Original Instruction Manual: EPA EMC RFI Filters
Warnings and safety instructions
Before installing and commissioning the RFI Filters, you must read all warnings and safety instructions (
/
/ ) carefully. This also applies to the warning signs
attached to the RFI Filters. Please ensure that the signs are not removed or legibility is impaired by external influences.
Death, severe physical injury or substantial damage to property may occur, if the required prevention measures are not taken and attention to the notes in the
text is not paid respectively.
Intended use
The RFI Filter reduces line-conducted, electromagnetic interferences and improves the EMC characteristics of the devices next in line. It is part of the standards
conformity and a prerequisite of the CE mark.
RFI Filters may be used only for the intended use within the specified values in low voltage networks, in accordance with the given notes in the data sheets and
the catalogue. The conditions at site must match all the information on the set filter.
Unless otherwise stated RFI Filters are not designed for operation in IT networks. Because of safety reasons special IT Filters are required therefore.
Safety instructions
RFI Filter planning, mounting, installation, set-up, maintenance, and repair must be carried out by a qualified person who is familiar with the
requirements for safety in electrical installations. Relevant documents have to be made available to these persons.
Attention, danger of Life!
Improper contact with the in- or output terminals or the connecting cables may cause electric shock! The RFI Filter must not be opened, disassem-
bled or reconstructed! Any other use other than here described is not permissible and can lead to hazards such as short circuits, fire damage, etc.!
RFI Filters may cause leakage currents to earth. Always connect the filter to protective earth first, then continue with the wiring of phase/neutral
terminals. When decommissioning the filter, remove the PE connection last. Depending on the amount of leakage current, the special instructions
on the implementation of the protective earth connection must be observed.
RFI Filters are equipped with capacitors, so that after disconnection from the network potentially hazardous voltages may still be present. After
disconnection from the network it is necessary to wait until the capacitors have been fully discharged by the internal resistors. A waiting time of at
least 10 minutes has to be observed!
Overloading of the RFI Filter, such as by resonant circuits and higher frequency voltage stress, can lead to severe physical injury and death as
well as substantial property damage (e.g. by the bursting of the filter housing).
RFI Filters are lossy electrical components. Filter surfaces and terminals may get hot under full load operating conditions.
Any damage caused by failure to observe the instruction manual voids the warranty. No liability will be accepted for consequential damage.
Likewise, no warranty is given if damage to property or personal injury is caused by improper use or not following the safety instructions. All such
warranty claims will be void.
After unpacking and before installation, each RFI filter must be checked for signs of mechanical damage.
RFI Filters must be protected in the application by appropriate overcurrent protective devices against inadmissible exceeding of the rated currents.
Technical data
Before using the RFI Filter make sure you read the data sheet. If this is not available, it can be downloaded online under www.epa.de, respectively provided by EPA GmbH.
Here, important information on input voltage, rated current and ambient temperature are listed. The RFI Filter must not be operated outside the stated technical specifications!
Installation and set-up
Only a qualified technician is allowed to install this unit. During installation the respective standards regarding electrical safety have to be observed. Cut off
mains power before installation.
It is recommended to use the shortest possible lines between RFI Filter and load. The input and output lines must not be placed together.
The RFI Filter is built in accordance with Protection Class 1. With the electrical connection it is important to make sure that the protective earth is connected
first. Ensure that during installation of the RFI Filter the protective conductor connection is properly attached to the filter, otherwise there may be excessively
high touch voltages on metallic filter housing. When installing the RFI Filter make sure that heating by neighbouring electrical equipment is avoided.
Mounting may only be done on the intended fastening points. Footprint filters for variable frequency drives are made to carry the specified VFD mounted on
the top of the filter. Ensure a good and low-resistance contact when mounting. The specifications of the required tightening torques are to be considered.
In practice, different results may be achieved, especially if the generally accepted rules of EMC for mounting of RFI Filters and routing of power and control
cables are not or only insufficiently respected.
Operation
RFI Filters may only be operated within the specifications given by the current data sheet. This applies especially for input voltage, rated current and ambient
temperature. In case ambient temperatures higher than the specified ones occur during operation, the RFI Filter may only be operated with a reduced operat-
ing current (derating). More information is available in our current RFI Filter catalogue.
Leakage currents
By using the RFI Filter, operational leakage currents to earth are generated. Thus it may trigger upstream protective devices (residual current circuit breakers),
particularly when there are unbalanced supply voltages or mains phase failure. Also not simultaneously switching relays and contactors can result in momen-
tary higher leakage currents in three-phase systems. This can be counteracted with appropriate filters.
Maintenance
RFI Filters are maintenance-free. In case of failure, the EMC filter is to be disconnected from the mains. A review of function and electrical safety is only possible
at the manufacturer.
Disposal
Electrical and electronic devices must not be disposed in the garbage! Dispose product at it’s life-end according to the local regulations.
