1. SAFETY

ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT THE ELECTRICAL INSTALLATION

= DANGEROUS VOLTAGE!

= WARNING or CAUTION

1.1 Warnings

The VACON

NX AC drive is meant for fixed installations only.

Do not perform any measurements when the AC drive 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.

The AC drive has a large capacitive leakage current.

If the AC drive 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 the manufacturer can be used.

The motor starts at power-up if the start command is 'ON'. Furthermore, the I/O functionalities (including start inputs) may change if parameters, applications or software are changed. Disconnect, therefore, the motor if an unexpected start can cause danger.

Prior to measurements on the motor or the motor cable, disconnect the motor cables from the AC drive.

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

1.2 Safety instructions

The components of the power unit of the AC drive and all cabinet mounted devices are potentially live when VACON

contact with this voltage is extremely dangerous and may cause death or severe injury.

The motor terminals U, V, W and the DC-link/brake resistor terminals –/+ and all other mains devices are potentially live when VACON

even if the motor is not running. After disconnecting the AC drive 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

not even open the cabinet door before this time has expired. 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 AC drive to mains make sure that the VACON cable covers as well as the cabinet doors are closed.

NOTE! 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.

1.3 grounding and earth fault protection

The VACON® NX AC drive must always be earthed with an grounding conductor connected to the PE bar in the lower front side of the cabinet.

The earth fault protection inside the AC drive protects only the converter itself against earth faults in the motor or the motor cable. It is not intended for personal safety.

NOTE! Due to the high capacitive currents present in the AC drive, fault current protective switches may not function properly.

3.3 Storage

If the AC drive 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

The environment should also be free from dust. If there is dust in the air the AC drive should be well protected to make sure dust does not get into the AC drive.

If the AC drive is to be stored during longer periods the power should be connected to the AC drive once in 24 months and kept on for at least 2 hours. If the storage time exceeds 24 months the electrolytic DC capacitors need to be charged with caution. Therefore, such a long storage time is not recommended.

If the storing time is much longer than 24 months, the recharging of the capacitors has to be carried out so that the possible high leakage current through the capacitors is limited. The best alternative is to use a DC-power supply with adjustable current limit. The current limit has to be set for example to 300…500mA and the DC-power supply has to be connected to the B+/B- terminals (DC supply terminals).

DC-voltage must be adjusted to nominal DC-voltage level of the unit (1.35*Un AC) and supplied at least for 1 hour.

If DC-voltage is not available and the unit has been stored de-energized much longer than 1 year consult factory before connecting power.

5.2 Lifting the unit out of the transport packaging

The unit is delivered either in a wooden box or a wooden cage. 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.

There are lifting lugs on the top of the cabinet and these lugs can be used to lift the cabinet into an upright position and to move it to the place needed.

5.3 Fixing the unit to the floor or to the wall

Before starting the installation work make sure that the level of the floor is within acceptable limits. The maximum deviation from the basic level can be no more than 5 mm over 3 m distance. The maximum acceptable height difference between cabinet front and rear edges should be within +2/0mm limit.

The cabinet should always be fixed to the floor or to the wall. Depending on installation conditions, the cabinet sections can be fixed in different ways. There are holes in the front corners which can be used for fixing. Additionally, the rails on the top of the cabinet have fixing lugs for fixing the cabinet to the wall.

Welding of the cabinet might risk sensitive components in the AC drive. Ensure that no grounding currents can flow through any part of the AC drive.

5.3.1 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. In AC drives consisting of more than one cabinet section, fix all sections in the same way.

5.3.2 Fixing to the floor only

NOTE! This option is not available for FR13 and bigger units. For fixing FR13 and bigger units see delivery specific documentation.

If bottom-only fixing is used, additional fixing brackets (Rittal part.nr. 8800.210) or equivalent are necessary. Fix the cabinet to the floor in the front with bolts and use the fixing brackets in the middle. Fix all cabinet sections in the same way.

5.4 AC choke connections

NOTE! The NXC 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 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.

The NXC 6- and 12-pulse AC drive is equipped with one or more input AC chokes. The chokes have two inductance levels to optimise the functionality at different supply voltages. In the installation phase, the wiring of the chokes should be checked and changed if needed (not for FR9).

The input is always connected to terminal #1 (see picture below) and should not be changed. The output of the choke should be connected to terminal #2 or #3 (see picture below) according to the table below. The terminals are marked with inductance values and applicable voltage.

In units FR10 to FR12, the connection is changed by moving the cable to the appropriate terminals. In FR13/14, the bridges of the busbar connection should be moved according to the settings shown in the table.

In units with two or more parallel chokes (some FR11 as well as all FR12 and FR13) all chokes have to be wired in the same way. If chokes are wired differently the AC drive may be damaged.

5.5 Auxiliary voltage transformer tappings

NOTE! An auxiliary voltage transformer is always included as standard in NXC low-harmonic 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 or 500V and in 690V drives

to 690V unless otherwise ordered. Locate the transformer in the lower part of the cabinet. The primary side of the transformer has

tappings that correspond to standard main voltages. Change to tapping to correspond to the mains voltage in use.
