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 authorised installers. LV regulations (Art. 22) specifically
define the requirements that authorised installers must meet.
Do not access the active parts 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 panel, use adequately insulated personal protection
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 that is handling it.
2.2 Safety warnings
Apart from the general standards listed above, 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.
Connecting the equipment to 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 equipment operation, or in circumstances
that may 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.
