SYMBOLS AND WARNINGS
Pay attention to the warnings in this manual, which are shown with the following
symbols.
DANGER: Warns of a risk, which could result in personal injury or material
damage.
WARNING: Indicates that special attention should be paid to a specific point.
If you must handle the equipment for its installation, start-up or maintenance, the
following should be taken into consideration:
Incorrect handling or insta ll ation of the unit may result in injury to personne l as wel l
as damage to equipment. In par ticular, handling with power applied may result in
electric shock, which may cause death or serious injury to personnel. Defective
installation or maintenance may also lead to the risk of fire.
Carefully read the manual prior to connecting the equipment. Follow all the
installation and m aintenance i nstructions for the equipm ent throughout its work ing
life. In particular, follow the installation standards indicated in the Low Voltage
regulations and additional technical instructions.
The installation, operat ion and m aintenance of LV eq uipment m ust only be car ried
out by authorised installers. LV regulations (Art. 22) specifically define the
requirements that authorised installers must meet.
If in order to install t he equipment, you m ust work in areas that have high-voltage
(HV) equipment install ed, t hen the personnel handl ing equipment in this ar ea must
be authorised to work in HV installations. Refer to Royal Decree 55/2004 dated
18-06-2004, which regulates the requirements and the operation of high-voltage
installation and maintenance companies.

1 INTRODUCTION
The purpose of this manual is to assist during the installation, start-up and maintenance of low
voltage (LV) capacitor banks switched by contactors. Carefully read the manual to achieve the
best equipment performance.
2 SAFETY HAZARDS AND WARNINGS
2.1 Hazards encountered during the installation and start-up of electrical equipment.
The installation, operation and maintenance of low voltage (LV) equipment must
only be carried out by aut horised installers . LV regu lations ( Art. 22) s pecif ically
define the requirements that authorised installers must meet.
Do not access the active p arts of a capacitor bank that has power supply applied
until a minimum of 5 minutes has elapsed from the time the power was
disconnected.
Do not touch the terminals or active parts of the unit until you have verified that
voltage is not present. If you must handle or touch the terminals or other
components of the control pane l, use adequately insul ated personal protecti on
equipment and tools.
After maintenance and before re-applying power to the unit, check that its enclosure
is properly closed and tha t no item s or tools were lef t inside that cou ld cause a
short-circuit.
Do not disconnect the c urrent transform er secondary without s hort-circu iting it first.
The operat ion of a current transformer with an open sec ondary will cause an
overvoltage that can damage it and electrocute the person that is handling it.
2.2 Safety warnings
Apart from the genera l sta n dar ds lis ted abo ve, the s t an dar ds an d ap pl ic ab le laws of
the country where the capac itor bank is installed or oper ated should be strictl y
followed.
Installation or maintenance personnel should read and understand this manual
before operating the equipment.
A copy of this manual should always be available to maintenance personnel for
reference.
Connecting the equipment t o the public grid will be carried out in compliance with
standard EN-IEC60204-1, regarding the safety of LV electrical installations.
It is recommended that several personnel be present when manipulating the
equipment for its installation or maintenance.
If damage or faults are detected during equipm ent operation, or in circum stances
disconnect the equipment in order to check it while it is de-energized.
Modifying, upgrading , or re building t he equ ipm ent without writt en auth orizat ion fr om
the manufacturer is prohibited.

3 RECEPTION, TRANSPORT, HANDLING AND STORAGE
3.1 Reception protocol
Make sure that the unit has not been damaged during transport.
Check that the unit rec eived matches the order and that its electrical characteristics are
suitable for the grid where it is to be connected.
Check the shipping documentation. The dispatch note number must coincide with the
number marked on the outer part of the unit.
Unload and transport the unit in accordanc e with the ins t ruc tion lis ted in sect ion 3.2
Perform an external and in ternal visual inspect ion of the equipm ent prior to disconnect ing
it.
Check that all items on the packing list are present.

with a firm and level floor and the storage conditions listed in the technical
features section must be followed. In this case, it is recommended that the
equipment be stored with its original protective packaging.
Therefore, when hand ling with a fork lift, it is recommended th at the equipm ent
be securely fastened and that no abrupt manoeuvres are carried out. The

When unloading and m oving the equipment, use a fork lift with forks long enough to support the
entire length of the base. O therwise, the forks s hould be long enough to s upport at least ¾ of said
depth. The forks mus t be flat and must be laid firmly on the base. T he cabinet must be raised b y
placing the forks underneath the profile that supports the equipment. (Fig.3-2).

3.3 Storage
The following storage recommendations shall be followed for the capacitor bank:
- Avoid placing it over irregular surfaces.
- Do not store in outdoor areas, humid areas or areas exposed to projected water.
- Avoid hot spots (maximum environmental temperature: 45 ºC)
- Avoid saline and corrosive environments.
- Avoid s toring the equ ipment in areas where a lot of dust is ge nerated or where the risk of
chemical or other types of contamination is present.
- Do not place any weight on top of the equipment cabinets.
