current sensitivity.
After you have set the circulating reactive current sensitivity, continue with
the function test for the circulating reactive current blocking limit described in
the next section.

7.5.3.2 Testing the circulating reactive current blocking limit
This section describes how to run the function test for circulating reactive
current blocking.
ü Set the circulating reactive current blocking limit to a value of 20%.
1. Press on a TAPCON® to select manual mode.
2. Using manual control, adjust the relevant motor-drive unit upwards (for example 1...2 steps) by the maximum permitted tap difference in operating
positions between the parallel operating transformers.
When setting the circulating reactive current blocking in the following
process step, wait approximately 2 to 3 seconds between the individual
steps.
3. In the Parallel operation > Parallel operation method menu item, set
the circulating reactive current parallel operation method.
4. Reduce the circulating reactive current blocking limit parameter from the
set value of 20% in steps of 1% until the message Circulating reactive cur-
rent blocking limit exceeded is displayed.
ð Any further regulation is blocked.
ð After the set delay time for the parallel operation error message has
elapsed, the circulating reactive current blocking message is displayed.
5. Increase the circulating reactive current blocking limit parameter again until the message Circulating reactive current limit exceeded disappears.
6. Press to select auto mode.
ð The motor-drive unit automatically returns to the original operating posi-
tion.
7. Set the value determined for the "circulating reactive current blocking
limit" for the TAPCON® units in parallel operation as well.
If one TAPCON® or all of the TAPCON® units indicate Circulating reactive
current blocking limit exceeded even though the control inputs are correctly
connected for all TAPCON® units, all of the TAPCON® units block.
This could be due to various causes. Further information is given in the
chapter Troubleshooting [►Section 10, Page 268].
ð The function test for the circulating reactive current blocking limit is com-
plete.
7.5.3.3 Checking tap synchronization method

Page 82
7 Commissioning
In parallel operation in accordance with the Automatic tap synchronization method, the tap positions of the transformers running in parallel are
compared. It is therefore necessary that the transformers have the same
position designation and that the Raise and Lower signals produce the
same voltage change in all transformers.
NOTICE
Damage resulting from formation of circulating reactive current
If the parameters are not set correctly, damage may result from the formation of circulating reactive current and the resulting overload of transmission
lines and transformers.
► Check transformer nameplate.
► Set TAPCON® parameters in accordance with the configuration of the
transformers.
Before starting the function test, you must carry out the following steps:
1. Assign the master function to one TAPCON®.
2. Assign the follower function to the other TAPCON® units.
3. Compare the tap position displays of master and follower . All of
the TAPCON® units must display the same tap position. If this is not the
case, switch all TAPCON® units to the same tap position.

8.4.1.7 Active power-dependent adjustment of desired voltage value with 3
different desired values
The TAPCON® Dynamic Setpoint Control (TDSC) function is used to adapt
the desired voltage value depending on the measured active power. This allows you to compensate for a voltage drop during increased load or an increase in voltage due to a decentralized feed-in.
The device provides you with 3 different sets of parameters for this purpose.
Depending on the selection of the desired value 1, 2 or 3, the device uses
the parameter set 1, 2 or 3 for TDSC.
