SAFETY 1. vacon • 5 SAFETY ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT THE ELECTRICAL INSTALLATION 1.1 Warnings 1 2 3 4 5 6 7 8 9 1.2 The Vacon 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 Vacon NX. There is a certain procedure according to which the tests shall be performed. Ignoring this procedure may result in damaged product.
6 • vacon 1.3 SAFETY Earthing and earth fault protection The Vacon NX frequency converter must always be earthed with an earthing conductor connected to the PE bar in the lower front side of the cabinet. The earth fault protection inside the frequency converter protects only the converter itself against earth faults in the motor or the motor cable. It is not intended for personal safety.

The box may be transported either horizontally or vertically, while transportation of the cage in a horizontal position is not allowed. Always refer to shipping marks for more detailed information. To lift the unit out of the box, use lifting equipment capable of handling the weight of the cabinet.
MOUNTING 5.3.1 vacon • 23 Fixing to the floor and to the wall In installations where the cabinet is mounted against the wall, it is more convenient to fix the top of the cabinet to the wall. Fix the cabinet in the two front corners to the floor with bolts. Fix the top part to the wall with bolts. Note that the rails and the fixing lugs can be moved horizontally to make sure the cabinet stands in a horizontal position.
24 • vacon 5.4 MOUNTING AC choke connections Note: The NXC regenerative low-harmonic drive incorporates an LCL filter instead of AC chokes and this instruction can be ignored. The AC input choke carries out several functions in the Vacon NX 6- and 12-pulse frequency converter. The input choke is needed as an essential component for motor control, to protect the input and DC-link components against abrupt changes of current and voltage as well as to function as a protection against harmonics.
MOUNTING 5.5 vacon • 25 Auxiliary voltage transformer tappings Note: An auxiliary voltage transformer is always included as standard in NXC regenerative lowharmonic drives. If the drive is ordered with an auxiliary voltage transformer for 230V auxiliary voltage supply (+ATx option) the tappings of the transformer have to be set according to the mains voltage. The tappings of the transformer in 500V drives is by default set to 400V and in 690V drives to 690V unless otherwise ordered.
26 • vacon 5.6 5.6.1 MOUNTING Cooling Free space around the cabinet Enough space must be left above and in front of the cabinet to ensure sufficient cooling and space for maintenance.

As a rule of thumb, cables and the fuses can be dimensioned according to the frequency converter nominal OUTPUT current which you can find on the rating plate. Dimensioning according to the output current is recommended because the frequency converter input current never significantly exceeds the output current.

CABLING AND CONNECTIONS 6.2.2.2 vacon • 41 Installation of ferrite rings (+OCM) on the motor cable Modern PWM Frequency converters based on IGBT transistors generate output pulses having short rise times (0,1...0,2 µs). Those pulse edges increase the stress for motor insulation and also generate high frequency common mode voltages on the motor output. Common mode voltage increases emitted radio interferences and might cause danger of bearing currents when larger motor frames (> 100kW) are used.

COMMISSIONING COMMISSIONING 10.1 Safety Before commissioning, note the following directions and warnings: 1 2 3 4 5 6 Internal components and circuit boards of the frequency converter (except for the galvanically isolated I/O terminals) are live when Vacon NX is connected to mains potential. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury.
COMMISSIONING 7 vacon • 95 Set the parameters of group 1 (See Vacon All in One Application Manual) according to the requirements of your application. At least the following parameters should be set: - motor nominal voltage motor nominal frequency motor nominal speed motor nominal current You will find the values needed for the parameters on the motor rating plate.
96 • vacon 10 Connect the motor to the process (if the startup test was run without the motor being connected) a) Before running the tests, make sure that this can be done safely. b) Inform your co-workers of the tests. c) Repeat test 8A or 8B. 10 Tel.
