The purpose of this manual is to assist during the installation, start-up and maintenance of
OPTIM P&P series low voltage (LV) capacitor banks switched by contactors. Carefully read the
manual to achieve the best performance from those units.
3.- INSTALLATION
3.1.- PRELIMINARY RECOMMENDATIONS
In order to use the unit safely, it is critical that individuals who handle it follow the
safety measures set out in the standards of the country where it is being used,
use the personal protective equipment necessary, and pay attention to the various warnings indicated in this instruction manual.
Installation or maintenance personnel should read and understand this manual
before operating the unit.
A copy of this manual should always be available to maintenance personnel for
reference purposes
Connecting the unit to the public mains must be carried out in compliance with
the EN-IEC60204-1 standard, regarding the safety of LV electrical installations.
It is recommended that several personnel are present when handling the unit for
installation or maintenance.
If damage or faults are detected during unit operation, or in circumstances that
compromise safety, immediately stop work in that area and disconnect the unit in
order to check it without voltage.
The manufacturer of the unit is not responsible for any damage resulting from failure by the
user or installer to heed the warnings and/or recommendations set out in this manual, nor for
damage resulting from the use of products or accessories that did not come with the unit or that
were made by other manufacturers.
If an anomaly or malfunction is detected in the unit, do not use it to perform any operation.
Modifying, upgrading or rebuilding the unit without written authorisation from the
manufacturer is prohibited.
The installation, operation and maintenance of low voltage (LV) units must only
be carried out by authorised installers. LV regulations (Art. 22) specically dene
the requirements that authorised installers must meet.

Instruction Manual
OPTIM P&P Series
Do not access the active elements of a capacitor bank with static operation that
has been powered and might have voltages present. Wait at least 5 minutes after the power supply has been disconnected.
Do not touch the terminals or active parts of the unit until you have veried that
voltage is not present. If you have to handle or touch the terminals or other control
panel components, use adequately insulated personal protection equipment and
tools.
After any maintenance and before re-connecting the power supply to the unit,
check that its enclosure is properly closed and that no items or tools were left
inside that could cause a short-circuit.
Do not disconnect the current transformer secondary without short-circuiting it
rst. The operation of a current transformer with an open secondary will cause an
overvoltage that could damage it and electrocute the person handling it.
3.2.- PREPARATION
The CIRCUTOR OPTIM P&P static capacitor banks come ready for easy installation and startup.
Remove the packaging of the unit and verify that its electrical features are suitable for connection to the available mains. To do so, check the features label located inside the cabinet next to
the FP regulator, see Figure 3.
Key data to be checked:
Mains frequency and voltage, Un / fn.
Nominal power of the capacitor bank, Qn (kvar) and composition
Current consumption, In . This current must be considered to select the proper size
of the power supply cable of the unit and ultimately the circuit breakers and protection
elements to be connected in front of it.

OPTIM P&P Series
3.3.- INSTALLATION LOCATION
It is important to maintain a minimum distance around the unit to facilitate cooling.
In self-supporting cabinets, the back and front sides of the cabinet must be kept at least 50 cm
away from walls of other units and other infrastructure to allow for ventilation.
In terms of the side walls, it is recommended that a separation of 10 cm be maintained between
adjacent cabinets.
On wall-mounted cabinets, it is recommended that at least 20 cm of separation be maintained
between the sides of adjacent cabinets.
Make sure the unit can be accessed easily.
The environmental conditions of the location where the unit is installed must not exceed the
limits set forth in the technical features (See “6.- TECHNICAL FEATURES”)
To ensure proper ventilation, the unit must be installed in a vertical position.
In accordance with the LVR, once the unit is installed, it must be protected against direct and indirect contacts; therefore, a circuit breaker and earth leakage protection for the capacitor bank
power supply line should be installed.
3.4.-CONNECTION OF THE CAPACITOR BANK TO THE MAINS
Check that the rated voltage of the capacitor bank matches the voltage between
phases of the network to which it is being connected.
Also check the operating circuit voltage (contactors).
( See “3.7.- AUXILIARY CONTROL VOLTAGE”)
For feeding cables into the capacitor bank cabinet, always and only use the cable
entry points available for this purpose.
There is a cable entry point on the bottom (base of the cabinet) in all the models
and also an entry point on the side in some models.
If another part of the cabinet is cut out to be used for cable entry, the CIRCUTOR manufacturer's guarantee shall be rendered void.
10
Do not cut holes in other parts of the cabinet for feeding cables through or for
installing support brackets.
It may produce trimmings that can cause short-circuits.
Instruction Manual
OPTIM P&P Series
3.5.-POWER CIRCUIT
Connect input terminals L1, L2 and L3 (power circuit) to the mains using proper sized cable in
accordance with the LVR, ITC-BT-19.
Generally, the cables of the phases adhere to the following colour code: L1 (black), L2 (brown),
L3 (grey).
If auxiliary voltage is required, the neutral cable will be connected to N (blue colour)
In order to determine the size of the phase cables, the nominal current In must be taken into
account, indicated on the unit label, and it should be able to withstand an overload in transients
of 1.5 times In. The neutral cable will be a minimum of 1.5 mm2.
3.6.- EXTERNAL CIRCUIT BREAKER AND PROTECTION ELEMENTS
If the capacitor bank does not have an internal switch or isolation switch, it must be connected
to a line that has an external switch or isolation switch.
The protection elements, isolation switches and/or switches that are added externally to the capacitor bank must be of a minimum size to withstand a current 1.5
times greater than what is indicated on the label (LVR, ICT-BT-48)
If an earth leakage protection for the capacitor bank is installed, its sensitivity and
trip delay must be adjustable.
When the capacitor bank is connected to the mains, it is recommended that the current
transformer (CT) is placed on the phase going to L1 (black cable).
Outputs S1 and S2 of the CT must be connected to the terminals with the same name.
3.7.- AUXILIARY CONTROL VOLTAGE
Control circuits are dened as those related with regulator output relays and the capacitor's
operating contactors. These circuits are usually powered with an auxiliary voltage of 230 V
~ (the most common case) or other voltages such as 110 V ~ (frequently for 500 V or 690 V
capacitor banks).
There are two possible ways of powering the circuit:

Instruction Manual
OPTIM P&P Series
3.8.- EARTH CABLE CONNECTION
Connect the earth cable to the capacitor bank's earth terminal located on the operating panel
of the unit.
The earth cable cross-section will be selected in accordance with the admissible current limits
established in the LVR (ITC-BT-19 – Internal or receiver installations) for each type of cable and
their location.
3.9.- CURRENT TRANSFORMER (CT) CONNECTION
A current transformer (CT) that is external to the capacitor bank must be
installed to measure the total load current plus that of the capacitor bank
(Figure 6).
The standard transformer must have a nominal output of 5 A at the secondary.
We recommend connecting the CT to phase L1 in the direction of the current ow
from P1 to P2 (see Figure 6) and connecting the secondary (terminals S1, S2) to
the terminals with the same name on the capacitor bank (see Figure 6)
Avoid current ow through the CT primary winding prior to connecting it to terminals S1 S2 of the bank.
If the CT must be installed while the installation is under load, short-circuit S1 and
S2 while they are not connected to the capacitor bank.
The current value of the CT primary winding must be equal to or slightly greater than the size of
the mains switch of the installation. Therefore, the CT must be able to measure the maximum
current expected to be consumed by all the loads being compensated.
Figure 6: Installation of the external current transformer (CT).
The connection point of the CT for a capacitor bank that compensates an entire installation is
after the mains switch of the installation.
To prevent excessive attenuation of the signal, it is recommended that the minimum cross-section of the secondary section winding cable (terminals S1, S2) is at least 2.5 mm2.

Once the cables are installed, disconnect the jumper connecting the S1 and S2 terminals or the
yellow jumper according to the terminals of the capacitor bank (Figure 8)
Figure 8: Jumper for short-circuiting the secondary winding of the current transformer (CT).
Any time you wish to change or disconnect a current transformer that is already
installed, it is important to install the jumper connecting S1 and S2.

OPTIM P&P Series
4.- CAPACITOR BANK START-UP
4.1.- BEFORE START-UP
The automatic capacitor banks include a power factor regulator.
The operation of said regulator must be known prior to start-up; for this reason, all
the capacitor banks include a specic manual for the regulator used.
Ensure you have this manual available for the start-up process.
In order to adjust the regulator incorporated to the capacitor bank and for optimum start-up, the installation load must be at least 30% or 40% of the nominal
load for which the capacitor bank has been dimensioned. If all the stages are not
included, they can be manually connected to check them all.
During low load periods, the entire capacitor bank should not be connected manually, as in some cases resonance with the power transformer of the installation
could occur.
The capacitors are connected in manual mode, rst allow enough time for the capacitors to discharge (as indicated in the capacitor bank's features label) before
reconnecting them to the network.
Otherwise, they could start-up out of phase with a voltage of up to 2xUn causing
the destruction of the capacitor.
4.2.- START-UP
Apply the safety regulations listed in section “3.- INSTALLATION” of this manual
before operating the units.
The National Electric Code of the country where the capacitor bank is installed or operated should be strictly followed.
1.- Ensure that the inner circuit breaker that starts the regulator (Figure 11) is connected.
2.- Connect the power supply to the panel and check that the regulator display illuminates im-
mediately. Otherwise, stop and check the previous step.
3.- Check the regulator's cos φ indication.
If the indication is out of range 0.5 to 1, it may be possible that the current transformer and/or
the power supply to the regulator are not properly connected.
Most of the regulators use only one current transformer. In this case, connect according to
Figure 10 (place the current transformer on phase L1 and take the power supply voltage from
phases L2 and L3).

the installation you are attempting to compensate. For this, follow the instructions on the manual of the regulator, included with the capacitor bank.
Instruction Manual
OPTIM P&P Series
4.3.- CHECKS ONCE THE CAPACITOR BANK HAS BEEN CONNECTED AND THE REGULATOR
1.- After start-up, make sure that the unit is operating correctly. A sign of proper operation is the
display indicating a cos φ close to 1 and the reactive energy meter should stop (if it is electromechanical) or the blinking light of the indicator LED of the kvar.h/pulse ratio should reduce its
rate.
2.- Check that the power supply voltage does not exceed the nominal value +10%
(IEC 60831-1).
3.- Check the current absorbed by each capacitor.
Under normal conditions, it must be close to the nominal value indicated on its dataplate and
never exceed 1.3 times this value constantly.
Continuous consumption over the nominal value may be caused by the presence of harmonics
in the network or an excessively high power supply voltage. Both circumstances are harmful
for capacitors.
4.- In accordance with the IEC 60831-1 Standard, the capacitor is prepared to operate at the
permanent voltage assigned to it and with an overvoltage of up to 10% for 8 out of every 24
hours.
Check the working temperature of the capacitors after they have been operating
for 24 hours.
The housing must be below 40 ºC.
