CAUTION
Incorrectly connecting the device can damage it.
For device connection, the data given in the connection diagram must be complied with
(see chapter “Connection diagram”) and the connection lines must be voltage-free. When
wiring, always ensure that all wiring material used is neither damaged nor defective and
that the polarity is correct!
Proper and safe operation of the product requires correct transport, storage, installation
and assembly as well as careful operation and maintenance.
If the device has any visible damage it is considered unt for use and must be disconnect-
ed from the mains!
Troubleshooting, repairs and maintenance work may only be carried out at our plant or
after contacting our customer service team. If the device is opened without authoriza-
tion, any warranty or guarantee claim is forfeited. Correct functioning can no longer be
guaranteed!
Opening the device may expose live parts. Capacitors in the device may still be charged,
even if the device has been disconnected from all power sources. Do not operate open
devices under any circumstances!
Systems that are at risk from lightning strikes must feature lightning protection for all
input and output lines.

Functions
2 Description of functions of the multicomp F144-3PH
The multicomp F144-3PH reactive power controller works automatically in 4-quadrant
operation (generator operation), i.e. even with energy recovery to the utility company
network, missing compensation power is detected without a problem and compensated.
The control type of the device is optimizing, i.e. the controller selects the switching stage
with the suitable compensation capacity according to the missing compensation power.
By using the "maximum switching power per switching operation" parameter (menu
Extra / Commissioning / max. switching power), you can dene how many kvar the
controller can switch (on and o) at the same time. This enables faster compensation. If
the set value is smaller than the largest switching stage available, the value of the largest
stage is automatically used as the switching criterion.
Through the integrated temperature measurement input, the ambient temperature in
the reactive power compensation system is also monitored and if a predened limit tem-
perature is exceeded, the fan is switched on. Furthermore, you can protect the system by
setting an alarm / switch-o temperature which switches it o if there is a risk of damage
due to overtemperature.
The controller is additionally equipped with a limit monitoring function for protection of
capacitors from overvoltage and excessive harmonic load of voltage and current.
The 3-phase voltage and current recording makes it possible to not only realize 3-phase
compensation as before, but also real single-phase compensation (balancing) or a mix-
ture of single-phase and 3-phase compensation.
In this context, it is possible to separately congure 3-phase, phase-phase and sin-
gle-phase stages for each of the 18 existing compensation stages.
Furthermore, it is also possible to operate a compensation system with capacitive stages
only, inductive stages only or in mixed mode.
For 3-phase measurement, the measuring values are displayed separately per phase,
making it possible to evaluate the actual power supply conditions in detail. For sin-
gle-phase measurement, the measuring values of the phase measured are displayed but
the power values are additionally projected as total power.
By using an additional digital input, it is possible to activate a second deviating target
CosPhi.
Furthermore, the device is equipped with a RS485 bus interface for operation at the KBR
eBus with the visual energy computer software. This enables comfortable visualization of
the measuring values and the controller's operating state as well as convenient congu-
ration of the device via the primary control unit.

Functions
Alternatively, this serial interface can also be accessed via Modbus (RTU). A detailed de-
scription can be found in the “Modbus data point description,” available separately.
Please also observe the following notes on start-up and operation:
In case of operation in a 3-wire network, a zero-point creator is required (e.g. 700/100 V
AC, primary 3-phase connection, available from KBR), as the controller needs a neutral
conductor for trouble-free operation.
For operation as a single-phase measuring controller, the measuring current must always
be connected at the terminals 20 und 21 (k1 and l1). After changing to single-phase oper-
ation, you can congure the phase shift between the measuring current and measuring
voltage (menu Commissioning / Transformer / Main current transformer).
In this case, the measuring voltage must be connected to terminals 10 (L1) and 13 (N).
For this operating mode, the compensation system only may have 3-phase stages, as
single-phase measurement is projected to 3-phase operation.
If the measuring current is taken from a phase other than the measuring voltage, this
shift can be adjusted under the menu item Extra / Commissioning / Transformer / Main
current transformer / Phase I (0°, 120°,240°)
The following settings are possible:
U L1, I
L1 =0° U L2, I L2 =0° U L3, I L3 =0°
U L1, I
L2 = 120° U L2, I L3 = 120° U L3, I L1 = 120°
U L1, I
L3 = 240° U L2, I L1 = 240° U L3, I L2 = 240°

Installation
NOTE
A phase-phase measurement (2 measuring phases without neutral conductor) is not
possible with this device.
NOTE
For mixed operation of contactor stages and thyristor stages of the same size, the thyris-
tor stages should be assigned to the stages in the back, as the front stages are switched
rst. The thyristor stages are detected if the discharge time set is under 1 second.
After 60 seconds, an active thyristor stage is replaced by a comparable contactor stage (if
available) for continuous operation. This way, quick compensation is guaranteed even in
case of fast load changes.
For mixed operation of phase-phase and phase-N stages, the largest phase-N stage must
not be larger than the largest phase-phase stage. The smallest single-phase stage should
only be half the size of the smallest phase-phase stage.
For mixed operation of phase-N stages and 3-phase stages, the largest 3-phase stage
must be larger than the combination stage consisting of phase-N stages.
For mixed operation of phase-phase-phase stages and 3-phase stages, the largest
3-phase stage must be larger than the combination stage consisting of phase-phase
stages.
For single-phase compensation (only phase-N stages or only phase-phase stages),
3-phase measurement needs to be programmed

3.1 Installation and assembly
The applicable VDE regulations must be observed during installation!
Before the device is connected to the power supply, check whether the local power
supply conditions comply with the specications on the nameplate. Incorrect connec-
tion may result in the destruction of the device. A dierent power frequency inuences
the measurement accordingly.
The device must be connected in accordance with the connection diagram.
The power supply input of systems that are at risk from lightning strikes must be
equipped with suitable lightning protection.
CAUTION
The control voltage as well as the applied measuring voltage of the device must be pro-
tected by means of a back-up fuse.
When connecting the current transformers, the energy ow direction and the correct
assignment to the voltage path must be observed!
NOTE
When connecting the phase (L1) to terminal 1 and the neutral conductor (N) to terminal 2
(Ph-N100V – 240V+/-10 % 50Hz/ 60 Hz/DC) the safety device and the disconnector in the
supply line to terminal 2 (N) are not required.
The safety device and the disconnector to terminal 2 (N) are only required for the follow-
ing connection variants:
Alternating voltage:
Terminal 1 (L1) and terminal 2 (L2):
US1 Phase-Phase 100V - 240V +/-10% 50Hz/60 Hz

Connection
3.2 Current transformer connection:
When mounting the transformer, observe the direction of the current or energy ow. If
the current transformer is mounted the wrong way, the measured current value will be
negative.
A prerequisite for this is that energy is supplied to the device.
The following points must be observed when connecting the device:
Direction of the energy ow
Assignment of measuring voltage input / current transformer input
The current transformer on terminal 20/21 (k1/l1) must be installed in the phase in which
the measuring voltage for terminal 10 (L1) is measured.
The device will display positive current when connection
and energy ow direction are correct.
If connected incorrectly, the current displayed is negative.
Interchange the connections until the display shows correct values.
