CAUTION
A faulty connection can lead to the destruction of the device!
For device connection, the data given in the connection chart must be complied with
(see„Connection chart“) and there must be no voltage in the connection lines. When
wiring, always ensure that all wiring material used is neither damaged nor defective and
that the polarity is correct!
In order to ensure proper and safe product operation, it must be transported, stored, ins-
talled and assembled in accordance with the specications, as well as carefully operated
and maintained.
A visibly damaged device must generally be considered unt for use and disconnected
from the power supply!
Error detection, repair and maintenance work may only be carried out in our facilities or
after contacting our service team. Opening the device unauthorized shall render your
warranty null and void. Correct operation can no longer be guaranteed!
Opening the device may expose live parts. Capacitors in the device may still be under
load, even if the device has been disconnected from all voltage sources. Open devices
must not be operated!
Systems that are at risk from lightning strikes must feature lightning protection for all
input and output lines!

2.1 Installation and assembly
The applicable DIN / VDE regulations must be observed for 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.
A faulty connection can lead to the destruction of the device! A dierent power fre-
quency inuences the measurement accordingly.
The device must be connected in accordance with the connection chart.
Systems that are at risk from lightning strikes must feature lightning protection for all
input and output lines!
CAUTION
The control voltage as well as the applied measuring voltage of the device must be
protected by means of a back-up fuse.
When connecting the current transformer, the energy ow direction and the correct
assignment to the voltage path must be observed!
During installation, please also observe our notes on safety measures against overvoltage
and lightning in the chapter„Protective measures“ of this manual.

NOTE
The following points must be observed when connecting the device:
- Energy ow direction
- Assignment of measuring voltage input/current transformer input
Energy ow direction: When mounting the transformer, observe the current ow or
energy ow direction. If the current transformer is mounted the wrong way round, the
measured current will be negative.
Prerequisite is that energy is consumed.
Assignment - measuring voltage input / current transformer input:
The current transformer on terminal 20/21 (k1/l1) must be arranged in the phase where
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 connec-
tions until the display shows correct values.
CAUTION
Before any interchanging, the current transformer must be shorted out!

Terminal:
1 (L) and 2 (N): Power supply connection
A control voltage is required to supply the device with power.
The unit is equipped with a multi-range power supply and may
be supplied by voltages of 100 – 240V ± 10% DC 50/60 Hz (see
nameplate for device voltage).
10 (L1,Lx):
13 (N,Ly):
Voltage measuring input
Input voltage both as PH-N and PH-PH measurement.
Direct measurement for 100... 500...600V AC. The measuring ran-
ge is congurable. Exceeding the measuring interval results
in an error message.
For higher voltages, connection via voltage transformers is
necessary (medium voltage measurement x/100 V), measuring
range from 500V to 30.0 KV Ph-Ph.
20 (k1) and 21 (l1): Measuring input for current
The measuring input for current must be connected via a current
transformer x/1A AC or x/5A AC.
When connecting the transformer, pay attention to the energy
ow direction and to the correct assignment of measuring volta-
ge input to current transformer.
30 (C) and 31 (S): Floating relay contact
This contact serves as a message or alarm output. During
operation, an audible or visual message may be activated or a
consumer switched o. The contact is open as long as the device
is dead as well as when there is an active message. Maximum
switching capacity 2A at 250V AC.
40 (C): Connection for voltage supply to the relay output terminals
41 to 45
The relays for the control outputs share the same connection to
the supply voltage.

Terminal:
41 (K1) to 45 (K5): Non-oating relay contacts
These contacts are used as control outputs for the capacitor
switching contactors. As long as the device is dead and for
stages that are not hooked up, the contacts are open. Maximum
switching capacity 2A at 250V AC.
51 (-) and 52 (+): Temperature sensor input
A temperature sensor, e.g. PT1000, can be connected to this
input to measure the switchgear cabinet temperature.
Temperature measuring range of – 20°C to 100°C +/- 2°C.

3 Start-up guidelines for the multicomp D6-xxx-7
This guideline helps you to correctly start up the compensation controller multicomp
D6-xxx-7. It provides you with step-by-step instructions to help you nd the options
relevant for you in the operating instructions.
To begin with, there are two cases in which the start-up procedure for the
multicomp D6-xxx-7 diers.
Case 1: You have bought a complete compensation system from KBR, and the controller
is already installed. If this is the case, certain settings are already precongured in the
controller.
Case 2: You only bought the controller, or the controller with additional modules
(multisio D2-1T2RO, multisio D2-4RO, multisio D2-4CI and multimess D4) and individual
capacitor stages, but the system is not assembled. In this case, the controller is delivered
with the default settings (refer to chapter Default settings) and has thus not been precon-
gured.

3.1 Controller not precongured
If an uncongured controller is to be started up, the following procedure has to be per-
formed step by step.
1. Conguring additional modules
(multisio D2-1T2RO, multisio D2-4RO, multisio D2-4CI and multimess 14)
If there are no additional temperature, relay or induced current measuring modules, this
step can be skipped. To congure additional modules, connect them and the supplied
bus line to the basic module. The additional modules can then be activated individually
using a scan mode, which has to be triggered via the basic module‘s operating panel
and the DIP switches or scan buttons on the additional module. If the compensation unit
consists of several cabinets, the correct cabinet assignment has to be set up.
Detailed instructions for this step are given in chapter Settings under Modules / Display
submenu.
2. Conguring current transformer values
For the compensation controller to function properly, all current transformer parameters
have to be set correctly. Primary and secondary current of the transformer have to be set.
These parameters can be read on the nameplate of the current transformer. In addition,
the phase assignment of the transformer has to be set correctly. In the controller, the
phase (L1, L2, L3) in which the current transformer is integrated has to be set.
You can nd more detailed information on this topic in chapter Start-up under Transfor-
mer settings submenu.
3. Setting target cosine:
You can ask your energy supply company for the target cosine, which should be set up
at this point. The target cosine is by default set to 0.95 inductive (see chapter Default
settings).
You can nd more detailed information on this topic in chapter Start-up under Target
cosine submenu.
