1.3 Danger

The components of the power unit of VACON® 100 X drives 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 brake resistor terminals and the DC-terminals are live when VACON® 100 X Drive is connected to the mains, even if the motor is not running.

After disconnecting the AC drive from the mains, wait until the indicators on the keypad go out (if no keypad is connected, see the indicators on the cover). Wait an additional 30 seconds

before doing any work on the connections of VACON this time has expired. After expiration of this time, use measuring equipment to absolutely ensure that no

voltage is present.

Always ensure absence of voltage before starting any elec-

100 X Drive. Do not open the unit before

Before connecting the AC drive to mains make sure that the powerhead of VACON Drive is mounted firmly on the terminal box.

During a coast stop (see the Application Manual), the motor is still generating voltage to the drive. Therefore, do not touch the components of the AC drive before the motor has completely stopped and wait until the indicators on the keypad go out (if no keypad is connected, see the indicators on the cover). Wait an additional 30 seconds before starting any work on the drive.

1.4 Warnings

VACON® 100 X AC drive is meant for fixed installations (on the motor or on the wall) only.

Only DVC A circuits (Decisive Voltage Class A, according to IEC 61800-5-1) are allowed to be connected to the control unit. This advice aims to protect both the drive

and the client-application. VACON damages resulting from unsafe connections of external circuits to the drive. See paragraph 1.6 for more details.

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

The touch current of VACON dard EN61800-5-1, a reinforced protective ground connection must be ensured. See paragraph 1.5 for more details.

If the AC drive is used as a part of a machine, the machine manufacturer is responsi- ble for providing the machine with a supply disconnecting device (EN 60204-1). See paragraph 4.1 for more details.

100 X AC drives exceeds 3.5mA AC. According to stan-

Only spare parts delivered by VACON® can be used.

At power-up or fault reset, the motor will start immediately if the start signal is active, unless the pulse control for are ready to be used (normal operation). 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. This is valid only if STO inputs are energized. For prevention on unexpected restart, use appropriate safety relay connected to the STO inputs.

The motor starts automatically after automatic fault reset if the autoreset function is activated. See the Application Manual for more detailed information. This is valid only if STO inputs are energized. For prevention on unexpected restart, use appropriate safety relay connected to the STO inputs.

Before performing any measurement on the motor or on the motor cable, disconnect the motor cable from the AC drive.

Do not perform any voltage withstand test on any part of VACON® 100 X. The tests shall be performed according to a specific procedure. Ignoring this procedure may damage the product.

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

Check that the EMC level of the AC drive corresponds to the requirements of your supply network. See paragraph 6.2 for more details.

In a domestic environment, this product may cause radio interference in which case supplementary mitigation measures may be required.

vacon • 5 Safety

1.5 Earthing and earth fault protection

CAUTION!

The VACON® 100 X AC drive must always be earthed with an earthing conductor connected to the earthing terminal marked with .

See Table 12 and Table 13 for the required cross-section of phase conductor and protective earthing conductor (both made of copper).

Since the touch current exceeds 3.5 mA AC, according to EN61800-5-1, the MM4 and MM5 shall have a fixed connection and provision of an additional terminal for a second protective earthing conductor of the same cross-sectional area as the original protective earthing conductor. MM6 shall have a fixed installation and a cross-section of the protective earthing conductor of at least 10

Cu.

On the terminal-box, three screws (for MM4 and MM5) and two screws (for MM6)are provided for ORIGINAL and MOTOR protective earthing conductors: the customer can choose the screw for each one.

The cross-sectional area of every protective earthing conductor which does not form a 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 power-head is earthed through metal aglets, located on the terminal-box, which fit into spring baskets on the powerhead. See Figure 1, Figure 2 and Figure 3 for the location of the screws (three for MM4 and MM5, two for MM6) and the metal aglets (one for MM4 and MM5, two for MM6). Please, pay attention not to damage or remove these aglets.

1.6 Insulation system

Please, consider carefully the insulation system depicted in Figure 4 before connecting any circuit to the unit.

A distinction has to be made for the following three groups of terminals, according the insulation system of VACON® 100 X:

• Mains and motor connections (L1, L2, L3, U, V, W)

• Relays (R01, R02)

• Thermistor-input

• Control terminals (I/Os, RS485, Ethernet, STO)

The Control terminals (I/Os, RS485, Ethernet, STO) are isolated from the Mains (the insulation is reinforced, according to IEC 61800-5-1) and the GND terminals are referred to PE.

