1 INSTALLATION AND CONNECTION
Only qualified staff is allowed to perform the installation. All legal rules have to
be observed and technical standards have to be met. Before connecting the
device check that all connecting leads are de-energized and that current
transformers are bypassed.
1) Compare auxiliary-, measurement-, control voltage, frequency and the current path of the
device (see type label) with the data of the electricity network.
2) Assemble the relay in the switch panel with the 2 mounting clips. If the device is not
fitting in the cut out the small plastic bars on the side of the case can be removed with a
knife.
3) Connect protective ground to the terminal link of the case.
4) Connect in accordance to the wiring diagram. Pay special attention to the cross section
size of the CT connections! A combined power supply and measurement ensures a safe
shutdown of capacitors at low voltage.
5) Remove short circuit links of the current transformer.

2 COMMISSIONING
2.1 Commissioning manual:
After the supply voltage is applied, in ESTAmat PFC-N starts a countdown with 90 sec.
Cancel the countdown by pressing the (esc) button. Enter the “SETUP” menu and control
respectively adjust the parameters. To enter the “SETUP” menu, please follow the arrows (
) as shown at menu 4.4. All parameters of the “SETUP” menu are explained in the
corresponding chapter.
2.2 Commissioning automatically:
During the countdown, the auto-initialization can be start by pushing the ( ) button.
Automatic initialization is switching all exits. During this test it can get information, which
exits are working and it can correct the connection of the measuring channels for voltage and
current by internal settings.
Automatic initialization can be started only when the voltage and current are ok. Settings of
c/K value and the switching sequence is not required.
When mains conditions are not suitable for auto-initialization, it will be interrupted. The
controller shows the message
„Ai Abrt“. If multiple repetition do not lead to any result, the following chapters shall be
considered.
Display „Auto“: Indication „Auto“ shows that the control is working. If „Auto“ is not
displayed then control function is stopped. This can happen for the following Reasons:
manual mode is active, control function is switched off, temperature is to high, measured
current is less than 15mA, voltage or the harmonic content is outside the admissible range.
Over-and undervoltage monitoring: The ESTAmat PFC-N is equipped with an over and
undervoltage monitoring. The admissible voltage range refers to the adjusted nominal voltage.
If the measured voltage is outside of the admissible range the message U Alarm appears.
Then the setting of nominal voltage has to be adapt to local ratings. The nominal voltage is
independent of the connection always the line voltage.
Activation of the measured value display: see chapter 4.1

4.2 Info (Step database)
In the "INFO" menu for each connected step the number of switching cycles, the current step
size and the step size in relation to the initial step size is stored.
Using these data, conclusions can be drawn on the condition of the site and the condition of
single step's. Step sizes are shown in kVar only when in the CT ratio is set in "Setup"
menu.

4.3 Manual (step switching manual)
To enter in manual mode, please select “manual” in main menu and push ► for 3 seconds. By
entering this submenu the manual mode for the regulator is active. The automatic control is
stopped and the exits can be switched manually. By the means of the -keys the
referring step can be selected. Changing the switching state is possible by pushing the ►-key.
Manual switching is only possible when measurement voltage is in allowed
range. Otherwise over- and undervoltage protection will block this function.
After switching off an active step the discharge time is active. Only after this
time is over the step can be switched on manually again.
