• Though FRENIC-Eco is manufactured under strict quality control, install safety devices for applications where serious accidents or material losses are foreseen in relation to the failure of it.

An accident could occur.

Installation

• Install the inverter on a nonflammable material such as metal.

Otherwise fire could occur.

• Do not place flammable matter nearby.

Doing so could cause fire.

• Do not support the inverter by its terminal block cover during transportation.

Doing so could cause a drop of the inverter and injuries.

• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink.

Otherwise, a fire or an accident might result.

• Do not install or operate an inverter that is damaged or lacking parts.

Doing so could cause fire, an accident or injuries.

• Do not get on a shipping box.

• Do not stack shipping boxes higher than the indicated information printed on those boxes.

Doing so could cause injuries.

Wiring

• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/a ground fault circuit interrupter(GFCI)(with overcurrent protection) in the path of power lines. Use the devices within the recommended current range.

• Use wires in the specified size.

Otherwise, fire could occur.

• Do not use one multicore cable in order to connect several inverters with motors.

• Do not connect a surge suppressor to the inverter's output (secondary) circuit.

Doing so could cause fire.

GENERAL PRECAUTIONS

Drawings in this manual may be illustrated without covers or safety shields for explanation of detail parts. Restore the covers and shields in the original state and observe the description in the manual before starting operation.

Conformity with Low Voltage Directive in the EU

If installed according to the guidelines given below, inverters marked with CE can be considered to be compliant with the Low Voltage Directive 73/23/EEC.

1. Be sure to earth the grounding terminal zG. Use an earth wire sized more than that of the power wires

used in the power dispatch system. Do not use a residual-current-operated protective device (RCD)* or a ground fault circuit interrupter(GFCI)* as a sole mechanism of electric shock protection.

*With overcurrent protection.

2. Use an MCCB, RCD/GFCI or MC in conformity with EN or IEC standards.

3. When an RCD/GFCI is used for protection of electric shock caused by a direct or indirect contact to the live parts, insert a type B RCD/GFCI in input lines (primary) of the inverter for the 3-phase 208 V or 460 V power source.

4. Use inverters in an environment that does not exceed pollution degree 2. If inverters are to be used in an environment with pollution degree 3 or 4, place them in an enclosure of IP54 or above.

5. To protect human body from an electric shock caused by a contact to live parts, install inverters, AC reactor and input /output filter in the enclosure of IP2X. In the case where human body easily contacts to live parts, a top panel of the enclosure should be IP4X or higher.

6. Do not directly connect a copper wire to the grounding terminal. Use a crimp terminal with tin or equivalent plating to connect the earth wire.

7. When using inverters at an altitude of more than 6600ft(2000 m), note that the basic insulation applies to the insulation degree of the control circuitry. At an altitude of more than 9800ft(3000 m), inverters cannot be used.

Conformity with Low Voltage Directive in the EU (continued)

8. Use the wires listed in EN60204-1.

Installation location

When driving a 460V general-purpose motor with an inverter using extremely long wires, damage to the insulation of the motor may occur. Use an output circuit filter (OFL) if necessary after checking with the motor manufacturer. Fuji motors do not require the use of output circuit filters because of their reinforced insulation.

When the inverter is used to run a general-purpose motor, the temperature of the motor becomes higher than when it is operated using a commercial power supply. In the low-speed range, the cooling effect will be weakened, so decrease the output torque of the motor.

When an inverter-driven motor is mounted to a machine, resonance may be caused by the natural frequencies of the machine system.

Note that operation of a 2-pole motor at 60 Hz or higher may cause abnormal vibration.

* The use of a rubber coupling or vibration dampening rubber is

recommended.

* Use the inverter's jump frequency control feature to skip the resonance

frequency zone(s).

When an inverter is used with a general-purpose motor, the motor noise level is higher than that with a commercial power supply. To reduce noise, raise carrier frequency of the inverter. Operation at 60 Hz or higher can also result in higher noise level.

When driving an explosion-proof motor with an inverter, use a combination of a motor and an inverter that has been approved in advance.

These motors have a larger rated current than general-purpose motors. Select an inverter whose rated output current is greater than that of the motor.

These motors differ from general-purpose motors in thermal characteristics. Set a low value in the thermal time constant of the motor when setting the electronic thermal function.

For motors equipped with parallel-connected brakes, their braking power must be supplied from the primary circuit. If the brake power is connected to the inverter's output circuit by mistake, the brake will not work.

Do not use inverters for driving motors equipped with series-connected brakes.