(*)

This is important when you need to connect other circuits to the drive and test the complete assem-

bly. Should you have any doubt or question, please contact your local VACON

distributor.

(*)

The relays may be used also with DVC A circuits. This is possible only if both relays

1.7 Compatibility with RCDs

This product can cause a d.c. current in the protective earthing conductor. Where a residual current-operated protective (RCD) or monitoring (RCM) device is used for protection in case of direct or indirect contact, only an RCD or RCM of Type B is allowed on the supply side of this product.

1.8 Extended temperature range

VACON® 100 X has an integrated cooling system, independent from the motor fan. Under maximum operating conditions, the ambient temperature cannot exceed 40 °C. See Table 24 and Table 25 for the output rated current. Higher temperatures are allowed only with derating of the output current. With derating the unit can operate up to 60°C. See the Figure 5.

Figure 5. Temperature-output current derating curve.

NOTE: the maximum allowed switching frequency above 50°C is 1.5 kHz. The AC drive is cooled down by air-ventilation. Therefore, make sure that enough free space is left

around the AC drive to ensure sufficient air circulation (see for more details the mounting instructions on chapter 3).

1.9 Electro-magnetic compatibility (EMC)

The VACON® 100 X complies with IEC 61000-3-12, provided that the short circuit power (SSC) is greater than or equal to 120 at the interface point between the user's supply and the public system. It is the responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is connected only to a supply with a short-circuit power SSC greater than or equal to 120.

3.2 Introduction of modules

The mechanical concept of VACON® 100 X drive is based on two segregated parts, power and control, connected to each other by pluggable terminals. The power unit, called powerhead, includes all the power electronics such as the EMC-filter, IGBTs, capacitors, choke or power boards while the control board and the control terminals are located in the terminal box.

Figure 14. VACON® 100 X drive modules.

Mounting vacon • 24

3.3 Mounting

The drive consists of two main elements:

1. The terminal box that includes the power terminals and control board with the control terminals

and

2. The powerhead containing all the power electronics.

To install the drive, both parts need to be separated. The terminal box must be fixed first and all cabling done. After this, the powerhead will be plugged on the terminal box and fixed with 4 (MM4 and MM6) or 6 (MM5) dedicated screws located on top side of the powerhead (see Figure 15.). In order to guarantee specified IP protection, recommended fastening torque is 2-3 Nm. The screws should be tightened crosswise.

Figure 15. Separation of modules(MM5 example).

vacon • 25 Mounting

3.3.1 Wall-mounting

The drive can be mounted in vertical or horizontal position on the wall or any other relatively even mounting plane or machine frame and fixed with the screws recommended in Table 7.

Recommended screw or bolt size for MM4 is M5, for MM5 M6 and MM6 is M8.

Frame Screw number Screw size

MM4 4 M5 MM5 4 M6 MM6 4 M8

Table 7. Screws for wall mounting.

3.3.2 Motor-mounting

The drive can also be mounted on a motor (on top or on any side of the motor). The drive is equipped with a cooling system independent of the motor. Motor-mounting requires special adapting components. Contact your local VACON

distributor for additional information.

3.3.3 Segregated modules

In order to ease replacements in case of failure, the power and the control sub-systems are enclosed in two segregated parts, connected together through pluggable terminals:

• Power-head: heat-sink enclosing all power electronics

• Terminal-box: block containing unit control and power terminals

Firstly, the terminal-box has to be fixed and the cabling has to be done. Secondly, the power-head has to be plugged and fixed to the terminal-box with dedicated screws (see Table 8). In order to preserve the specified IP protection class, the recommended fastening torque is 2-3 Nm.

3.4 Cooling

The AC drive produces heat in operation and is cooled down by air circulated by a fan. The cooling concept is independent of the motor fan.

Enough free space shall be left around the AC drive to ensure sufficient air circulation and cooling. Different acts of maintenance may also require a certain amount of free space.

The minimum clearances given in Table 9 must not be exceeded. It is also important to ensure that the temperature of the cooling air does not exceed the maximum ambient temperature of the converter.
