Danger! Dangerous electrical voltage!

Before commencing the installation

• Disconnect the power supply of the device.

• Ensure that devices cannot be accidentally restarted.

• Verify isolation from the supply.

• Earth and short circuit the device.

• Cover or enclose any adjacent live components.

• Follow the engineering instructions (IL04020001E) for the device concerned.

• Only suitably qualified personnel in accordance with EN 50110-1/-2 (VDE 0105 Part 100) may work on this device/system.

• Before installation and before touching the device ensure that you are free of electrostatic charge.

• The functional earth (FE, PES) must be connected to the protective earth (PE) or the potential equalisation. The system installer is responsible for implementing this connection.

• Connecting cables and signal lines should be installed so that inductive or capacitive interference does not impair the automation functions.

• Install automation devices and related operating elements in such a way that they are well protected against unintentional operation.

• Suitable safety hardware and software measures should be implemented for the I/O interface so that an open circuit on the signal side does not result in undefined states in the automation devices.

• Ensure a reliable electrical isolation of the extra-low voltage of the 24 V supply. Only use power supply units complying with IEC 60364-4-41 (VDE 0100 Part 410) or HD384.4.41 S2.

• Deviations of the mains voltage from the rated value must not exceed the tolerance limits given in the specifications, otherwise this may cause malfunction and dangerous operation.

• Emergency stop devices complying with IEC/EN 60204-1 must be effective in all operating modes of the automation devices. Unlatching the emergency-stop devices must not cause a restart.

• Devices that are designed for mounting in housings or control cabinets must only be operated and controlled after they have been installed and with the housing closed. Desktop or portable units must only be operated and controlled in enclosed housings.

• Measures should be taken to ensure the proper restart of programs interrupted after a voltage dip or failure. This should not cause dangerous operating states even for a short time. If necessary, emergency-stop devices should be implemented.

• Wherever faults in the automation system may cause injury or material damage, external measures must be implemented to ensure a safe operating state in the event of a fault or malfunction (for example, by means of separate limit switches, mechanical interlocks etc.).

• Depending on their degree of protection, adjustable frequency drives may contain live bright metal parts, moving or rotating components or hot surfaces during and immediately after operation.

• Removal of the required covers, improper installation or incorrect operation of motor or adjustable frequency drive may cause the failure of the device and may lead to serious injury or damage.

• The applicable national accident prevention and safety regulations apply to all work carried on live adjustable frequency drives.

• The electrical installation must be carried out in accordance with the relevant regulations (e. g. with regard to cable cross sections, fuses, PE).

• Transport, installation, commissioning and maintenance work must be carried out only by qualified personnel (IEC 60364, HD 384 and national occupational safety regulations).

• Installations containing adjustable frequency drives must be provided with additional monitoring and protective devices in accordance with the applicable safety regulations. Modifications to the adjustable frequency drives using the operating software are permitted.

Eaton Corp.

Safety instructions

• All covers and doors must be kept closed during operation.

• To reduce the hazards for people or equipment, the user must include in the machine design measures that restrict the consequences of a malfunction or failure of the drive (increased motor speed or sudden standstill of motor). These measures include:

– Other independent devices for monitoring safety-related

variables (speed, travel, end positions etc.).

– Electrical or non-electrical system-wide measures

(electrical or mechanical interlocks).

– Never touch live parts or cable connections of the adjustable

frequency drive after it has been disconnected from the power supply. Due to the charge in the capacitors, these parts may still be live after disconnection. Fit appropriate warning signs.

frequency converters are divided into three voltage

categories:

• 100 V (MMX11)

• 200 V (MMX12…, MMX32…)

• 400 V (MMX34…)

Mains supply voltages

The rated operating voltages stated in the following table are based on the standard values for networks with a grounded star point.

In ring networks (as found in Europe) the rated voltage at the transfer point of the power supply companies is the same as the value in the consumer networks (e.g. 230 V, 400 V).

In star networks (as found in North America), the rated voltage at the transfer point of the utility companies is higher than in the consumer network. Example: 120 V l 115 V, 240 V l 230 V, 480 V l 460 V.

The wide tolerance range of frequency inverter M-Max

takes

into account a permissible voltage drop of an additional 4 %

- 14 %) in load networks, while, in the 400 V category, it

takes into account the North American line voltage of 480 V +10 % (60 Hz).

The permissible connection voltages for the M-Max

series are

listed in the Technical Specifications section in the appendix.

The rated operational data of the mains voltage is always based on the mains frequencies 50/60 Hz (50 Hz -10 % - 60 Hz +10 %).