If the power transmission mechanism uses an oil-lubricated gearbox or speed changer/reducer, then continuous motor operation at low speed may cause poor lubrication. Avoid such operation.

It is necessary to take special measures suitable for this motor type. Contact your Fuji Electric representative for details.

Single-phase motors are not suitable for inverter-driven variable speed operation. Use three-phase motors.

Use the inverter within the ambient temperature range from -10 to +50°C (14 to 122

°F).

The heat sink of the inverter may become hot under certain operating conditions, so install the inverter on nonflammable material such as metal.

Ensure that the installation location meets the environmental conditions specified in Chapter 2, Section 2.1 "Operating Environment."

Combination with peripheral devices

Wiring

Installing an MCCB or RCD/GFCI

Installing an MC in the secondary circuit

Installing an MC in the primary circuit

Install a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/a ground fault circuit interrupter (GFCI) (with overcurrent protection) in the primary circuit of the inverter to protect the wiring. Ensure that the circuit breaker rated current is equivalent to or lower than the recommended rated current.

If a magnetic contactor (MC) is mounted in the inverter's output (secondary) circuit for switching the motor to commercial power or for any other purpose, ensure that both the inverter and the motor are completely stopped before you turn the MC ON or OFF.

Remove the magnet contactor (MC) already installed and built-in surge suppressor from the inverter's output (secondary) circuit before installing the MC to switch the motor power.

Do not turn the magnetic contactor (MC) in the primary circuit ON or OFF more than once an hour as an inverter failure may result.

If frequent starts or stops are required during motor operation, use (FWD)/(REV) signals or the RUN/STOP key.

The electronic thermal function of the inverter can protect the motor. The operation level and the motor type (general-purpose motor, inverter motor) should be set. For high-speed motors or water-cooled motors, set a small

value for the thermal time constant and protect the motor.

If you connect the motor thermal relay to the motor with a long wire, a high-frequency current may flow into the wiring stray capacitance. This may cause the relay to trip at a current lower than the set value for the thermal relay. If this happens, lower the carrier frequency or use the output circuit filter (OFL).

Do not mount power-factor correcting capacitors in the inverter’s primary circuit. (Use the DC reactor to improve the inverter power factor.) Do not use power-factor correcting capacitors in the inverter’s output (secondary) circuit. An overcurrent trip will occur, disabling motor operation.

Do not connect a surge suppressor to the inverter's output (secondary) circuit.

Use of a filter and shielded wires is typically recommended to satisfy EMC Directives.

If an overvoltage trip occurs while the inverter is stopped or operated under

a light load, it is assumed that the surge current is generated by open/close of the power-factor correcting capacitor in the power system.

* Connect a DC reactor to the inverter.

Megger test

When checking the insulation resistance of the inverter, use a 500 V megger and follow the instructions contained in Chapter 7, Section 7.5 "Insulation Test."

Control circuit wiring length

Wiring length between inverter and motor

When using remote control, limit the wiring length between the inverter and operator box to 67ft (20m) or less and use twisted pair or shielded wire.

If long wiring is used between the inverter and the motor, the inverter will overheat or trip as a result of overcurrent (high-frequency current flowing into the stray capacitance) in the wires connected to the phases. Ensure that the wiring is shorter than 164ft (50m). If this length must be exceeded, lower the carrier frequency or mount an output circuit filter (OFL).

Wiring size

Wiring type

Select wires with a sufficient capacity by referring to the current value or recommended wire size.

When several inverters drive motors, do not use one multicore cable in order to connect several inverters with motors.

Grounding Securely ground the inverter using the grounding terminal.

Selecting inverter capacity

Transportation and storage

1.3 Transportation

• When carrying an inverter, always support its bottom at the front and rear sides with both hands. Do not hold covers or individual parts only. You may drop the inverter or break it.

• When hoisting an inverter with hoisting holes, hook or rope the 4 holes evenly.

1.4 Storage Environment

1.4.1 Temporary storage

Store the inverter in an environment that satisfies the requirements listed in Table 1.1.

Table 1.1 Environmental Requirements for Storage and Transportation

Item Requirements

Storage temperature *1-25 to +70°C(-13° to 158°F) Relative humidity 5 to 95% *2

Atmosphere The inverter must not be exposed to dust, direct sunlight, corrosive or flammable gases, oil

Assuming a comparatively short storage period (e.g., during transportation or the like).

Even if the humidity is within the specified requirements, avoid such places where the inverter will be subjected to

sudden changes in temperature that will cause condensation to form.

mist, vapor, water drops or vibration. The atmosphere must contain only a low level of salt. (0.01 mg/cm

86 to 106 kPa (in storage) Atmospheric pressure

70 to 106 kPa (during transportation)

or less per year)

Precautions for temporary storage

(1) Do not leave the inverter directly on the floor.

