1.2 Warnings
The components of the power unit of the frequency converter are
Vacon NX_ is connected to mains potential.
The motor terminals U, V, W and the DC-link/brake resistor terminals are
After disconnecting the frequency converter from the mains, wait until the fan
stops and the indicators on the keypad go out (if no keypad is attached see the
indicators on the cover). Wait 5 more minutes before doing any work on Vacon
NX_ connections. Do not even open the cover before this time has expired.
Always ensure absence of voltage before starting any electrical work!
The control I/O-terminals are isolated from the mains potential. However,
the relay outputs and other I/O-terminals may have a dangerous control
voltage present even when Vacon NX_ is disconnected from mains.
Before connecting the frequency converter to mains make sure that the
Vacon NX_ front and cable covers are closed.
If Vacon NX_ is disconnected from mains while running the motor,
it remains live if the motor is energized by the process. In this case the
motor functions as a generator feeding energy to the frequency converter.
when
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.
The earth leakage current of Vacon NX_ frequency converters exceeds
3.5 mA AC. According to standard EN61800-5-1, a reinforced protective
ground connection must be ensured. See Chapter 1.4.
If the frequency converter is used as a part of a machine, the machine
manufacturer is responsible for providing the machine with a disconnecting
device (EN 60204-1).
Only spare parts delivered by Vacon can be used.
After the power-up, power brake or fault reset the motor will start immediately if the start signal is active, unless the pulse control for Start/Stop
logic has been selected. Futhermore, the I/O functionalities (including start
inputs) may change if parameters, applications or software are changed.
Disconnect, therefore, the motor if and unexpected start can cause danger.
Prior to measurements on the motor or the motor cable, disconnect the
motor cable from the frequency converter.

1.4 Earthing and earth fault protection
The Vacon NX_ frequency converter must always be earthed with an earthing conductor connected to the
earthing terminal .
The earth leakage current of Vacon NX_ exceeds 3.5 mA AC. According to EN61800-5-1, one or more of the
following measures shall be applied, unless the touch current can be shown to be less than 3.5 mA AC or
10 mA DC:
A fixed connection and
a. The protective earthing conductor shall have a cross-sectional area of at least 10 mm
16 mm
or
b. An automatic disconnection of the supply in case of loss of continuity of the protective earthing conductor.
See Chapter 6.
or
c. Provision of an additional terminal for a second protective earthing conductor of the same cross-
sectional area as the original protective earthing conductor.

Al,
is a certain procedure according to which the tests shall be performed.
Ignoring this procedure may result in damaged product.
Do not touch the components on the circuit boards. Static voltage discharge
may damage the components.
If a fault protection relay is used, it must be of at least type B, preferably
B+ (according to EN 50178) , with a trip level of 300 mA. This is for fire
protection, not for touch protection in grounded systems.

The values above are valid only if the protective earthing conductor is made of the same metal as the phase
conductors. If this is not so, the cross-sectional area of the protective earthing conductor shall be determined
in a manner which produces a conductance equivalent to that which results from the application of this table.
Table 1. Protective earthing conductor cross-section
The cross-sectional area of every protective earthing conductor which does not form part of the supply
cable or cable enclosure shall, in any case, be not less than:
- 2,5 mm
- 4 mm
shall be made so that the protective earthing conductor in the cord shall, in the case of
failure of the strain-relief mechanism, be the last conductor to be interrupted.

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.
Due to the high capacitive currents present in the frequency converter, fault current protective switches
may not function properly.

For your own safety, please pay special attention to the instructions marked with the following symbols:
MOTOR RUN CHECK LIST

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.
