Introduction vacon • 5

1. I

The VACON® NXP System Drive is a comprehensive configured common DC bus drive line up for heavy-industry needs where round-the-clock activity is required leaving little time for maintenance.

All sections are grouped depending on their functionality, making it possible to plan each installation phase according to your requirements. The engineered sections slot in alongside each other allowing you to arrange integrated transport splits to save space. Alternatively, you can add extra transport sections to speed up installation. All larger modules have slide-out mechanics for easier set-up and maintenance.

The VACON® NXP System Drive is built to last. Items such as busbar systems and high/low power devices are separated into individual compartments away from each other. This means that, if an issue occurs, it is compartmentalized and doesn’t cause widespread failure helping to reduce lifetime and maintenance costs.

1.7 Storage

If the system drive is to be kept in store before use, make sure that the ambient conditions are acceptable:

• Storing temperature –40…+70 °C

• Relative humidity <95%, no condensation

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

If the drive is to be stored during longer periods, the power should be connected to the 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 300-500 mA 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 (1.35xUn 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.

1.8 Lifting and moving the cabinet sections

For transport, the system drive is split into smaller sections. The cabinet sections are delivered either in a wooden box or a wooden cage. The cabinets are transported vertically. Always refer to shipping marks for more detailed information. To lift the cabinet sections, use lifting equipment capable of handling the weight of the cabinets.

There are lifting beams on the top of the cabinets. Use the beams to lift and to move the cabinets to the required location.

Figure 1. Lifting the cabinet sections

Moving of the cabinets on site can be carried out as follows by a forklift truck, a hoist or on rollers:

• Lower the package onto a level base

• Remove the package covering only at the site of installation

• Low, narrow or convoluted transport routes may require removal of the pallet prior to movement

• Move packages in the upright position only

Figure 2. Moving the cabinet sections

Switchgear parts can easily topple backwards when manoeuvring on rollers or manual trolleys because their centre of gravity is typically located high up at the rear of the unit.

vacon • 12 Safety

9000.emf

2.1 Warnings

The components of the power unit and all cabinet mounted devices are live when the drive is connected to mains potential. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury.

The motor terminals U, V, W, the DC bus/brake resistor terminals and all other mains devices are potentially live when the drive is connected to mains, 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 the connections of the drive. Do not open the cabinet door before this time has expired. After expiration of this time, use measuring equipment to absolutely ensure that no voltage is present. Always

ensure the 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 the drive is disconnected from mains.

Before connecting the drive to mains make sure that the drive front and cable covers as well as the cabinet doors are closed.

Wear protective gloves when you do mounting, cabling or maintenance operations. There can be sharp edges in the AC drive that can cause cuts.

Safety vacon • 13

13006.emf

2.2 Cautions

VACON® AC drives are meant for

fixed installations only

Do not perform any measurements when the AC drive is connected to mains.

The touch current of VACON® AC drives exceeds 3.5 mAAC. According to standard EN61800-5-1, a reinforced protective ground connection must be ensured. See

Chapter 2.3.

If the drive is used as a part of a machine, the machine manufacturer is responsible for providing the machine with a supply disconnecting device (EN60204-1).

Only spare parts delivered by Danfoss can be used.

At 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 an unexpected start can cause danger.

The motor starts automatically after automatic fault reset if the autoreset function is activated. See the Application Manual for more detailed information.

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

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

Check that the EMC level of the AC drive corresponds to the requirements of the supply network.

Make sure that the cooling is sufficient. If the AC drive becomes frequently too hot, the lifetime of the drive will be shorter than usually.

2.3 Grounding and ground fault protection

CAUTION!

The AC drive must always be grounded with a grounding conductor connected to the grounding terminal marked with:

The touch current of the AC drive exceeds 3.5 mA AC. According to EN61800-5-1, one or more of the following conditions for the associated protective circuit shall be satisfied:

A fixed connection and

• the protective grounding conductor shall have a cross-sectional area of at least 10 mm2 Cu or 16 mm2 Al, or

• an automatic disconnection of the supply in case of discontinuity of the protective grounding conductor, or

• provision of an additional terminal for a second protective grounding conductor of the same cross-sectional area as the original protective grounding conductor.

Table 5. Protective grounding conductor cross-section

Cross-sectional area of phase conductors (S)

[mm2]

≤16

16<S≤35

35<

Minimum cross-sectional area of the corre-

sponding protective grounding conductor

[mm2]

The values above are valid only if the protective grounding conductor is made of the same metal

as the phase conductors. If this is not so, the cross-sectional area of the protective grounding

conductor shall be determined in a manner which produces a conductance equivalent to that

which results from the application of this table.

The cross-sectional area of every protective grounding conductor which does not form part of the supply cable enclosure shall, in any case, be no less than:

• 2.5 mm2 if mechanical protection is provided or

• 4 mm2 if mechanical protection is not provided. For cord-connected equipment, provisions shall be made so that the protective grounding conductor in the cord shall, in the case of failure of the strain-relief mechanism, be the last conductor to be interrupted.

However, always follow the local regulations for the minimum size of the protective grounding conductor.

NOTE! Due to the high capacitive currents present in the AC drive, fault current protective switches

may not function properly.

Do not perform any voltage withstand tests on any part of the AC drive. There is a certain procedure according to which the test shall be performed. Ignoring this procedure may result in a damaged product.
