in Chapter 1.

3. Before the mechanical installation, check the minimum clearances around the

unit and check the ambient conditions in Chapter 5.

4. Check the size of the motor cable, DC supply cable, and mains fuses, and check

the cable connections. Read Chapters 6.1.1.1 –

5. Follow the installation instructions, see Chapter 6.1.1.8.

6. The sizes and earthing of control connections are explained in Chapter 6.2.1.

7. If the Start-Up wizard is active, select the language you want the keypad and the

6.1.1.6.

application to use and confirm by pressing the enter button. If the Start-Up
wizard is not active, follow the instructions in 7a and 7b below.

8. 7a. Select the language of the keypad from Menu M6, page 6.1. Instructions on

using the keypad are given in Chapter 7.

9. 7b. Select the application you want to use from Menu M6, page 6.2. Instructions

on using the keypad are given in Chapter 7.

10. All parameters have factory default values. To ensure proper operation, check

the rating plate data for the values below and the corresponding parameters of
parameter group G2.1.

• nominal voltage of the motor

The DC supply and motor terminals are

connected to DC supply,
The control I/O-terminals are isolated from the mains potential.

However, the relay outputs and other I/O-terminals may have dangerous
control voltage present even when the Vacon NX is disconnected from the
DC supply.

The inverter has a large capacitive leakage current.

If the inverter is used as a part of a machine, the machine manufacturer
is responsible for providing the machine with a main switch (EN 60204-1).

Only spare parts delivered by Vacon can be used.

The Vacon NX inverter is meant for fixed installations only.

Do not perform any measurements when the inverter is connected to the

After having disconnected the inverter from the DC supply, wait until the
fan stops and the indicators on the keypad go out (if no keypad is
attached see the indicator through the keypad base). Wait 5 more
minutes before doing any work on Vacon NX connections. Do not even
open the cover before this time has expired.

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.

Prior to measurements on the motor or the motor cable, disconnect the
motor cable from the inverter.

Do not touch the components on the circuit boards. Static voltage dis­charge may damage the components.

Before connecting the inverter to DC supply, make sure that the Vacon

WARNING

1.3 Earthing and earth fault protection

The Vacon NX inverter must always be earthed with an earthing conductor connected to the earthing
terminal.

The earth fault protection inside the inverter only protects the inverter against earth faults in the
motor or the motor cable.

Due to the high capacity currents present in the inverter, fault current protective switches may not
function properly. If fault current protective switches are used, they need to be tested with earth
fault currents present during possible fault situations.

1.4 Running the motor

Before starting the motor, check that the motor is mounted properly and
ensure that the machine connected to the motor allows the motor to be
started.

Set the maximum motor speed (frequency) according to the motor and
the machine connected to it.

Before reversing the motor, make sure that this can be done safely.

Make sure that no power correction capacitors are connected to the
motor cable.

Make sure that the motor terminals are not connected to mains
potential.