(2) If the environment does not satisfy the specified requirements, wrap the inverter in an airtight vinyl sheet or

the like for storage.

(3) If the inverter is to be stored in an environment with a high level of humidity, put a drying agent (such as silica

gel) in the airtight package described in item (2).

1.4.2 Long-term storage

The long-term storage methods for the inverter vary largely according to the environment of the storage site. General storage methods are described below.

(1) The storage site must satisfy the requirements specified for temporary storage. However, for storage exceeding three months, the ambient temperature should be within the range from -10

to +30 °C(14 to 56°F). This is to prevent the electrolytic capacitors in the inverter from deteriorating.

(2) The inverter must be stored in a package that is airtight to protect it from moisture. Include a drying agent

inside the package to maintain the relative humidity inside the package to within 70%.

(3) If the inverter has been installed in the equipment or control board at a construction site where it may be

subjected to humidity, dust or dirt, then remove the inverter and store it in a suitable environment specified in Table 1.1.

Precautions for storage over 1 year

If the inverter will not be powered on for a long time, the property of the electrolytic capacitors may deteriorate. Power the inverters on once a year and keep them on for 30 to 60 minutes. Do not connect the inverters to motors or run the motor.

A location where the inverter is not subject to abrupt changes in temperature that would result in the formation of condensation or ice.

2.2 Installing the Inverter

(1) Mounting base

The temperature of the heat sink will rise up to approx. 90°C during operation of the inverter, so the inverter should be mounted on a base made of material that can withstand temperatures of this level.

Table 2.2 Output Current Derating Factor in

Relation to Altitude

Altitude

3300ft(1000m) or lower 1.00

3300ft(1000m) to 4900ft(1500m) 0.97

4900ft(1500m) to 6600ft(2000m) 0.95

6600ft(2000m) to 8200ft(2500m) 0.91

8200ft(2500m) to 9800ft(3000m) 0.88

(Note 1) When inverters are mounted side-by-side without any gap between them (5HP for 208V, 7.5HP for 460HP or below), the ambient temperature should be within the range from -10 to +40°C(14 to 104°F).

(Note 2) Do not install the inverter in an environment where it may be exposed to cotton waste or moist dust or dirt which will clog the heat sink in the inverter. If the inverter is to be used in such an environment, install it in the enclosure o your system or other dustproof containers.

(Note 3) If you use the inverter in an altitude above 3300ft(1000m), you should apply an output current derating factor as listed in Table 2.2.

Output current

factor

Install the inverter on a base constructed from metal or other non-flammable material.

A fire may result with other material.

(2) Clearances

Ensure that the minimum clearances indicated in Figure 2.1 are maintained at all times. When installing the inverter in the enclosure of your system, take extra care with ventilation inside the enclosure as the temperature around the inverter will tend to increase. Do not install the inverter in a small enclosure with poor ventilation.

2-1

* 2.0inch(50mm) for models

of 460 V series 125HP or above

Figure 2.1 Mounting Direction and

Required Clearances

 When mounting two or more inverters

Horizontal layout is recommended when two or more inverters are to be installed in the same unit or enclosure. If it is necessary to mount the inverters vertically, install a partition plate or the like between the inverters so that any heat radiating from an inverter will not affect the one/s above. As long as the ambient temperature is 40°C(104°F)or lower, inverters can be mounted side-by-side without any gap between them (only for inverters with a capacity of 5HP fo 208V, 7.5HP for 460V or below).

 When employing external cooling

At the shipment time, the inverter is set up for mount inside your equipment or enclosure so that cooling is done all internally.

To improve cooling efficiently, you can take the heat sink out of the equipment or the enclosure (as shown on the right) so that cooling is done both internally and externally (this is called "external cooling").

In external cooling, the heat sink, which dissipates about 70% of the total heat (total loss) generated into air, is situated outside the equipment or the enclosure. As a result, much less heat is radiated inside the equipment or the enclosure.

To take advantage of external cooling, you need to use the external cooling attachment option for inverters with a capacity of 30HP for 208V, 40HP for 460V or below, or simply re-position the mounting bases for the cooling unit for inverters with a capacity of 40HP for 208V, 50HP for 460V or above.

In an environment with high humidity or a lot of fibrous dust, however, do not use external cooling in an environment with high humidity or a lot of fibrous dust, which tends to clog the heat sink.

