Japanese Guideline for Suppressing Harmonics in Home Electric and Gen- eral-purpose Appliances

Fuji three-phase 200 V class series of inverters with a capacity of 3.7 (4.0) kW or less, single-phase 200 V class series with 2.2 kW or less, and single-phase 100 V class series with 0.75 kW or less were once subject to the "Japanese Guideline for Suppressing Harmonics in Home Electric and General-purpose Appliances" (established in September 1994 and revised in October 1999), published by the Ministry of International Trade and Industry (currently the Ministry of Economy, Trade and Industry (METI)).

Since the revision of the guideline in January 2004, however, these inverters have no longer been subject to the guideline. The individual inverter manufacturers have voluntarily employed harmonics suppression measures.

As our measure, it is recommended that DC reactors (DCRs) authorized in this manual be connected to the FRENIC-Mini series of inverters.

When using DCRs not authorized in this manual, however, consult your Fuji Electric representative for the detailed specifications.

Japanese Guideline for Suppressing Harmonics by Customers Receiving High Voltage or Special High Voltage

Refer to the FRENIC-Mini User's Manual (24A7-E-0023), Appendix C for details on this guideline.

Safety precautions

Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or maintenance and inspection. Ensure you have sound knowledge of the device and familiarize yourself with all safety information and precautions before proceeding to operate the inverter.

Safety precautions are classified into the following two categories in this manual.

Failure to heed the information indicated by this symbol may lead to dangerous conditions, possibly resulting in death or serious bodily injuries.

Failure to heed the information indicated by this symbol may lead to dangerous conditions, possibly resulting in minor or light bodily injuries and/or substantial property damage.

Failure to heed the information contained under the CAUTION title can also result in serious consequences. These safety precautions are of utmost importance and must be observed at all times.

Application

•FRENIC-Mini is designed to drive a three-phase induction motor and three-phase permanent magnet synchronous motor (PMSM). Do not use it for single-phase motors or for other purposes.

Fire or an accident could occur.

•FRENIC-Mini may not be used for a life-support system or other purposes directly related to the human safety.

•Though FRENIC-Mini 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.

iv

•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)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of power lines. Use the devices within the recommended current range.

•Use wires in the specified size.

•When wiring the inverter to the power supply of 500 kVA or more, be sure to connect an optional DC reactor (DCR).

Otherwise, fire could occur.

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

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

Doing so could cause fire.

•Be sure to connect the grounding wires without fail.

Otherwise, electric shock or fire could occur.

•Qualified electricians should carry out wiring.

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

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

Otherwise, electric shock could occur.

•Be sure to perform wiring after installing the inverter body.

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.

Otherwise fire or an accident could occur.

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

•Do not insert a braking resistor between terminals P (+) and N (-), P1 and N (-), P (+) and P1, DB and N (-), or P1 and DB.

Doing so could cause fire or an accident.

v

•Generally, control signal wires are not reinforced insulation. If they accidentally touch any of live parts in the main circuit, their insulation coat may break for any reasons. In such a case, an extremely high voltage may be applied to the signal lines. Make a complete remedy to protect the signal line from contacting any hot high voltage lines.

Doing so could cause an accident or electric shock.

•Wire the three-phase motor to terminals U, V, and W of the inverter, aligning phases each other.

Otherwise injuries could occur.

•The inverter, motor and wiring generate electric noise. Take care of malfunction of the nearby sensors and devices. To prevent the motor from malfunctioning, implement noise control measures.

Otherwise an accident could occur.

Operation

•Be sure to install the terminal block cover before turning the power on. Do not remove the cover while power is applied.

Otherwise electric shock could occur.

•Do not operate switches with wet hands.

Doing so could cause electric shock.

•If the retry function has been selected, the inverter may automatically restart and drive the motor depending on the cause of tripping.

(Design the machinery or equipment so that human safety is ensured after restarting.)

•If the stall prevention function (current limiter), automatic deceleration, and overload prevention control have been selected, the inverter may operate at an acceleration/deceleration time or frequency different from the set ones. Design the machine so that safety is ensured even in such cases.

Otherwise an accident could occur.

•The STOP key is only effective when function setting (Function code F02) has been established to enable the STOP key. Prepare an emergency stop switch separately. If you disable the STOP key priority function and enable operation by external commands, you cannot emergency-stop the inverter using the STOP key on the built-in keypad.

