Important Information
Do not attempt to install, operate, maintain or inspect power quality filters until you have read through the safety
notes and installation guidelines as well as installation manual and product specification. Do not use any LS
Electric product until you have a full knowledge of the equipment, safety notes and installation guidelines.
General Installation Notes
▪
Please read and follow the safety and application notes below.
▪
Carefully inspect the shipping container and the product prior to the installation. In case of visual
damage, do not install the filter and file a claim with the freight carrier involved.
▪
Filters may be heavy. Follow the instructions for lifting heavy equipment defined by your company.
▪
Use an appropriately sized threaded bolt for every mounting hole/spot provided by the filter flange.
The strength class of the bolt must be determined by the installer, depending upon filter weight and
the material of the mounting surface.
▪
Connect the filter to the protective earth(PE) terminal(s).
▪
Remove all line side power, then connect the phase terminal(s). The filter label may also indicate
LINE (grid side terminals) and LOAD (power electric terminals)
▪
For the electrical connection of the filter terminals, apply the torque recommended on the filter label
and/or in the published filter datasheets
▪
Cable or busbar cross sections have to be chosen in accordance with national and international
electric codes and applicable product standards governing the equipment that will incorporate the
power quality filters and the equipment in use.
▪
Filters provide additional terminal, e.g. for over-temperature monitoring. These features have to be
properly used before energizing the filter. If uncertain, please consult your local LS Electric
representative.

Equipment installation, start-up, operation and maintenance (if any) have to be carried out by a
trained and certified electrician or technician who is familiar with safety procedures in electrical
systems. Non-qualified persons are not allowed to use, install, operate or maintain PQ filters.
▪
High voltage potentials are involved in the operation of power quality equipment. Always remove
power supply before handling energized parts of the filter, and let ample time elapse for the capacitors
to discharge to safe levels (<42V). Residual voltages are to be measured both line to line and line to
earth.
▪
Correct protective earth of the equipment must be established and the user must be protected against
supply voltage in accordance with applicable national and local regulations. Always practice the
safety procedures defined by your company and by applicable local electric codes when handling,