 For details, refer to the Mounting Adapter for External

Cooling "PB-F1" Installation Manual and FRENIC-Eco User’s Manual.

Figure 2.2 External Cooling

Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink.

This may result in a fire or accident.

2-2

To utilize external cooling for inverters with a capacity of 40HP for 208V, 50HP for 460V or above, change the position of the top and bottom mounting bases from the edge to the center of the inverter as illustrated in Figure

2.3.

Screws differ in size, length and count for each inverter. Be sure to refer to the table below.

2) Secure the top mounting base to the center of the inverter with the base fixing screws, using case fixing screw holes.

3) Secure the bottom mounting base to the center of the inverter with the base fixing screws.

For models shown in Figure B

1) Remove all of the base fixing screws from the top and bottom of the inverter. Also remove the case fixing screws.

2) Secure the top mounting base to the center of the inverter with the base fixing screws, using case fixing screw holes. Set the removed case fixing screws to the screw holes where the top mounting bases were secured.

3) In the same way, secure the bottom mounting base to the center of the inverter.

Figure B

Figure 2.3 Relocating the Top and Bottom Mounting Bases

When moving the top and bottom mounting bases, use only the specified screws.

A fire or an accident may be caused.

2-4

(3) Mounting direction

Mount the inverter vertically to the mounting surface and fix it securely with four screws or bolts so that the logo "FRENIC-Eco" can be seen from the front.

Do not mount the inverter upside down or horizontally. Doing so will reduce the heat dissipation efficiency of the inverter and cause the overheat protection function to operate, so the inverter will no run.

(4) Solving abnormal vibration after installation

If any vibration in the surroundings reaches the inverter and causes abnormal vibration to the cooling fan(s) or the keypad, fix them firmly using the fixing screws provided as accessories.

2.3.5 Wiring precautions

Follow the rules below when performing wiring for the inverter.

(1) Make sure that the source voltage is within the rated voltage range specified on the nameplate. (2) Be sure to connect the three-phase power wires to the main circuit power input terminals L1/R, L2/S and

L3/T of the inverter. If the power wires are connected to other terminals, the inverter will be damaged when the power is turned on.

(3) Always connect the grounding terminal to prevent electric shock, fire or other disasters and to reduce

electric noise.

(4) Use crimp terminals covered with insulated sleeves for the main circuit terminal wiring to ensure a reliable

connection.

(5) Keep the power supply wiring (primary circuit) and motor wiring (secondary circuit) of the main circuit, and

control circuit wiring as far away as possible from each other.

• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or a ground fault circuit interrupter (GFCI) (with overcurrent protection) in the path of each pair of power lines to inverters. Use the devices recommended ones within the related current range.

• Use wires in the specified size.

• Tighten terminals with specified torque.

Otherwise, fire could occur.

• Do not connect a surge suppressor to the inverter's output circuit.

• Do not use one multicore cable in order to connect several inverters with motors.

Doing so could cause fire.

• Ground the inverter in compliance with the national or local electric code.

Otherwise, electric shock or fire could occur.

• Qualified electricians should carry out wiring.

• Be sure to perform wiring after turning the power off.

Otherwise, electric shock could occur.

• Be sure to perform wiring after installing the inverter.

Otherwise, electric shock or injuries could occur.

• Ensure that the number of input phases and the rated voltage of the product match the number of phases and the voltage of the AC power supply to which the product is to be connected.

• Do not connect the power source wires to output terminals (U, V, and W).

Doing so could cause fire or an accident.

Connect a DC reactor (DCR) for improving power factor (an option for the inverter whose capacity is 60HP for 208V, 75HP for 460V or below).

Connect a DC link bus of other inverter(s). An optional regenerative converter is also connectable to these terminals.

Normally, no need to use these terminals. Use these terminals for an auxiliary power input of the fans in a power system using a power regenerative PWM converter (RHC series).

Grounding terminals for the inverter’s chassis (or case) and motor. Earth one of the terminals and connect the grounding terminal of the motor. Inverters provide a pair of grounding terminals that function equivalently.

2-16

Grounding terminals ( G)

Be sure to ground either of the two grounding terminals for safety and noise reduction. The inverter is designed

to use with a safety grounding to avoid electric shock, fire and other disasters.

Grounding terminals should be grounded as follows:

1) Ground the inverter in compliance with the national or local electric code.

2) Use a thick grounding wire with a large surface area and keep the wiring length as short as possible.

Main circuit power terminals (L1/R, L2/S, L3/T)

1) Connect these terminals to the power supply via a molded-case circuit breaker or ground-leakage circuit breaker for circuit protection. Phase-sequence matching is unnecessary.

