Congratulations for choosing VACON® NX Non-Regenerative Front End!
The User's Manual will provide you with the necessary information about the installation, commissioning and operation of VACON® NX Non-Regenerative Front End. We recommend that you carefully study these instructions before powering up the Non-Regenerative Front End for the first time.
In the Non-Regenerative Front End Application Manual you will find information about the Nonregenerative Front End application. Should that application not meet the requirements of your process, please contact the manufacturer for information on special application.
This manual is available in both paper and electronic editions. We recommend you to use the electronic version if possible. If you have the electronic version at your disposal, you will be able to benefit from the following features:
The manual contains several links and cross-references to other locations in the manual, which makes it easier to move around in the manual. The reader can thus easily find and check things.
The manual also contains hyperlinks to web pages. To visit these web pages through the links, you must have an internet browser installed on your computer.
This manual is applicable only for Non-Regenerative Front End unit, AC choke and optional components that are introduced in this manual.

1.SAFETY
ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT
THE ELECTRICAL INSTALLATION
1.1Warnings
1 |
The components of the power unit circuit are live when the Non- |
|
Regenerative Front End is connected to AC supply. Coming into contact |
|
with this voltage is extremely dangerous and may cause death or severe |
|
injury. The control unit is isolated from mains potential. |
2 |
The control I/O-terminals are isolated from the mains potential. Howev- |
er, the relay outputs and other I/O-terminals may have dangerous control |
!voltage present even when the Non-Regenerative Front End is disconnected from the AC supply.
WARNING |
3 |
Do not touch the components on the circuit boards. Static voltage dis- |
|
|
charge may damage the components. |
1.2Safety Instructions
1The Non-Regenerative Front End, AC choke and optional components are meant for fixed installations only.
2Do not perform any measurements when the Non-Regenerative Front End is connected to the AC supply.
3After having disconnected the Non-Regenerative Front End from the AC supply, wait until the fan stops. Wait 5 more minutes before doing any work on the Non-Regenerative Front End connections. Do not even open the cover before this time has expired.
4Do not perform any voltage withstand tests on any part of the NonRegenerative Front End. There is a certain procedure according to which the tests must be performed. Ignoring this procedure may result in damaged product.
5Before connecting the Non-Regenerative Front End to AC supply, make sure that the Non-Regenerative Front End front and cable covers are closed.
6
Before doing any work on Common DC bus, system must be grounded.
1.3Grounding
The Non-Regenerative Front End unit and AC choke must always be grounded with an grounding conductor connected to the grounding terminal.

2.EU DIRECTIVE
2.1CE marking
The CE marking on the product guarantees the free movement of the product within the EEA (European Economic Area). It also guarantees that the product complies with applicable directives (for example, the EMC directive and other possible so-called new method directives). VACON® NX NonRegenerative Front End carries the CE label as a proof of compliance with the Low Voltage Directive (LVD) and the Electro Magnetic Compatibility (EMC) directive. SGS FIMKO has acted as the Notified Body.
2.2EMC directive
2.2.1Introduction
The EMC Directive provides that the electrical apparatus must not excessively disturb the environment it is used in, and, on the other hand, it must have an adequate level of immunity toward other disturbances from the same environment.
The compliance of VACON® NX Non-Regenerative Front End with the EMC directive is verified with Technical Construction Files (TCF) and checked and approved by SGS FIMKO, which is a Notified Body. The Technical Construction Files are used to authenticate the conformity of VACON® NX NonRegenerative Front End with the Directive because it is impossible to test such a large product family in a laboratory environment and because the combinations of installation vary greatly.
2.2.2Technical criteria
Our basic idea was to develop a range of VACON® NX Non-Regenerative Front End offering the best possible usability and cost efficiency. EMC compliance was a major consideration from the outset of the design.
2.2.3VACON® Non-Regenerative Front End EMC classification
Factory delivered VACON® NX Non-Regenerative Front End are Class T equipment, which fulfills all EMC immunity requirements (standard EN 61800-3).
Class T:
Class T equipment have a small earth leaking current and can be used with floating DC input.
Warning: This product is of the restricted sales distribution class according to IEC 61800-3. In residential areas, this product may cause radio interference in which case the user may be required to take adequate measures.
2.2.4
The following page presents the photocopy of the Manufacturer's Declaration of Conformity assuring the compliance of VACON® NX Non-Regenerative Front End with the EMC-directives.

3.RECEIPT OF DELIVERY
VACON® NX Non-Regenerative Front End has undergone scrupulous tests and quality checks at the factory before they are delivered to the customer. However, after unpacking the product, check that no signs of transportation damage are to be found on the product and that the delivery is complete (compare the type designation of the product to the codes below, see Figure 3-1 and Figure 3-2).
Should the product have been damaged during the shipping, please contact primarily the cargo insurance company or the carrier.
If the delivery does not correspond to your order, contact the supplier immediately.
3.1Type designation code for the NFE unit
In VACON® type designation code for Common DC Bus components, the Non-Regenerative Front End Unit is characterized by letter N and letter N or S. If the Non-Regenerative Front End unit is ordered by letter N delivery is not include anything else than the unit itself. If letter S is used delivery include the unit, the AC choke.
NOTE! Delivery does NOT include any auxiliary devices which are needed for proper operation (the AC or DC fuses, the fuses bases, the main contactor or circuit breaker etc.) The customer must take care of them.

3.2Type designation code for the AC choke
AC choke has one version which is suitable for 380-500V and 525-690V voltages.
Figure 3-2. Type designation code for the AC choke.
3.3Storage
If VACON® NX Non-Regenerative Front End is to be stored before use, make sure that the ambient conditions are acceptable:
Storage temperature |
°C |
Relative humidity |
<95%, no condensation |
3.4Maintenance
All technical devices, drives as well, need a certain amount of care-taking and failure preventive maintenance. To maintain trouble-free operation of the VACON® NX Non-Regenerative Front End, environmental conditions, as well as load, line power, process control, etc. have to be within specifications, determined by manufacturer.
If all conditions are in accordance with the manufacturer's specifications, there are no other concerns, but to provide a cooling capacity high enough for the powerand control circuits. This requirement can be met by making sure, that the cooling system works properly. Operation of cooling fans and cleanness of the heat sink should be verified regularly.
Regular maintenance is recommended to ensure trouble free operation and long lifetime of VACON® NX Non-Regenerative Front End. At least the following things should be included in the regular maintenance.

Non-Regenerative Front End (NFE) |
4.NON-REGENERATIVE FRONT END (NFE)
4.1Introduction
The VACON® NX Non-Regenerative Front End is used to transfer power between the AC input and intermediate DC circuit. The VACON® NX Non-Regenerative Front End has only a one-way function. This means that power can only be transferred from the AC input to the intermediate DC circuit. If braking is needed, brake chopper has to be connected to the intermediate DC circuit.
In a typical VACON® NX Non-Regenerative Front End configuration, the desired number of Inverters, Figure 4-1, are connected to the intermediate DC circuit.
The Non-Regenerative Front End configuration consists of the unit itself, AC choke, AC fuses, main contactor and DC fuses, Figure 4-2.
