However, after unpacking the product, check that no signs of transport damages are to be found on the product and that the delivery is complete (compare the type designation of the product to the code below, Figure 3-1.
Page 15: Storage
14(110) RECEIPT OF DELIVERY Storage If the frequency converter is to be kept in store before use make sure that the ambient conditions are acceptable: ° Storing temperature –40…+70 Relative humidity <95%, no condensation If the converter is to be stored during longer periods power should be connected to the converter once a year and kept on for at least 2 hours.
Page 16: Warranty
RECEIPT OF DELIVERY 15(110) Warranty Only manufacturing defects are covered by the warranty. The manufacturer assumes no responsibility for damages caused during or resulting from transport, receipt of the delivery, installation, commissioning or use. The manufacturer shall in no event and under no circumstances be held responsible for damages and failures resulting from misuse, wrong installation, unacceptable ambient temperature, dust, corrosive substances or operation outside the rated specifications.

16(110) TECHNICAL DATA TECHNICAL DATA Introduction Figure 4-1 presents the block diagram of the NX frequency converter. The frequency converter mechani- cally 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.
Page 18 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.
