SAFETY SAFETY ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT THE ELECTRICAL INSTALLATION 1.1 Warnings 1 2 3 4 WARNING 5 6 7 8 9 1.2 The NX frequency converter is meant for fixed installations only. Do not perform any measurements when the frequency converter is connected to the mains. Do not perform any voltage withstand tests on any part of NX. There is a certain procedure according to which the tests shall be performed. Ignoring this procedure may result in damaged product.
SAFETY 1.3 7(110) Earthing and earth fault protection The NX frequency converter must always be earthed with an earthing conductor connected to the earthing terminal . The earth leakage current of NX frequency converters exceeds 3.5mA AC. According to EN61800-5-1, one or more of the following conditions for the associated protective circuit shall be satisfied: a. The protective conductor shall have a cross-sectional area of at least 10 mm2 Cu or 16 mm2 Al, through its total run. b.
2 8(110) EU DIRECTIVE 2. EU DIRECTIVE 2.1 CE marking The CE marking on the product guarantees the free movement of the product within the EEA (European Economic Area). NX frequency converters carry the CE label as a proof of compliance with the Low Voltage Directive (LVD) and the Electro Magnetic Compatibility (EMC). The company SGS FIMKO has acted as the Competent Body. 2.2 2.2.
EU DIRECTIVE 9(110) Class T: Frequency converters of this class fulfil the product standard EN 61800-3 (2004) if intended to be used in IT systems. In IT systems, the networks are isolated from earth, or connected to earth through high impedance to achieve a low leakage current. NOTE: if converters are used with other supplies, no EMC requirements are complied with. Class N: The drives of this class do not provide EMC emission protection. These kinds of drives are mounted in enclosures.

4 16(110) TECHNICAL DATA 4. TECHNICAL DATA 4.1 Introduction Figure 4-1 presents the block diagram of the NX frequency converter. The frequency converter mechanically consists of two units, the Power Unit and the Control Unit. Pictures of the mechanical assemblage on pages 54 to 62. The three-phase AC-choke (1) at the mains end together with the DC-link capacitor (2) form an LC-filter, which, again, together with the diode bridge produce the DC-voltage supply to the IGBT Inverter Bridge (3) block.
TECHNICAL DATA 17(110) The control keypad constitutes a link between the user and the frequency converter. The control keypad is used for parameter setting, reading status data and giving control commands. It is detachable and can be operated externally and connected via a cable to the frequency converter. Instead of the control keypad, also a PC can be used to control the frequency converter if connected through a similar cable.

INSTALLATION 5. INSTALLATION 5.1 Mounting 25(110) The frequency converter can be mounted in either vertical or horizontal position on the wall or on the back plane of a cubicle. However, if the drive is mounted in a horizontal position, it is not protected against vertically falling drops of water. Enough space shall be reserved around the frequency converter in order to ensure a sufficient cooling, see Figure 5-11, Table 5-10 and Table 5-11. Also see to that the mounting plane is relatively even.
