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 installation of the unit may result in injury to personnel as well as damage to equipment. In particular, 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 maintenance instructions for the equipment throughout its working life. In particular, follow the installation standards indicated in the Low Voltage regulations and additional technical instructions.

The installation, operation and maintenance of LV equipment must only be carried out by authorised installers. See the National Code Instructions specifically defining the requirements that authorised installers must meet in each country.

If in order to install the equipment, you must work in areas that have high-voltage (HV) equipment installed, then the personnel handling equipment in this area must be authorised to work in HV installations. Refer to the National Code Instructions, in each country, which specifically regulate the requirements for personnel and maintenance companies autorised to handle high-voltage installations.

INTRODUCTION

The purpose of this manual is to assist during the installation, start-up and maintenance of EMKseries low-voltage (LV) capacitor banks with static switching. Carefully read the manual to achieve the best equipment performance.

SAFETY HAZARDS AND WARNINGS

2.1 Hazards encountered during the installation and start-up of electrical equipment.

Do not access the active elements of a capacitor bank with static switching that has been previously powered, since it might have residual voltages at the capacitors. 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 verified that there is no residual voltage at the capacitors. If you have to handle or touch the terminals or other control panel components while the equipment is connected to the supply, use adequately insulated personal protection equipment and tools.

After maintenance and before re-applying 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 open the secondary circuit of current transformer without short-circuiting it first. The operation of a current transformer with an open secondary will cause an overvoltage that can damage it and electrocute the person handling it.

2.2 Safety warnings

Apart from the general operational rules, the standards and applicable laws of the country where the capacitor bank is installed or operated should be strictly 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 purposes.

Connecting the equipment to the public grid will be carried out in compliance with standard EN-IEC60204-1, on the safety of LV electrical installations.

It is recommended that several personnel are present when handling the equipment for either installation or maintenance.

If damage or faults are detected during equipment operation, or in circumstances that compromise safety, immediately stop work in that area and disconnect the equipment in order to check it while it is de-energized.

Modifying, upgrading or rebuilding the equipment without written authorization from the manufacturer is prohibited.

RECEPTION, TRANSPORT, HANDLING AND STORAGE

3.1 Reception protocol

 Make sure that the equipment has not been damaged during transport.

Instructions Manual M98118701-01-12A 4

EMK

series

 Check that the equipment received matches the order and that its electrical features 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 package.

 Unload and transport the equipment in accordance with the instructions in section 3.2  Perform an external and internal visual inspection of the equipment prior to connecting it.  Check that all items on the packing list are present.

If any discrepancy is noticed upon reception, immediately contact the transport company or CIRCUTOR's after-sales services.

3.2 Transport, loading and unloading, handling and storage

The transport, loading and unloading and handling of the equipment must be carried out with proper precautions and using the proper manual or mechanical tools to prevent damaging the equipment.

If the equipment is not to be immediately installed, it must be stored at a location with a firm and level floor and the storage conditions listed in the technical features section must be observed. In this case, it is recommended that the equipment be stored with its original protective packaging.

To move the equipment a short distance, the unit's base support profiles facilitate handling with a pallet jack or forklift.

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 equipment be securely fastened and that no abrupt operations are made. The equipment should not be lifted more than 20 cm over the ground.

Fig. 3-1 .-Transport with pallet jack

When unloading and moving the equipment, 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. The cabinet must be raised by placing the forks underneath the profile that supports the equipment. (Fig. 3-2).

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 equipment. The necessary precautions must be taken to prevent the equipment from tipping over during abrupt operations.

3.3 Storage

The following storage recommendations shall be followed for the static capacitor banks:

- Avoid placing it on uneven surfaces.

- Do not store in outdoor areas, humid areas or areas exposed to the splashing of water.

- Avoid hot spots (maximum environmental temperature: 45 ºC)

- Avoid saline and corrosive environments.

- Avoid storing the equipment 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 equipment cabinets.