•If an alarm reset is made with the operation signal turned on, a sudden start will occur. Ensure that the operation signal is turned off in advance.

Otherwise an accident could occur.

vi

•If you enable the "restart mode after momentary power failure" (Function code F14 = 4 or 5), then the inverter automatically restarts running the motor when the power is recovered. (Design the machinery or equipment so that human safety is ensured after restarting.)

•If you set the function codes wrongly or without completely understanding this instruction manual and the FRENIC-Mini User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.

An accident or injuries could occur.

•Do not touch the inverter terminals while the power is applied to the inverter even if the inverter stops.

Doing so could cause electric shock.

•Do not turn the main circuit power on or off in order to start or stop inverter operation.

Doing so could cause failure.

•Do not touch the heat sink or braking resistor because they become very hot.

Doing so could cause burns.

•Setting the inverter to high speeds is easy. Before changing the frequency (speed) setting, check the specifications of the motor and machinery.

•The brake function of the inverter does not provide mechanical holding means.

Injuries could occur.

Maintenance and inspection, and parts replacement

•Turn the power off and wait for at least five minutes before starting inspection. Further, check that the LED monitor is unlit, and check the DC link bus voltage between the P (+) and N (-) terminals to be lower than 25 VDC.

Otherwise, electric shock could occur.

•Maintenance, inspection, and parts replacement should be made only by qualified persons.

•Take off the watch, rings and other metallic matter before starting work.

•Use insulated tools.

Otherwise, electric shock or injuries could occur.

vii

Disposal

•Handle the inverter as an industrial waste when disposing of it.

Otherwise injuries could occur.

Others

•Never attempt to modify the inverter.

Doing so could cause electric shock or injuries.

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 to the Low Voltage Directive in the EU

If installed according to the guidelines given below, inverters marked with CE are considered as compliant with the Low Voltage Directive 2006/95/EC.

1.The ground terminal G should always be connected to the ground. Do not use only a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)* as the sole method of electric shock protection. Be sure to use ground wires whose size is greater than power supply lines.

*With overcurrent protection.

2.When used with the inverter, a molded case circuit breaker (MCCB), resid- ual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) or magnetic contactor (MC) should conform to the EN or IEC standards.

3.When you use a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) for protection from electric shock in direct or indirect contact power lines or nodes, be sure to install type B of RCD/ELCB on the input (primary) of the inverter if the power source is three-phase 200/400 V. For single-phase 200 V power supplies, use type A.

When you use no RCD/ELCB, take any other protective measure that isolates the electric equipment from other equipment on the same power supply line using double or reinforced insulation or that isolates the power supply lines connected to the electric equipment using an isolation transformer.

4.The inverter should be used in an environment that does not exceed Pollution Degree 2 requirements. If the environment conforms to Pollution Degree 3 or 4, install the inverter in an enclosure of IP54 or higher.

5.Install the inverter, AC or DC reactor, input or output filter in an enclosure with minimum degree of protection of IP2X (Top surface of enclosure shall be minimum IP4X when it can be easily accessed), to prevent human body from touching directly to live parts of these equipment.

6.To make an inverter with no integrated EMC filter conform to the EMC directive, it is necessary to connect an external EMC filter to the inverter and install them properly so that the entire equipment including the inverter conforms to the EMC directive.

7.Do not connect any copper wire directly to grounding terminals. Use crimp terminals with tin or equivalent plating to connect them.

8.To connect the three-phase or single-phase 200 V class series of inverters to the power supply in Overvoltage Category III or to connect the three-phase 400 V class series of inverters to the power supply in Overvoltage Category II or III, a supplementary insulation is required for the control circuitry.

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

10.The power supply mains neutral has to be earthed for the three-phase 400 V class inverter.

11.The inverter has been tested with IEC61800-5-1 2007 5.2.3.6.3 Short-circuit Current Test under the following conditions.