Units

Every physical dimension included in this manual uses international metric system units, otherwise known as SI (Système International d’Unités) units. For the purpose of the equipment's UL certification, some of these dimensions are accompanied by their equivalents in imperial units.

Selection criteria

04/10 MN04020001Z-EN

The frequency inverter c is selected according to the supply voltage U assigned motor b. The circuit type (

of the mains supply a and the rated current of the

D / Y) of the motor must be

selected according to the supply voltage a. The rated output current I

of the frequency inverter must be greater than/equal to

the rated motor current.

When connecting multiple motors in parallel to the output

of a frequency inverter, the motor currents are added geometrically – separated by effective and idle current components. When you select a frequency inverter, make sure that it can supply the total resulting current. If necessary, for dampening and compensating the deviating current values, motor reactors or sinusoidal filters must be connected between the frequency inverter and the motor.

The parallel connection of multiple motors in the output of the frequency inverter is only permitted with U/f-characteristic curve control.

If you connect a motor to an operational frequency

inverter, the motor draws a multiple of its rated operational current. When you select a frequency inverter, make sure that the starting current plus the sum of the currents of the running motors will not exceed the rated output current of the frequency inverter.

Switching in the output of the frequency inverter is only permitted with U/f-characteristic curve control.

The speed control with slip compensation (P11.8)

increases the drive dynamics and optimizes the output. For this the frequency inverter processes all motor data in an electrical image.

Figure 8: Selection criteria

When selecting the drive, the following criteria must be known:

• Type of motor (three-phase asynchronous motor)

• Mains voltage = rated operating voltage of the motor (e.g. 3 AC ~ 400 V),

• Rated motor current (guide value, dependent on the circuit type and the supply voltage)

• Load torque (quadratic, constant),

• Starting torque,

• Ambient temperature (rated value +40 °C).

The speed control operating mode (P11.8) must only be

used with single drives (one motor at the output of the frequency inverter). The rated current of the motor must be assigned to the rated operational current of the frequency inverter (same rating).

04/10 MN04020001Z-EN

Proper use

The M-MAX

frequency inverters are not domestic appliances.

They are designed only for industrial use as system components.

The M-Max

frequency inverters are electrical apparatus for controlling variable speed drives with three-phase motors. They are designed for installation in machines or for use in combination with other components within a machine or system.

After installation in a machine, the frequency inverters must not be taken into operation until the associated machine has been confirmed to comply with the safety requirements of Machinery Safety Directive (MSD) 89/392/EEC (meets the requirements of EN 60204). The user of the equipment is responsible for ensuring that the machine use complies with the relevant EU Directives.

The CE markings on the M-MAX

frequency inverter confirm that, when used in a typical drive configuration, the apparatus complies with the European Low Voltage Directive (LVD) and the EMC Directives (Directive 73/23/EEC, as amended by 93/68/EEC and Directive 89/336/EEC, as amended by 93/68/EEC).

In the described system configurations, M-MAX

frequency

inverters are suitable for use in public and non-public networks.

Proper use

A connection to IT networks (networks without reference to earth potential) is permissible only to a limited extent, since the device’s built-in filter capacitors connect the network with the earth potential (enclosure). On earth free networks, this can lead to dangerous situations or damage to the device (isolation monitoring required).

To the output of the frequency inverter (terminals U, V, W)

you must not:

• connect a voltage or capacitive loads (e.g. phase compensation capacitors),

• connect multiple frequency inverters in parallel,

• make a direct connection to the input (bypass).

Observe the technical data and connection requirements. For additional information, refer to the equipment nameplate or label at the frequency inverter and the documentation.

Any other usage constitutes improper use.

influences, repair is not possible. Dispose of the device in accordance with the respectively applicable environmental laws and provisions for the disposal of electrical or electronic devices.

Storage

If the frequency inverter is stored before use, suitable ambient conditions must be ensured at the site of storage:

• Storage temperature: -40 - +70 °C,

• Relative average air humidity: < 95 %, non condensing (EN 50178),

• To prevent damage to the DC link capacitors, storage times longer than 12 months are not recommended (see Section “Charging DC link capacitors”).

Charging DC link capacitors

After long storage times or long down times without a power supply (> 12 months), the capacitors in the DC link must undergo controlled recharging, in order to avoid damage.