2) To insure safety, a magnetic contactor should be used to disconnect the drive from the power supply when the drive protective function activates.

3) Use control circuit terminal FWD/REV or the RUN/STOP key on the keypad panel to start or stop the drive. The main circuit power should be used to start or stop the drive only if absolutely necessary and then should not be used more than once every hour.

4) If you need to connect these terminals to a single-phase power supply, please contact the factory.

Drive output terminals (U, V, W)

1) Connect these terminals to a 3-phase motor in the correct phase sequence. If the direction of motor rotation is incorrect, exchange any two of the U, V, and W phases.

2) Do not connect a power factor correction capacitor or surge absorber to the drive output.

3) If the cable from the drive to the motor is very long, a high-frequency current may be generated by stray capacitance between the cables and result in an overcurrent trip of the drive, an increase in leakage current, or a reduction in current indication precision.

When a motor is driven by a PWM-type drive, the motor terminals may be subject to surge voltage generated by drive element switching. If the motor cable (with 460V series motors, in particular) is particularly long, surge voltage will deteriorate motor insulation. To prevent this, use the following guidelines:

Drives 7.5 HP and larger

Motor Insulation Level 1000V 1300V 1600V

460 VAC Input Voltage 66 ft (20 m) 328 ft (100 m) 1312 ft (400 m) *

208 VAC Input Voltage 1312 ft (400 m) * 1312 ft (400 m) * 1312 ft (400 m) *

Drives 5 HP and smaller

Motor Insulation Level 1000V 1300V 1600V

460 VAC Input Voltage 66 ft (20 m) 165 ft (50 m) * 165 ft (50 m) *

208 VAC Input Voltage 328 ft (100 m) * 328 ft (100 m) * 328 ft (100 m) *

* For this case the cable length is determined by secondary effects and not voltage spiking.

When a motor protective thermal O/L relay is inserted between the drive and the motor, the thermal O/L relay may malfunction (particularly in the 460V series), even when the cable length is 165 feet (50m) or less. To correct, insert a filter or reduce the carrier frequency. (Use function code “F26 Motor sound”.)

2-17

DC reactor terminals, P1 and P (+)

1) Remove the jumper bar from terminals P1 and P(+).

2) Connect a DC reactor (option) to terminals P1 and P(+).

• The wiring length should be 33ft(10 m) or below.

• Do not remove the jumper bar if a DC reactor is not going to be used.

• An inverter with a capacity of 75HP for 208V, 100HP for 460V or above is equipped with a DC reactor as standard. Be sure to connect the DC reactor except when an optional converter is connected to the inverter.

Switching connectors

 Power switching connectors (CN UX) (for the models of 460 V 75HP or above)

An inverter of 460 V 75HP or above is equipped with a set of switching connectors CU UX (male) which should be configured with a jumper according to the power source voltage and frequency. Set the jumper to U1 or U2 depending upon the power source voltage applied to the main power inputs (L1/R, L2/S, L3/T) or auxiliary power input terminals (R1, T1) for fans, as shown in Figure 2.16.

2-18

 Fan power supply switching connectors (CN R) and (CN W) (for models of 50HP or above (208 V) or 75HP or

above (460 V))

The standard FRENIC-Eco series of inverters also accept DC-linked power input in combination with a power regenerative PWM converter (RHC series). Even when you drive the inverter with a DC-linked power, however, you also need to supply AC power for models of 50HP or above (208 V) or 75HP or above (460 V), since it contains components such as AC fans that are driven by AC power. In this case, reinstall the connectors (CN R) and (CN W) to the NC and FAN positions respectively and supply the power to the auxiliary power input terminals (R1, T1).

For the actual procedure, refer to Figures 2.14 to 2.16 below.

On the fan power supply switching connectors (CN R) and (CN W), the jumpers are installed at FAN and NC positions respectively by factory default. Do not relocate the jumper unless you drive the inverter with a DC-linked power supply.

If there is a mistake in the installation of the jumpers for the switching connectors, the cooling fan will not run, causing a heat sink overheating alarm "

0h1

" or a charger circuit error alarm "

DC link bus terminals, P (+) and N (-)

These are provided for the DC link bus powered system. Connect these terminals with terminals P(+) and N (-) of other inverters.

Consult your Fuji Electric representative if these terminals are to be used.

Main circuit power input terminals, L1/R, L2/S, and L3/T (three-phase input)

1) For safety, make sure that the molded case circuit breaker (MCCB) or magnetic contactor (MC) is turned off before wiring the main circuit power input terminals.

