1. SAFETY

1.1 Warnings

1

The components of the power unit of the inverter are live when the
VACON® NX is connected to DC supply. Coming into contact with this
voltage is extremely dangerous and may cause death or severe
injury. The control unit is isolated from mains potential.

2

The DC supply and motor terminals are live when the VACON® NX is
connected to DC supply, even if the motor is not running.

3

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.

4

The inverter has a large capacitive leakage current.

5

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).

6

Only spare parts delivered by manufacturer can be used.

1.2 Safety instructions

1

The VACON® NX inverter is meant for fixed installations only.

1.3 Grounding and earth fault protection

The VACON® NX inverter must always be earthed with an grounding conductor connected to the
grounding 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.

3.2 Storage

If VACON® NX Inverter is to be stored before use, make sure that the ambient conditions are
acceptable:

Storage temperature: -40...+158°F)
Relative humidity: 0 to 95%, no condensation

If you must keep the VACON® NX Active Front End in storage for a long time, you must connect the
power to the VACON® NX Active Front End each year. Keep the power on for a minimum of 2 hours.
We do not recommend a long storage time. If the storage time is more than 12 months, you must
charge the electrolytic DC capacitors with caution. To reform the capacitors, obey the instructions in
Chapter 3.2.1 Capacitor reforming.

3.2.1

Capacitor reforming

After a long storage time, it is necessary to reform the capacitors to prevent damage to the
capacitors. To make sure that the possible high leakage current through the capacitors stays in
minimum, use a DC-power supply with an adjustable current limit.

1. Set the current limit to 300-800mA to agree with the size of the drive.

2. Connect the DC-power supply to the B+/Bterminals (DC+ to B+, DC- to B-) of the DC-link or
directly to the capacitor terminals.

3. Set the DC-voltage to the nominal DC-voltage level of the Active Front End (1.35*Un AC) and
keep the power on for 1 hour, at minimum. If the Active Front End was in store for much longer
than 12 months and the capacitors were not charged, speak to the factory to get instructions
before you connect the power.

3.3 Maintenance

All technical devices, drives as well, need a certain amount of care-taking and failure preventive
maintenance. To maintain trouble-free operation of the drive, environmental conditions, as well as
load, line power, process control, etc. have to be within specifications, determined by manufacturer.

If all conditions are in accordance with the manufacturer's specifications, there are no other
concerns, but to provide a cooling capacity high enough for the power- and control circuits. This
requirement can be met by making sure, that the cooling system works properly. Operation of
cooling fans and cleanness of the heat sink should be verified regularly.

Regular maintenance is recommended to ensure trouble free operation and long lifetime of the
drive. At least the issues listed in the following table should be included in the regular maintenance.

maintenance.

3.4 Disposal

When the drive is at the end of its operation life, do not
discard it as a part of municipal waste. You can recycle
the primary components of the drive. You must
disassemble some components before you can remove
the different materials. Recycle the electrical and
electronic components as waste.

To make sure that the waste is recycled correctly, send
the waste to a recycling centre. You can also send the
waste back to the manufacturer. Obey the local and
other applicable regulations.

4. TECHNICAL DATA

4.1 Introduction

The figure below presents the block diagram of the VACON® NX inverter. The inverter mechanically
consists of two units, the Power Unit and the Control Unit.

The Power Unit contains an inverter bridge which consists of IGBT switches and produces a
symmetrical, 3-phase PWM-modulated AC voltage to the motor.

The Motor and Application Control Block is based on microprocessor software. The microprocessor
controls the motor based on the information it receives through measurements, parameter settings,
control I/O and control keypad. The motor and application control block controls the motor control
ASIC which, in turn, calculates the IGBT positions. Gate drivers amplify these signals for driving the
IGBT inverter bridge.

The control keypad constitutes a link between the user and the inverter. The control keypad is used
for parameter setting, reading status data and giving control commands. It is detachable and can be
operated externally and is connected via a cable to the inverter. Instead of the control keypad, a PC
can be used to control the inverter if connected through a similar cable (VACON RS232PC 1.5M).

The basic control interface and the parameters (the Basic Application) are easy to use. If a more
versatile interface or parameters are required, a more suitable application can be chosen from the
"All in One+" Application Package. See the "All in One+" Application Manual for more information on
the different applications.

Optional I/O expander boards that increase the number of inputs and outputs to be used are also
available. For more information, contact the Manufacturer or your local distributor (see back cover).

Overload capability

The low overload means that if 110% of the continuous current (IL) is required for 1 minute
every 10 minutes, the remaining 9 minutes must be approximately 98% of IL or less. This is to
make sure that the output current is not more than IL during the duty cycle.

Local contacts: https://www.danfoss.com/en/contact-us/contacts-list/

4.4.1

Ambient temperature

The power rating of the Active Front End unit is valid for an ambient temperature of 40 ºC (104 °F). If
the device is to be used in higher ambient temperatures, its power rating must be subjected to
derating. The derating coefficient from 40 °C to 50 °C, use derating factor 1.5 %/1 °C, and from 50 °C
to 55 °C, use derating factor 2.5 %/1 °C, for ambient temperatures not exceeding 55 °C (131 °F). The
reduced power is calculated using the formula:

Pde = Pn *((100% - (t - 40 ºC)*X)/100)
Pn = nominal power of the unit
t = ambient temperature
x = derating coefficient

High altitude installation

The density of air decreases when the altitude increases and the pressure decreases. When the air
density decreases, the thermal capacity decreases (i.e. less air removes less heat) and the
resistance to electric field (breakdown voltage / distance) decreases.

The full thermal performance of VACON® NX AC drives is designed for installation up to 1000 m
altitude and the electric insulation is designed for installations up to 2000 m altitude. Higher
installation locations are possible, when you obey the derating guidelines in this chapter.

NOTE! 690V units maximum installation altitude is 2000m.
Above 1000 m, you must decrease the limited maximum load current by 1% for each 100 m. Thus, for

example, at 2500 m altitude, you must decrease the load current down to 85% of the rated output
current (100% (2500 m 1000 m) / 100 m x 1% = 85%).

When you use fuses at high altitudes, the cooling effect of the fuse decreases as the density of the
atmosphere decreases.

When you use fuses above 2000 meters, the continuous rating of the fuse:

I = In*(1- (h-2000)/100*0.5/100)
I = Current rating at high altitude
In = Rated current of a fuse

5.1 Mounting

The inverter can be mounted in a vertical position on the back plane of a cubicle. Enough space must
be reserved around the inverter to ensure sufficient cooling, see Figure 5-7. Follow the minimum
dimensions for installation, see Table 5-1 and Table 5-2. Also make sure that the mounting plane is
relatively even. The inverter is fixed with four screws (or bolts, depending on the unit size). The
dimensions for installation are presented in Figure 5-7 and Table 5-1.The following pages show the
dimensions for IP00 power module.
