2.1 Peripheral devices

2.1.1 Inverter and peripheral devices

• To prevent an electric shock, always earth (ground) the motor, the inverter, and the converter unit.

• Do not install a power factor correction capacitor or surge suppressor or capacitor type filter on the inverter's output side. Doing so will cause the inverter to be shut off or the capacitor and surge suppressor to be damaged. If any of the above devices is connected, immediately remove it. When installing a molded case circuit breaker on the output side of the inverter, contact the manufacturer of the molded case circuit breaker.

• Electromagnetic wave interference The input/output (main circuit) of the inverter or the converter unit includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter or the converter unit. In this case, activating the EMC filter of the converter unit may minimize interference. (Refer to page 62.)

• For details of options and peripheral devices, refer to the respective Instruction Manual.

• A PM motor cannot be driven by the commercial power supply.

• A PM motor is a motor with permanent magnets embedded inside. High voltage is generated at the motor terminals while the motor is running. Before closing the contactor at the output side, make sure that the inverter power is ON and the motor is stopped.

Must be selected carefully since an inrush current flows in the converter unit at power ON.

Install this to ensure safety. Do not use this to start and stop the inverter. Doing so will shorten the life of the inverter and the converter unit.

Install this to suppress harmonics and to improve the power factor. An AC reactor (FR-HAL) (option) is required when installing the inverter near a large power supply system (1000 kVA or more). Under such condition, the inverter and the converter unit may be damaged if you do not use a reactor. Select a reactor according to the applied motor capacity.

Suppresses the noise radiated from the power supply side of the converter unit.

Suppresses the power supply harmonics significantly. Install these options as required. When FR-HC2 is used, FR-CC2 is not required.

Allows the inverter to provide the optimal regenerative braking capability. Install these options as required.

Connect between the inverter and a personal computer with a USB (ver.

1.1) cable. Use a USB memory device to copy parameter settings or use the trace function.

Install this to reduce the electromagnetic noise generated from the inverter and the converter unit. The noise filter is effective in the range from about

0.5 to 5 MHz.

Connect this for an application where a PM motor is driven by the load even while the inverter power is OFF. Do not open or close the contactor while the inverter is running (outputting).

A PM motor can be used. A PM motor cannot be driven by the commercial power supply.

2.3 Installation of the inverter and enclosure design

When designing or manufacturing an inverter enclosure, determine the structure, size, and device layout of the enclosure by

fully considering the conditions such as heat generation of the contained devices and the operating environment. An inverter

uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter in the

ambient environment that completely satisfies the equipment specifications.

2.3.1 Inverter installation environment

The following table lists the standard specifications of the inverter installation environment. Using the inverter in an environment that does not satisfy the conditions deteriorates the performance, shortens the life, and causes a failure. Refer to the following points, and take adequate measures.

Standard environmental specifications of the inverter

or less at 10 to 55 Hz (directions of X, Y, Z axes)

 Temperature applicable for a short time, for example, in transit.  For the installation at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude.

Temperatur e

The permissible surrounding air temperature of the inverter is between -10°C and +50°C (-10°C and +40°C at the SLD rating). Always operate the inverter within this temperature range. Operation outside this range will considerably shorten the service lives of the semiconductors, parts, capacitors and others. Take the following measures to keep the surrounding air temperature of the inverter within the specified range. (a) Measures against high temperature

• Use a forced ventilation system or similar cooling system. (Refer to page 20.)

• Install the enclosure in an air-conditioned electric chamber.

• Block direct sunlight.

• Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.

• Ventilate the area around the enclosure well. (b) Measures against low temperature

• Provide a space heater in the enclosure.

• Do not power OFF the inverter. (Keep the start signal of the inverter OFF.) (c) Sudden temperature changes

• Select an installation place where temperature does not change suddenly.

• Avoid installing the inverter near the air outlet of an air conditioner.

• If temperature changes are caused by opening/closing of a door, install the inverter away from the door.

NOTE

Humidity

Operate the inverter within the ambient air humidity of usually 45 to 90% (up to 95% with circuit board coating). Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may cause a spatial electrical breakdown. The humidity conditions for the insulation distance defined in JEM 1103 standard "Insulation Distance from Control Equipment" is 45 to 85%.

• For the amount of heat generated by the inverter unit, refer to page 19.

INSTALLATION AND WIRING

Installation of the inverter and enclosure design

(a) Measures against high humidity

• Make the enclosure enclosed, and provide it with a hygroscopic agent.

• Provide dry air into the enclosure from outside.

• Provide a space heater in the enclosure.

(b) Measures against low humidity

Air with proper humidity can be blown into the enclosure from outside. Also when installing or inspecting the unit, discharge

your body (static electricity) beforehand, and keep your body away from the parts and patterns.

Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside air

temperature changes suddenly.

Condensation causes such faults as reduced insulation and corrosion.

• Take the measures against high humidity in (a).

• Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)

Dust, dirt, oil mist

Dust and dirt will cause such faults as poor contacts, reduced insulation and cooling effect due to the moisture-absorbed

accumulated dust and dirt, and in-enclosure temperature rise due to a clogged filter. In an atmosphere where conductive

powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time.

Since oil mist will cause similar conditions, it is necessary to take adequate measures.

Precautions

• Place the inverter in a totally enclosed enclosure.

Take measures if the in-enclosure temperature rises. (Refer to page 20.)

• Purge air.

Pump clean air from outside to make the in-enclosure air pressure higher than the outside air pressure.

Corrosive gas, salt damage

If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the

relays and switches will result in poor contact.

In such places, take the measures given above.

Explosive, flammable gases

As the inverter is non-explosion proof, it must be contained in an explosion-proof enclosure. In places where explosion may

be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and

has passed the specified tests. This makes the enclosure itself expensive (including the test charges). The best way is to

avoid installation in such places and install the inverter in a non-hazardous place.

High altitude

Use the inverter at an altitude of within 2500 m. For use at an altitude above 1000 m, consider a 3% reduction in the rated

current per 500 m increase in altitude.

If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric

strength.

Vibration, impact

The vibration resistance of the inverter is up to 2.9 m/s2 at 10 to 55 Hz frequency and 1 mm amplitude for the directions of X,

Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and cause poor contacts of connectors,

even if those vibration and impacts are within the specified values.

Especially when impacts are applied repeatedly, caution must be taken because such impacts may break the installation feet.

Precautions

• Provide the enclosure with rubber vibration isolators.

• Strengthen the structure to prevent the enclosure from resonance.

• Install the enclosure away from the sources of the vibration.

2.3.3 Cooling system types for inverter enclosure

From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors,

etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the

permissible temperatures of the in-enclosure equipment including the inverter.

The cooling systems are classified as follows in terms of the cooling calculation method.

(a) Cooling by natural heat dissipation from the enclosure surface (totally enclosed type)

(b) Cooling by heat sink (aluminum fin, etc.)

(d) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)

This system is low in cost and generally used, but the enclosure size increases as the inverter capacity increases. This system is for relatively small capacities.

Being a totally enclosed type, this system is the most appropriate for hostile environment having dust, dirt, oil mist, etc. The enclosure size increases depending on the inverter capacity.

This system has restrictions on the heat sink mounting position and area. This system is for relatively small capacities.

This system is for general indoor installation. This is appropriate for enclosure downsizing and cost reduction, and often used.

• To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, keep the

cables of the main circuit for input and output separated.

• After wiring, wire offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.

When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the

inverter.

• Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.

Connection between the converter unit and the inverter

Perform wiring so that the commands sent from the converter unit are transmitted to the inverter without fail. Incorrect

connection may damage the converter unit and the inverter.