2) Connect the main circuit power supply wires (L1/R, L2/S and L3/T) to the input terminals of the inverter via an MCCB or residual-current-operated protective device (RCD)/a ground fault circuit interrupter (GFCI)*, and MC if necessary.

It is not necessary to align phases of the power supply wires and the input terminals of the inverter with

each other.

* With overcurrent protection

It is recommended that a magnetic contactor be inserted that can be manually activated. This is to allow you to disconnect the inverter from the power supply in an emergency (e.g., when the protective function is activated) so as to prevent a failure or accident from causing the secondary problems.

Auxiliary power input terminals R0 and T0 for the control circuit

In general, the inverter will run normally without power supplied to the auxiliary power input for the control circuit. However, if you share the input power for the control circuit with that for the main circuit, you would be lost when, in the event of an error or alarm, you turn OFF the magnetic contactor between the inverter and the commercial power supply. If the magnetic contactor is turned OFF, the input power to the control circuit is shut OFF, causing the alarm signals (30A/B/C) to be lost and the display on the keypad to disappear. To secure input power to the control circuit at all times, supply the power from the primary side of the magnetic contactor to control power auxiliary input terminals R0 and T0.

When introducing a residual-current-operated protective device (RCD)/ground fault circuit interrupter (GFCI), connect its output (secondary) side to terminals R0 and T0. Connecting its input (primary) side to those terminals causes the RCD/GFCI to malfunction since the input power voltage to the inverter is three-phase but the one to terminals R0 and T0 is single-phase. To avoid such problems, be sure to insert an insulation transformer or auxiliary B contacts of a magnetic contactor in the location shown in Figure 2.17.

Ground fault circuit interrupter

Figure 2.17 Connection Example of residual-current-operated protective device (RCD)/

Ground Fault Circuit Interrupter (GFCI)

2-22

When connecting a PWM converter with an inverter, do not connect the power supply line directly to terminals R0 and T0. If a PWM is to be connected, insert an insulation transformer or auxiliary B contacts of a magnetic contactor at the power supply side.

For connection examples at the PWM converter side, refer to the PWM Converter Instruction Manual.

Ground fault circuit interrupter

Figure 2.18 Connection Example of PWM Converter

Auxiliary power input terminals R1 and T1 for the fan

Inverters, 208 V 50HP or above and 460 V 75HP or above are equipped with these terminals R1 and T1. Only if the inverter works with the DC link power input whose source is a power regenerative PWM converter (e.g. RHC series), these terminals are used to feed power to the fans while they are not used in any power system of ordinary configuration. The fan power is:

Single phase 200 to 220 VAC/50 Hz, 200 to 230 VAC/60 Hz for 208 V 50HP or above Single phase 380 to 440 VAC/50 Hz. 380 to 480 VAC/60 Hz for 460 V 75HP or above

2-23

2.3.7 Wiring for control circuit terminals

In general, sheaths and covers of the control signal cables and wires are not specifically designed to withstand a high electric field (i.e., reinforced insulation is not applied). Therefore, if a control signal cable or wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath or the cover might break down, which would expose the signal wire to a high voltage of the main circuit. Make sure that the control signal cables and wires will not come into contact with live conductors of the main circuit.

Failure to observe these precautions could cause electric shock and/or an accident.

Noise may be emitted from the inverter, motor and wires.

Take appropriate measure to prevent the nearby sensors and devices from malfunctioning due to such noise.

An accident could occur.

Table 2.10 lists the symbols, names and functions of the control circuit terminals. The wiring to the control circuit terminals differs depending upon the setting of the function codes, which reflects the use of the inverter. Route wires properly to reduce the influence of noise, referring to the notes on the following pages.

- Since low level analog signals are handled, these signals are especially susceptible to the external noise effects. Route the wiring as short as possible (within 66ft(20 m)) and use shielded wires. In principle, ground the shielded sheath of wires; if effects of external inductive noises are considerable, connection to terminal [11] may be effective. As shown in Figure 2.18, ground the single end of the shield to enhance the shielding effect.

- Use a twin contact relay for low level signals if the relay is used in the control circuit. Do not connect the relay's contact to terminal [11].

- When the inverter is connected to an external device outputting the analog signal, a malfunction may be caused by electric noise generated by the inverter. If this happens, according to the circumstances, connect a ferrite core (a toroidal core or an equivalent) to the device outputting the analog signal and/or connect a capacitor having the good cut-off characteristics for high frequency between control signal wires as shown in Figure 2.21.

