User and Installation Manual Ecosine Max Passive Harmonic Filters 4/66
i. General Safety Notes and Installation Guidelines
(Cautions and Warnings)
Important Information
These general safety notes refer to the group of power quality filters including
active and passive harmonic filter (AHF, PHF), AC line chokes and output filters.
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 Schaffner product
until you have a full knowledge of the equipment, safety notes and installation
guidelines. The same applies to all warnings placed on the filters. Please ensure
that those are not removed and their legibility is not influenced by external
factors.
The following symbols, terms and designations are used in these general safety
notes and installation guidelines:
Follow these instructions to avoid hazardous
conditions which could cause minor or
moderate injury or may cause damages to the
unit.
Follow these instructions to avoid hazardous
conditions which could result in death or
serious injury.

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, 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. The filter label may also
indicate LINE (grid side terminals) and LOAD (power electronics
terminals).
▪For the electrical connection of the filter terminals, apply the
torques 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.
▪Some filters provide additional terminals, e.g. for over-
temperature monitoring. These features have to be properly used
before energizing the filter. If uncertain, please consult your local
Schaffner representative.
▪Active Harmonic Filters (AHF) are working with current
transformers (CTs which are a 3rd party product and which are
typically installed in electrical equipment with lethal high voltage
levels. Before attempting to install CTs read the CT installation
safety page provided by the CT manufacturer. Always consider
transformer as a part of the circuit to which it is connected, and do
not touch the leads and terminals or other parts of the transformer
unless they are known to be grounded.
▪In order to get the maximum benefit out of your power quality filter,
please also consult aditional user manuals, installation manuals,
whitepaper and other material, published in the download section
of www.schaffner.com. These additional guidelines provide
helpful hints for equipment related topics as well as technical
knowledge.
Safety Notes and Regulations
1. Label on equipment
2. Safety note category
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 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 earthing 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 national
electric codes when handling, installing,
operating or maintaining electrical equipment.
Some product may include EMC filters which
may cause leakage currents to ground. Always
connect the filter to protective earth (PE) first,
then continue with the wiring of phase/neutral
terminals. When decommissioning the filter,
remove the PE connection at the end.
Using the direct OFF setting in AHF does not
disconnect the equipment from mains and is
thus not to be used as a safety switch.
Follow the general installation and
environmental condition notes closely. Ensure
that cooling slots (if any) are free from
obstructions that could inhibit efficient air
circulation. Operate the filter within its
electrical, mechanical, thermal and ambient
specifications at all times.
Power quality filters are lossy electrical
components. Parts/surfaces of the equipment
may get hot under load operating conditions.
At altitudes above 2000m, please contact
Schaffner prior to installation.
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.
In case of uncertainty and questions please
contact your local Schaffner partner for
assistance (details per region available at
www.schaffner.com).