For this the M-Max

frequency inverters must be fed with a regulated DC power supply unit via two mains connection terminals (e.g. L1, L2/N). To avoid any possible excessive leakage currents from the capacitors, the inrush current should be limited to around 300 to 800 mA (depending on the rating). In this case, the frequency inverter must not be enabled (no start signal). The DC voltage must then be set to the values of the corresponding DC link voltage (U

) and fed for around two hours (regeneration

time).

MMX11: Due to the internal voltage doubler circuit, the

capacitors cannot be recharged via the connection terminals. Contact your local sales partner.

Electrical power network

Mains connection and configuration

The frequency inverters of the M-Max

series can be connected and operated with all control-point grounded AC power networks (see IEC 60364 for more information in this regard).

L1 L2 L3 PEN

Figure 10: AC power networks with grounded center point (TN-/TT

networks)

While planning the project, consider a symmetrical

distribution to the three external conductors, if multiple frequency inverters with single phase supplies are to be connected. The total current of all single phase consumers is not to cause an overload of the neutral conductor (N-conductor).

The connection and operation of frequency inverters to asymmetrically grounded TN networks (phase-grounded Delta network "Grounded Delta", USA) or non-grounded or highresistance grounded (over 30 O) IT networks is only conditionally permissible.

If the M-Max

frequency inverters are connected to an asymmetrically grounded network or to an IT network (non grounded, insulated), the internal interference suppression filter must be disconnected (unscrew the screw marked EMC, a section “Electrical Installation”, page 37). The required filtering for electromagnetic compatibility (EMC) is then no longer present.

Measures for electromagnetic compatibility are

mandatory in a drive system, to meet the legal requirements for EMC- and low-voltage regulations.

Mains voltage and frequency

The standardized mains voltages (IEC 60038, VDE017-1) for energy suppliers (EVU) guarantee the following conditions at the transition points:

• Deviation from the rated value of voltage: maximum ±10 %

• Deviation in voltage phase balance: maximum ±3 %

• Deviation from rated value of the frequency: maximum ±4 %

The broad tolerance band of the M-Max

frequency inverter considers the rated value for European as (EU: U American as (USA: U

= 230 V/400 V, 50 Hz) and

= 240 V/480 V, 60 Hz) standard voltages:

• 120 V, 50/60 Hz at MMX11

• 230 V, 50 Hz (EU) and 240 V, 60 Hz (USA) at MMX12 und

MMX32,

• 400 V, 50 Hz (EU) and 480 V, 60 Hz (USA) at MMX34…

For the bottom voltage value, the permitted voltage drop of 4 % in the consumer circuits is also taken into account, therefore a total of U

- 14 %.

• 100 V device class (MMX11):

110 V -15 % - 120 V +10 % (94 V -0 % - 132 V +0 %)

• 200-V device class (MMX12, MMX32):

208 V - -15 % – 240 V + +10 % (177 V - 0 % – 264 V + 0 %)

• 400-V device class (MMX34):

380 V - -15 % – 480 V + +10 % (323 V - 0 % – 528 V + 0 %)

The permitted frequency range is 50/60 Hz here (45 Hz - 0 % – 66 Hz + 0 %).

Voltage balance

Because of the uneven loading on the conductor and with the direct connection of greater power ratings, deviations from the ideal voltage form and unsymmetrical voltages can be caused in three-phase AC power networks. These asymmetric divergences in the mains voltage can lead to different loading of the diodes in mains rectifiers with three-phase supplied frequency inverters and as a result, to an advance failure of this diode.

Good grounding measures are a prerequisite for the effective insert of further measures such as shielding or filters here. Without respective grounding measures, further steps are superfluous.

In the project planning for the connection of three-phase

supplied frequency inverters (MMX32, MMX34), consider only AC power networks that handle permitted asymmetric divergences in the mains voltage F +3 %.

If this condition is not fulfilled, or symmetry at the connection location is not known, the use of an assigned main choke is recommended (see “Appendix“, Section “Mains chokes”, page 169).

Total harmonic distortion (THD)

The THD (Total Harmonic Distortion) is a measurement for the occurring harmonic distortion of the sinusoidal oscillation (mains power side) input variables with the frequency inverter. It is given in percent of the total value.

With the frequency inverters of the M-Max

series, the permitted

value for the total harmonic distortion THD >120 %.

Idle power compensation devices

Compensation on the power supply side is not required for the

frequency inverters of the M-MAX

series. From the AC power supply network they only take on very little reactive power of the fundamental harmonics (cos

compensation devices, current deviations can enable parallel resonance and undefinable circumstances.

Mains reactors

A mains reactor (also called commutation inductors) increases the inductance of the power supply line. This extends the current flow period and dampens mains deviations.

On frequency inverters, a mains reactor limits the mains feedback to permissible values. The harmonic current emissions that are fed back into the mains network ("mains feedback") are reduced. This reduces the mains-side apparent current to about 30 %.

Towards the frequency inverter, the mains reactors dampen the interference from the supply network. This increases the withstand voltage of the frequency inverter and lengthens the lifespan (diodes of the mains power rectifier, intermediate circuit capacitors).

For the operation of the M-MAXTM frequency inverter, the

application of main chokes is not necessary. We do recommend however that an upstream main choke is used since the network quality is not known in most cases.

While planning the project, consider that a mains reactor is only assigned to a single frequency inverter for isolation. Using a large mains reactor for multiple small frequency inverters should therefore be avoided if at all possible.

When using an adapting transformer (assigned to a single frequency inverter), a main choke is not necessary.

Mains reactors are designed based on the mains-side input current

) of the frequency inverter. Mains chokes and the assignment

to M-MAX

frequency inverters are explained in the appendix.

In the project planning for the connection of frequency inverters to AC power networks with undefined circumstances, consider using main chokes.

Safety and switching

Fuses and cable cross-sections

The fuses and wire cross-sections allocated for power-side connections depend on the rated mains current I frequency inverter (without mains reactor).

Caution!

When selecting the cable cross-section, take the voltage drop under load conditions into account. The consideration of other standards (e.g. VDE 0113 or VDE 0289) is the responsibility of the user.

The recommended fuses and their assignment to the frequency inverters are listed in page 157 the appendix.

The national and regional standards (for example VDE 0113, EN

60204) must be observed and the necessary approvals (for example UL) at the site of installation must be fulfilled.

When the device is operated in a UL-approved system, use only UL-approved fuses, fuse bases and cables.

The leakage currents to ground (to EN 50178) are greater than

3.5 mA. The connection terminals marked PE and the housing must be connected with the ground circuit.

The leakage currents for the individual performance variables are listed in the appendix on page 147 ff.

of the

Residual current circuit breakers protect persons and animals from the existence (not the origination) of impermissibly high contact voltages. The prevent dangerous, in cases deadly injuries caused by electrical accidents and also serve as fire prevention.

Warning!

With frequency inverters, only AC/DC sensitive residual current circuit breakers (RCD type B) are to be used (EN 50178, IEC 755).

Identification on the residual-current circuit-breakers

AC/DC sensitive (RCD, type B)

Frequency inverters work internally with rectified AC currents. If an error occurs, the DC currents can block an RCD circuit breaker of type A from triggering and therefore disable the protective functionality.

Caution!

Debounced inputs may not be used in the safety circuit diagram.

Residual current circuit breakers (RCD) are only to be installed between the AC power supply network and the frequency inverter.

Safety-relevant leakage currents can occur while handling and when operating the frequency inverter, if the frequency inverter is not grounded (because of a fault).

Caution!

The specified minimum PE conductor cross-sections (EN 50178, VDE 0160) must be maintained.

Choose the cross-section of the PE conductor in the motor

lines at least as large as the cross-section of the phase lines (U, V, W).

Cables and fuses

The cross-sections of the cables and line protection fuses used must correspond with local standards.

For an installation in accordance with UL guidelines, the fuses and copper cable that are UL-approved and have a heat-resistance of +60/75 °C are to be used.

Use power cables with insulation according to the specified mains voltages for the permanent installation. A shielded cable is not required on the mains side.

A completely (360°) shielded low impedance cable on the motor side is required. The length of the motor cable depends on the RFI class and must not exceed 30 m for the M-Max

Residual-current device (RCD)

Leakage currents to ground are mainly caused by foreign capacities with frequency inverters; between the motor phases and the shielding of the motor cable and via the Y-capacitors of the noise filter. The size of the leakage current is mainly dependent upon the:

• length of the motor cable,

• shielding of the motor cable,

• height of the pulse frequency (switching frequency of the inverter),

• design of the noise filter,

• Grounding measures at the site of the motor.

The leakage current to ground is greater than 3.5 mA with

a frequency inverter. Based on the requirements of EN 50178, an increased ground (PE) has to be connected. The cable cross-section must be at least 10 mm consist of two separately connected ground cables.

As long as you use residual current circuit breakers, they

must be suitable for:

• the protection of installations with DC current component in case of fault scenario (RCD type B),

• high leakage currents (300 mA),

• brief discharges of pulse current spikes.