- Do not apply a voltage of +7.5 VDC or higher to terminal [C1]. Doing so could damage the internal

2.3.8 Setting up slide switches and handling control circuit terminal symbol plate

Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and wait more than five minutes for models of 30HP for 208V, 40HP for 460V or below, or ten minutes for models of 40HP for 208V, 50HP for 460V or above. Make sure that the LED monitor and charging lamp (on models of 40HP for 208V, 50HP for 460V or above) are turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P (+) and N (-) has dropped below the safe voltage (+25 VDC).

An electric shock may result if this warning is not heeded as there may be some residual electric charge in the DC bus capacitor even after the power has been turned off.

 Setting up the slide switches

Switching the slide switches located on the control PCB allows you to customize the operation mode of the analog output terminals, digital I/O terminals, and communications ports. The locations of those switches are shown in Figure 2.29.

To access the slide switches, remove the front and terminal block covers so that you can watch the control PCB. For models of 40HP for 208V, 50HP for 460V or above, open also the keypad enclosure.

For a screw terminal base, close the control circuit terminal symbol plate since the plate being opened interferes with switching of some switches.

 For details on how to remove the front cover, terminal block cover, and keypad enclosure, refer to Section

2.3.1, "Removing and mounting the terminal block (TB) cover and the front cover" and Chapter 1, Section

1.2, "External View and Terminal Blocks," Figure 1.4.

2.5 Cautions Relating to Harmonic Component, Noise, and Leakage Current

(1) Harmonic component

Input current to an inverter includes a harmonic component, which may affect other loads and power factor correcting capacitors that are connected to the same power source as the inverter. If the harmonic component causes any problems, connect a DC reactor (option) to the inverter. It may also be necessary to connect an AC reactor to the power factor correcting capacitors.

(2) Noise

If noise generated from the inverter affects other devices, or that generated from peripheral equipment causes the inverter to malfunction, follow the basic measures outlined below.

1) If noise generated from the inverter affects the other devices through power wires or grounding wires:

- Isolate the grounded metal frames of the inverter from those of the other devices.

- Connect a noise filter to the inverter power wires.

- Isolate the power system of the other devises from that of the inverter with an insulated transformer.

2) If induction or radio noise generated from the inverter affects other devices through power wires or grounding wires:

- Isolate the main circuit wires from the control circuit wires and other device wires.

- Put the main circuit wires through a metal conduit and connect the pipe to the ground near the inverter.

- Install the inverter onto the metal switchboard and connect the whole board to the ground.

- Connect a noise filter to the inverter power wires.

3) When implementing measures against noise generated from peripheral equipment:

- For the control signal wires, use twisted or shielded-twisted wires. When using shielded-twisted wires, connect the shield of the shielded wires to the common terminals of the control circuit or ground.

- Connect a surge absorber in parallel with a coil or solenoid of the magnetic contactor.

(3) Leakage current

Harmonic component current generated by insulated gate bipolar transistors (IGBTs) switching on/off inside the inverter becomes leakage current through stray capacitors of inverter input and output wires or a motor. If any of the problems listed below occur, take an appropriate measure against them.

Table 2.12 Leakage Current Countermeasures

Problem Measures

An earth leakage circuit breaker* (a ground fault circuit interrupter) that is connected to the input (primary) has tripped.

* With overcurrent protection

An external thermal relay was activated.

1) Decrease the carrier frequency.

2) Make the wires between the inverter and motor shorter.

3) Use an earth leakage circuit breaker (a ground fault circuit interrupter) that has a longer sensitive current than one currently being used.

4) Use an earth leakage circuit breaker (a ground fault circuit interrupter) that features measures against harmonic component (Fuji SG and EG series).

1) Decrease the carrier frequency.

2) Increase the settling current of the thermal relay.

3) Use the electronic thermal relay built in the inverter, instead of an external thermal relay.

 Switching the operation mode between remote and local

The inverter can be operated either in remote mode or in local mode. In remote mode, which applies to normal operation, the inverter is driven under the control of the data settings held in it, whereas in local mode, which applies to maintenance operation, it is separated from the system and is driven manually under the control of the keypad.

Remote mode: The sources for setting run and frequency commands is determined by various

setting means switching signals such as function codes, switching of run command 1/2, and link priority function.

Local mode: The sources for setting run and frequency commands is the keypad, regardless of the

settings specified by function codes. The keypad takes precedence over the setting means specified by the run command 1/2 or the link priority function.

What follows shows the setting means of run command using the keypad in the local operation mode.

key on the keypad.

The source for setting run and frequency commands can be switched between Remote and Local modes by the

key on the keypad. (This key is a toggle switch: Each time you press it for more than 1 second, the mode

switches from Romote to Local or vice versa.)

The mode can be switched also by an external digital input signal. To enable the switching you need to assign (LOC) to one of the digital input terminals, which means that the commands from the keypad are given precedence (one of function codes E01 to E05, E98, or E99 must be set to "35"). By factory default, (LOC) is assigned to [X5]. You can confirm the current mode on the indicators (REM: Remote mode; LOC: Local mode).

When the mode is switched from Remote to Local, the frequency settings in the Remote mode are automatically inherited. Further, if the inverter is in Running mode at the time of the switching from Remote to Local, the Run command is automatically turned ON so that all the necessary data settings will be carried over. If, however, there is a discrepancy between the settings on the keypad and those on the inverter itself (e.g., switching from reverse rotation in the Remote mode to forward rotation in the Local mode using the keypad that is for forward rotation only), the inverter automatically stops.

The paths of transition between Remote and Local modes depend on the current mode and the value (ON/OFF) of (LOC), the signal giving precedence to the commands from the keypad, as shown in the state transition diagram (Figure 3.5) given below.

 For further details on how to set operation commands and frequencies in Remote and Local modes, refer

to the FRENIC-Eco User’s Manual, Chapter 4 "BLOCK DIAGRAMS FOR CONTROL LOGIC" (especially Section 4.3 “Drive Command Generator” block diagram).

3.3.2 Setting up the frequency and PID process commands

You can set up the desired frequency command and PID process command by using

and keys on the

keypad.

You can also view and set up the frequency command as load shaft speed by setting function code E48.

 Setting the frequency command

• The frequency setting can be saved either automatically as mentioned above or by pressing the key. You can choose either way using function code E64.

• When you start specifying or changing the frequency command or any other parameter with the

/ key, the lowest digit on the display will blink and start changing. As you are holding the key down, blinking will gradually move to the upper digit places and the upper digits will be changeable.

• Pressing the

key moves the changeable digit place (blinking) and thus allows you to change

upper digits easily.

• By setting function code C30 to "0: Keypad operation (

 Hexadecimal expression

Each I/O terminal is assigned to one of the 16 binary bits (bit 0 through bit 15). The bit to which no I/O terminal is assigned is considered to have a value of "0." The I/O signals are thus collectively expressed as a hexadecimal number (0 through F).

In the FRENIC-Eco Series, digital input terminals [FWD] and [[REV] are assigned to bits 0 and 1, and [X1] through [X5] to bits 2 through 6, respectively. Each bit assumes a value of "1" when the corresponding signal is ON and a value of "0" when it is OFF

(Note)

. For example, when signals [FWD] and [X1] are ON while all the

other signals are OFF, the status is expressed as "0005H."

(Note) The ON/OFF state of each signal at terminals [FWD], [REV], and X1 through [X5] is to be interpreted according to

the states of the source/sink switch as shown in Table 2.8 in Chapter 2 of the FRENIC-Eco Instruction Manual.

Digital output terminals [Y1] through [Y3] are assigned to bits 0 through 2. Each is given a value of "1" when it is short-circuited to [CMY], or a value of "0" when its circuit to [CMY] is open. The status of relay output terminal [Y5A/C] is assigned to bit 4, which assumes a value of "1" when the contact between [Y5A] and [Y5C] is closed. The status of relay output terminal [30A/B/C] is assigned to bit 8, which assumes a value of "1" when the contact between [30A] and [30C] is closed or "0" when the contact between [30B] and [30C] is closed. For example, when terminal [Y1] is ON, terminals [Y2] and [Y3]] are OFF, the contact between [Y5A] and [Y5C] is opened, and the link between 30A and 30C is closed, the status is expressed as "0101H."

Updating of the function code data in the inverter is incomplete, with some of it remaining old. Do not run the inverter in this state. Before running the inverter, redo the writing or perform initialization.

For safety considerations, the following situations are treated as an error:

• No valid data is found in the keypad’s memory. (No Read

operation has been performed since factory shipment; or, a Read operation has been cancelled or aborted.)

• The data held in the keypad’s memory has an error.

• There is a mismatch in inverter’s model number.

• A Write operation has been performed while the inverter is

running.

• The inverter is data-protected.

• The Write enable for keypad command (WE-KP) is OFF.

The function code data held in the keypad is incompatible with that in the inverter. (Either data may be non-standard; or a version upgrade performed in the past may have made the keypad or the inverter incompatible. Contact your Fuji Electric representative.)
