OPTIM FRS/FR P&P series REVISION LOG Table 1: Revision log. Date Revision Description 10/15 M090B01-03-15A Initial Version Changes in the following sections: 03/16 M090B01-03-16A 3.9. Changes in the following sections: 04/16 M090B01-03-16B 3.9. Changes in the following sections: 11/19 M090B01-03-19A 3.2.
- The device manual - The installed regulator manual. If any problem is noticed upon reception, immediately contact the transport company and/or CIRCUTOR's after-sales service. 1.2.- TRANSPORT AND HANDLING The transport, loading and unloading and handling of the device must be car- ried out with proper precautions and using the proper manual and mechanical tools so as not to damage it.
OPTIM FRS/FR P&P series When unloading and moving the device, 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 flat and supported firmly by the base. Raise the cabinet by placing the forks underneath the profile that supports the device.
OPTIM FRS/FR P&P series 2.- PRODUCT DESCRIPTION The purpose of this manual is to assist during the installation, start-up and maintenance of OPTIM FRS/FR P&P series low voltage (LV) capacitor banks with detuned filters, switched by contactors. Carefully read the manual to get the best performance from these devices. 3.- INSTALLATION 3.1.- PRELIMINARY RECOMMENDATIONS In order to use the device safely, it is critical that individuals who handle it follow...
3.2.- PREPARATION The CIRCUTOR OPTIM FRS/FR P&P static capacitor banks come ready for easy installation and start-up. Remove the packaging of the device and verify that its electrical features are suitable for con- nection to the available mains.
OPTIM FRS/FR P&P series 3.3.- PLACE OF INSTALLATION It is important to maintain a minimum distance around the device 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 devices and structures to allow for ventilation.
OPTIM FRS/FR P&P series 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 grid to which it is being connected. Also check the operating circuit voltage (contactors). (See “3.7.- AUXILIARY CON- TROL VOLTAGE”...
OPTIM FRS/FR P&P series Figure 5: Cable entry points of the OPTIM FR P&P models. 3.5.-POWER CIRCUIT Connect input terminals L1, L2 and L3 (power circuit) to the mains using a cable with a suitable cross-section, in accordance with the LVR, ITC-BT-19. Generally, the phase cables are according to the following colour code: L1 (black), L2 (brown), L3 (grey).
OPTIM FRS/FR P&P series 3.7.- AUXILIARY CONTROL VOLTAGE Control circuits are defined as those related with regulator output relays and the capacitor's operating contactors. These circuits are usually powered with a 230 V~ auxiliary voltage (most common). For all the standard models of the OPTIM FRS P&P and OPTIM FR P&P range, the auxiliary voltage is supplied from an internal AUTOTRANSFORMER: Does not require connection of the external neutral.

To prevent excessive attenuation of the signal, it is recommended that the minimum cross-sec- tion of the secondary winding cable (terminals S1, S2) is at least 2.5 mm Figure 7: Current transformer (CT) connection terminals.

OPTIM FRS/FR 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 specific manual for the regulator used. Ensure you have this manual available for the start-up process.

OPTIM FRS/FR P&P series NOTE: For capacitor banks with filters, the capacitor's voltage exceeds the network voltage by a % that is approximately equal to the filter's overvoltage factor (p%). In fact, the capacitor's real overvoltage is: ∆ − 5.- To check the filter's correct tuning, make sure that the voltage on the terminals of each wind- ing of the reactor is: −...
OPTIM FRS/FR P&P series 5.- MAINTENANCE 5.1.- SAFETY REGULATIONS Before operating the devices, follow the safety regulations indicated in section “ ” of this manual 3.1.- PRELIMINARY RECOMMENDATIONS The National Electric Code of the country where the capacitor bank is installed or operated should be strictly followed.
OPTIM FRS/FR P&P series 5.2.2. KEY POINTS FOR INSPECTING CONTACTORS Check that the plastic parts are not blackened and do not show signs of burning or hardening. Check that the head is properly inserted. The terminals must be clean. If the capacitor bank includes RD discharge resistors, check that they are in good condition (they are not open and show no signs of burning).
OPTIM FRS/FR P&P series 5.2.4. KEY POINTS FOR INSPECTING THE REGULATOR Check that the regulator does not show signs of deterioration and the display is lit as normal. Inspect the cables and terminals. They should be clean and should not be hardened or over- heated.
