Mounting and Installation Guidelines
INS 112882 C 05.03.2014 EJE 2I5
General application notes
NOTICE Filter suitability for a given application must ultimately be determined by the user
(the party that is putting the filter into operation) on a case-by-case basis.
Schaffner will not assume liability for any consequential downtimes or damages
resulting from use of filters outside their specifications.
NOTICE Sine wave filters must be mounted in a clean, dry location (enclosures, cabinets,
closed rooms). Contaminants such as oils, liquids, corrosive vapors, abrasive
debris, dust and aggressive gases must be kept out of the filter enclosure.
Standard products Standard catalog filters must be used for the published applications and
operated within the published technical specifications.
Custom products Custom filters must be used for the bespoke application and operated within the
provided and mutually agreed technical specifications.
NOTICE Sine wave filters are design-in products by definition. Their functionality and
suitability must be determined with a proper design-in process, involving
electrical, mechanical and thermal verification within the final equipment.
General installation notes
•Carefully inspect the shipping container and the product prior to the installation. In case of visual
damage, don’t 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/slot 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) and neutral terminal (if any) of the
filter.
•For the electrical connection of the filter terminals, apply the torques recommended on the filter label
and/or in the published filter datasheets. For the bus bar connections do apply the corresponding
tightening torque of the screws.
•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
filter.
•Special attention should be paid to cable dimensioning, fuses, grounding, shutdown, disconnection,
and overcurrent protection.
