1.- VERIFICATION UPON RECEPTION
1.1.- RECEPTION PROTOCOL
Check the following points when you receive the unit:
a) The unit meets the specications described in your order.
b) The unit has not suffered any damage during transport.
c) Perform an external visual inspection of the unit prior to switching it on.
d) Check that it has been delivered with the following:
- The unit manual
- The regulator installation guide.
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 unit must be carried
out with proper precautions and using the proper manual and mechanical
tools so as not to damage it.
If the unit is not to be immediately installed, it must be stored at a location
with a rm and level oor, and the storage conditions listed in the technical
features section must be observed. In this case, it is recommended that the
unit be stored with its original protective packaging.
To move the unit a short distance, the unit's oor support proles facilitate handling with a pallet
jack or forklift. (Figure 1)
Figure 1: Transport with pallet jack.
The centre of gravity of some units may be found at a considerable height.
Therefore, when handling with a forklift, it is recommended that the unit be
securely fastened and that no abrupt manoeuvres made. The unit should not
be lifted more than 20 cm off the ground
6
OPTIM EMS-C series
Instruction Manual
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 shall be followed for the static 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.
Do not place any weight on top of the unit cabinets.

2.- PRODUCT DESCRIPTION
The purpose of this manual is to assist during the installation, start-up and maintenance of
OPTIM EM-C series low voltage (LV) capacitor banks with static switching operation. Carefully
read the manual to achieve the best performance from said units.
2.1.- CAPACITOR BANK COMPONENTS
From the electrical standpoint, the unit is made up of the following blocks:
2.1.1. FAST REGULATOR
The static capacitor banks are equipped with Computer Max 6f V12dc fast regulators, which
have static outputs, that is, instead of an output via relay contact, these regulators have a sem-
iconductor-based switch, which enables them to perform operations in fast succession and in
practically every network cycle.
These outputs provide a 12 Vdc activation signal to the + and - inputs of the connection control-
ler boards, as opposed to the CPC4 type zero voltage.
Fast regulators enable regulation with minimum delay, generally between 20 and 100 ms (See
the manual or quick guide of the specic regulator being used)
2.1.2. CPC4 BOARD: ZERO SWITCHING STEP CONNECTION CONTROL
The static capacitor banks come equipped with CP4 boards.
The role of the CPC panel is to control the zero switching step connection of the thyristor-diode
modules, and so avoid connection current transients.
The standard connection diagram of a step can be seen in Figure 3 and with more detail in
section “7.- OPTIM EMS-C TYPE DIAGRAM”.
The CPC panels are activated via a 12 Vdc signal supplied by the 6f V12dc Computer Max
regulator outputs. The standard CPC4 is ready for Umax = 440 V mains.

2.1.3. POWER BLOCK
The power block of an OPTIM EMS-C unit consists of 2 to 4 groups of thyristor-diode semicon-
ductors + three-phase capacitor + three-pole circuit breaker.
Each group is composed of a cylindrical capacitor with 3 terminals, 2 thyristor-diode modules
attached to a general heatsink and suitable protection elements for the module power (three-
pole circuit breaker).

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 vari-
ous 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
damages resulting from the use of non-original products or accessories or those made by other
manufactures.
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.
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 af-
ter the power supply has been disconnected.
