CIRCUTOR OPTIM-FR Series - Manual (Page 4)

Instruction Manual 2
1 INTRODUCTION
The purpose of this manual is to assist during the installation, start-up and maintenance of low
voltage (LV) capacitor banks with FR series detuned filters operated by means of 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 authorised installers. See CENELEC Low Voltage Directive
(LVD 2006/95/EC) and the technical instructions of the Electrical National Code in
each country to find the requirements that authorised installers must meet.
Do not access the active elements of a filter bank that has been powered, since
residual voltages might be present because of capacitors charge. 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
voltage is not present. If you have to handle or touch the terminals or other control
panel components, use adequately insulated personal protection gloves,
equipment and tools.
After maintenance and before re-applying power 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 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 standards listed above, the standards and applicable
regulations of the country where the filter 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 must 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.
2.3 Application warnings
Capacitor banks with detuned filters can attenuate the remote control signals
transmitted through the network which are used in some countries. When remote
control frequencies close to the tuning frequency of FR filters are used, blocking
filters must be placed in front or the tuning frequency of the FR filters must be
changed.
