When unloading and moving the unit, use a forklift with forks long enough to support the entire
length of the base. Otherwise, the forks should be long enough to support at least ¾ of said
depth. The forks must be at and supported rmly by the base. Raise the cabinet by placing the
forks underneath the prole that supports the unit. (Figure 2).
There might be an offset in the centre of gravity from the centre of the cabinet,
as a result of the uneven distribution of loads inside the unit. The necessary
precautions must be taken to prevent the unit from tipping over during abrupt
operations.
Figure 2: Unloading with a forklift.
1.3.- STORAGE
The following storage recommendations must be followed for the hybrid capacitor banks:
Avoid placing them on uneven surfaces.
Do not store them in outdoor areas, humid areas or areas exposed to splashing
water.
Avoid hot spots (maximum ambient temperature: 40 ºC)
Avoid salty and corrosive environments.
Avoid storing the units in areas where a lot of dust is generated or where the risk of
chemical or other types of contamination is present.

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.
Auxiliary control voltage, U

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.

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:
