Safety Information

• This equipment must be grounded for safe and proper operation.

• Do not supply power to a faulty inverter. If you find that the inverter is faulty, disconnect the

power supply and have the inverter professionally repaired.

• The inverter becomes hot during operation. Avoid touching the inverter until it has cooled to avoid burns.

• Do not allow foreign objects, such as screws, metal chips, debris, water, or oil, to get inside the inverter. Allowing foreign objects inside the inverter may cause the inverter to malfunction or result in a fire.

• Do not operate the inverter with wet hands. Doing so may result in electric shock.

• Do not modify the interior workings of the inverter. Doing so will void the warranty.

• Do not use cables with damages or cracks on the protective insulation when wiring the inverter.

Damaged insulation may cause misoperation, an electric shock or a fire.

• Do not place heavy objects on top of electric cables. Doing so may damage the cable and result in an electric shock.

Note

The maximum allowed prospective short-circuit current at the input power connection is defined in IEC 60439-1 as 100 kA. The drive is suitable for use in a circuit capable of delivering not more than

100 kA RMS at the drive’s maximum rated voltage.

• Do not transport the inverter by lifting with the inverter’s covers or plastic surfaces. The inverter

may tip over if covers break, causing injuries or damage to the product. Always support the inverter using the metal frames when moving it.

• Hi-capacity inverters are very heavy and bulky. Use an appropriate transport method that is suitable for the weight. Do not place heavy objects on top of electric cables. Doing so may damage the cable and result in an electric shock.

• Do not install the inverter on the floor or mount it sideways against a wall. The inverter must be installed vertically, on a wall or inside a panel, with its rear flat on the mounting surface.

3 Installing the Inverter

3.1 Installation Considerations

Inverters are composed of various precision electronic devices, and therefore the installation environment can significantly impact the lifespan and reliability of the product. The table below details the ideal operation and installation conditions for the inverter.

* The ambient temperature is the temperature measured at a point 2” (5 cm) from the surface of the

inverter. No ice or frost should be present.

Installing the Inverter

Installing

the Inverter

17

Do not allow the ambient temperature to exceed the allowable range while operating the inverter.

3.2 Selecting and Preparing a Site for Installation

When selecting an installation location, consider the following requirements:

• The inverter must be installed on a wall that can support the inverter’s weight.

• The location must be free from vibration. Vibrations can adversely affect the operation of

the inverter.

• The inverter can become very hot during operation. Install the inverter on a surface that is fire resistant or flame retardant with sufficient clearance around the inverter to allow for air circulation. The illustrations below detail the required installation clearances.

Installing the Inverter

18

Install the inverter on a non-flammable surface, and do not place flammable material near the inverter. Otherwise, a fire may result.

Note

Model types with capacities of 30 kW or more require a minimum of 8” clearance above and below the unit.

Installing the Inverter

Installing

the Inverter

19

Note

In order to meet EMC standards, 200 V, 30–75 kW model types and model types with capacities of 90 kW or more should be installed inside a metal cabinet.

• Ensure that the cable conduits do not obstruct the air flow to and from the cooling fan.

• Ensure sufficient air circulation is provided around the inverter when it is installed. If the

inverter is to be installed inside a panel, enclosure, or cabinet rack, carefully consider the position of the inverter’s cooling fan and vents. The cooling fan must be positioned to efficiently dissipate the heat generated by the operation of the inverter.

Installing the Inverter

20

• If you are installing multiple inverters of different ratings, provide sufficient clearance to meet the clearance specifications of the larger inverter. The iS7 inverters rated for up to 30 kW may be installed side by side.

Do not activate the EMC filter if the inverter uses a power source with an asymmetrical grounding structure, for example a grounded delta connection. Personal injury or death by electric shock may result if the power source is not grounded properly.

4.2 Activating and Deactivating the Built-in EMC Filter

Some iS-7 inverter models have built-in EMC filters to reduce conductive and radiational noise at the inverter input. Refer to 1.1.1 Identifying the Product on page 1 and check your inverter’s model type and specifications to see if it has a built-in EMC filter. If your inverter has a built-in EMC filter, refer to the following instructions to activate or deactivate it.

4.2.1 Up to 7.5 kW Inverters

1 Locate the plastic knockout cap that covers the EMC filter switch (jumper SW1).

2 Remove the knockout cap and locate the jumper switch. The EMC filter will be deactivated

if the two jumper pins are not connected.

1 Locate the EMC filter cable and the ground terminal at the bottom of the inverter.

The EMC filter is deactivated if the EMC filter cable is connected to the insulated stud.

2 Remove the EMC filter cable from the insulated stud and connect it to the ground terminal

An EMC filter prevents electromagnetic interference by reducing radio emissions from the inverter. Using an EMC filter is not always recommended, as it increases current leakage. If an inverter uses a power source with an asymmetrical grounding connection, the EMC filter must be turned off.

Before using the inverter, confirm the power supply’s grounding system. Disable the EMC filter

if the power source has an asymmetrical grounding connection.

• Do not connect power to the inverter until installation has been fully completed and the inverter is ready to be operated. Doing so may result in electric shock.

• Wiring and inspection of wiring must be performed by an authorized engineer.

• Install the inverter before connecting the cables.

• Ensure that no metal debris, such as wire clippings, remain inside the inverter. Metal debris in

the inverter can cause inverter failure.

• Power supply cables must be connected to the R, S, and T terminals. Connecting power cables to other terminals will damage the inverter.

• Use insulated ring lugs when connecting cables to R/S/T and U/V/W terminals.

• The inverter’s power terminal connections can cause harmonics that may interfere with other

communication devices located near the inverter. To reduce interference, the installation of noise filters or line filters may be required.

• To avoid circuit interruption or damaging connected equipment, do not install phase-advanced condensers, surge protection, or electronic noise filters on the output side of the inverter.

• To avoid circuit interruption or damaging connected equipment, do not install magnetic contactors on the output side of the inverter.

• Make sure that the total cable length does not exceed 495 ft (150 m). For inverters < = 3.7 kW capacity, ensure that the total cable length does not exceed 165 ft (50 m). Long cable runs can cause reduced motor torque in low frequency applications due to voltage drop. Long cable runs also increase a circuit’s susceptibility to stray capacitance and may trigger over-current protection devices or result in the malfunction of equipment connected to the inverter.

• Route the signal cables away from the power cables. Otherwise, signal errors may occur due to electric interference.

• Tighten terminal screws to their specified torques. Loose terminal block screws may allow the cables to disconnect and cause a short circuit or inverter failure. Refer to 4.7 Specifications of the Power Terminal Block and Exterior Fuse on page 6565 for torque specifications.

• Do not place heavy objects on top of electric cables. Heavy objects may damage the cable and result in electric shock.

• Use cables with the largest cross-sectional area, appropriate for power terminal wiring, to ensure that voltage drops do not exceed 2%.

• Use copper cables rated at 600 V, 75℃ for power terminal wiring.

• Use copper cables rated at 300 V, 75℃ for control terminal wiring.

• If you need to rewire the terminals due to wiring-related faults, ensure that the inverter keypad

display is turned off and the charge lamp under the terminal cover is off before working on wiring connections. The inverter may hold a high-voltage electric charge long after the power supply has been turned off.

4.3 Precautions for Wiring the Inverter

Connecting the Cables

Connecting

the Cables

57

Install ground connections for the inverter and the motor by following the correct specifications to ensure safe and accurate operation. Using the inverter and the motor without the specified grounding connections may result in electric shock.

• Do not use the ground terminal as the signal (control) ground.

• Do not share the ground connection with other machines that consume a large amount of

power, such as a welding machine.

• Connect the ground cable to the nearest earth contact and keep the cable length as short as possible.

Note

• 200 V products require Class 3 grounding. Resistance to ground must be ≤ 100 Ω.

• 400 V products require Special Class 3 grounding. Resistance to ground must be ≤ 10 Ω.

1) Apply rated torques to the terminal screws. Loose screws may cause the terminals to short circuit

and malfunction.

2) Only use copper wires with a 600 V, 75℃ rating for the power terminal wiring.

4.7.1 Cable Length between the Inverter and the Motor

The maximum cable lengths of the inverter and the motor are listed in <Table 1) Maximum cable length by inverter capacity>.

Make sure that the total cable length does not exceed 495 ft (150 m). For inverters with a capacity of less than 3.7 kW, ensure that the total cable length does not exceed 165 ft (50 m). Long cable runs can cause reduced motor torque in low frequency applications due to voltage

drop. Long cable runs also increase a circuit’s susceptibility to stray capacitance and may

trigger over-current protection devices, or result in the malfunction of equipment connected to the inverter.

The following table lists maximum carrier frequencies available for model types with a rated capacity of 5.5 kW or more.

Depending on the system layout and operating conditions at the installation site, high peak output voltage may result.

Connecting the Cables

Connecting

the Cables

67

a) If the output peak voltage is too high even when the motor cable length is shorter than the maximum recommended cable length for the inverter capacity:

- use a motor with a high insulation rating.

- install an output circuit filter (micro surge filter).

- install a dv/dt filter, or a sine wave filter.

b) If the cable length is too long:

- use thicker cables to prevent voltage drop. [Voltage Drop (V) = [√3 X cable resistance (mΩ/m) X cable length (m) X current (A)] / 1000]

- do not use 3-core cables.

- use a lower carrier frequency.

4.7.2 Protective Measures for the Inverter and the Motor

The inverter output voltage pulse, regardless of the actual output frequency, is identical to the DC link voltage pulse, which has a very short rising time. When the power is transmitted through the output cables, the output peak voltage can rise up to twice the total DC link voltage (2.8 times the main power voltage).

If a switching device (a magnetic contactor or relay) is connected to the output side of the inverter, high-voltage surges may result whenever a switch is made, regardless of the length of the motor cable.

Such high-voltage surges can damage the inverter’s output components (such as the current sensor), motor cables, and the motor itself. To protect the inverter and the motor from such damage caused by a high-voltage surge, do not install switching devices in the output side of the inverter. You can install an output reactor, dv/dt filter, or sine wave filter to protect the inverter and motor from a surge voltage.

An output surge with a high switching frequency and fast rising time causes a motor shaft current that runs through the motor bearing. It slowly corrodes the surface of the motor bearing, eventually seizing up the motor.

To decrease the motor shaft current and protect the motor insulation, refer to <Table 1) Maximum cable length by inverter capacity>. Install a dv/dt filter or sine wave filter if possible, regardless of the length of the motor cable.

Note

When you use the analog voltage input, the bipolar input range (-10 – +10V), in comparison to the unipolar input range (0–10V), allows for more accurate input control with smaller increments.

If the analog input is interrupted when setting a frequency reference using the analog voltage (V) input and no voltage input is received at the terminal, an offset voltage may be applied to keep the frequency reference at approximately 4–5 Hz.

4.12 Setting the Built-in Surge Filter

The iS7 series inverters have a built-in surge filter between the input phases and the ground connection to absorb and mitigate surge current. This filter consists of a Y-CAP and multiple varistors.

However, in a non-grounded power system where specific ground faults occur frequently, adequate measures are required to avoid inverter damage.

Refer to the following table for details on how to prevent damage to specific power systems.

*OSS / OSH may cause overcurrent when the load is too large or when the acceleration/deceleration time is short. The inverter monitors the output current so that an overcurrent trip does not occur and also performs overcurrent suppression. At this time, the output frequency is automatically changed to reduce the output current or the inverter output is temporarily cut off to prevent overcurrent.

Description

Monitor mode

MON

Displays the inverter’s operation status information. You can monitor the frequency setting, operating frequency display, output current, voltage, etc.

Parameter mode

PAR

Used to configure the functions required to operate the inverter. These functions are divided into 12 groups based on purpose and complexity.

User & Macro mode

U&M

Used to define User and Macro groups. These user-definable groups allow specific functions of the inverter to be grouped and managed in separate groups. This mode will not be displayed when navigating through modes if no User groups or Macro groups have been defined.

Trip mode

TRP

Used to monitor the inverter’s fault trip information, including the

previous fault trip history. When a fault trip occurs during inverter operation, the operation frequency, output current, and output voltage of the inverter at the time of the fault can be monitored. This mode will not be displayed if the inverter is not at fault and a fault trip history does not exist.

Configuration mode

CNF

Used to configure the inverter features that are not directly related to the operation of the inverter. The settings you can configure in Configuration mode include keypad display language options, monitor mode environment settings, communication module display settings, and parameter duplication and initialization.