Short-circuit current in the supply: 10 kA

Maximum 240 V Maximum 480 V

Precautions for use

			When driving a 400 V general-purpose motor with an inverter
		Driving a 400 V	using extremely long wires, damage to the insulation of the
			motor may occur. Use an output circuit filter (OFL) if neces-
		general-purpose
			sary after checking with the motor manufacturer. Fuji motors
		motor
			do not require the use of output circuit filters because of their
			good insulation.
			When the inverter is used to run a general-purpose motor, the
		Torque charac-	temperature of the motor becomes higher than when it is
			operated using a commercial power supply. In the low-speed
		teristics and	range, the cooling effect will be weakened, so decrease the
		temperature rise	output torque of the motor. If constant torque is required in
			the low-speed range, use a Fuji inverter motor or a motor

		Vibration	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
		Noise	motor noise level is higher than that with a commercial power
			supply. To reduce noise, raise carrier frequency of the in-
			verter. Operation at 60 Hz or higher can also result in higher
			noise level.
		High-speed mo-	If the reference frequency is set to 120 Hz or more to drive a
			high-speed motor, test-run the combination of the inverter
		tors
			and motor beforehand to check for safe operation.
		Explosion-proof	When driving an explosion-proof motor with an inverter, use a
			combination of a motor and an inverter that has been ap-
		motors
			proved in advance.
			These motors have a larger rated current than gen-
	In running	Submersible mo-	eral-purpose motors. Select an inverter whose rated output

	special mo-
		tors and pumps	These motors differ from general-purpose motors in thermal

			(secondary) circuit by mistake, the brake will not work.
			Do not use inverters for driving motors equipped with se-
			ries-connected brakes.

			Chapter 7, Section 7.5 "Insulation Test."
		Control circuit	When using remote control, limit the wiring length between
			the inverter and operator box to 20 m or less and use twisted
		wiring length
			pair or shielded cable.
			If long wiring is used between the inverter and the motor, the
		Wiring length	inverter will overheat or trip as a result of overcurrent
			(high-frequency current flowing into the stray capacitance) in
		between inverter
			the wires connected to the phases. Ensure that the wiring is
		and motor
	Wiring		shorter than 50 m. If this length must be exceeded, lower the
			carrier frequency or mount an output circuit filter (OFL).
		Wiring size	Select wires with a sufficient capacity by referring to the
			current value or recommended wire size.
		Wiring type	Do not use one multicore cable in order to connect several
			inverters with motors.
		Grounding	Securely ground the inverter using the grounding terminal.
			Select an inverter according to the nominal applied motor
		Driving gen-	listed in the standard specifications table for the inverter.
	Selecting	eral-purpose	When high starting torque is required or quick acceleration or
	inverter	motor	deceleration is required, select an inverter with a capacity

1.4 Storage Environment

1.4.1Temporary 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	-25 to +70°C		Locations where the inverter is not
temperature *1			subject to abrupt changes in
Relative	5 to 95% *2		temperature that would result in the
humidity			formation of condensation or ice.
Atmosphere	The inverter must not be exposed to dust, direct sunlight, corrosive or flammable
	gases, oil mist, vapor, water drops or vibration. The atmosphere can contain only a
	low level of salt. (0.01 mg/cm2 or less per year)
Atmospheric	86 to 106 kPa (in storage)
pressure
	70 to 106 kPa (during transportation)

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

*2 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.

Precautions for temporary storage

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

(2)If the environment does not satisfy the specified requirements listed in Table 1.1, 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).

1.4.2Long-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. 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.

1-3

Chapter 2 MOUNTING AND WIRING OF THE INVERTER

2.1 Operating Environment

Install the inverter in an environment that satisfies the requirements listed in Table 2.1.

Table 2.2 Output Current Derating Factor in

Relation to Altitude

	Altitude	Output current
		derating factor
	1000 m or lower	1.00
	1000 to 1500 m	0.97
	1500 to 2000 m	0.95
	2000 to 2500 m	0.91
	2500 to 3000 m	0.88

(Note 1) When inverters are mounted side-by-side without any gap between them, the ambient temperature should be within the range from -10 to +40°C.

(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 panel of your system or other dustproof containers.

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

2.2 Installing the Inverter

(1) Mounting base

The temperature of the heat sink may 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.

Install the inverter on a base made of 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 panel of your system, take extra care with ventilation inside the panel as the temperature around the inverter tends to increase.

2-1

Top 100 mm

Left	Right
10 mm	10 mm

Bottom 100 mm

Figure 2.1 Mounting Direction and

Required Clearances

When mounting two or more inverters

When mounting two or more inverters in the same unit or panel, basically lay them out side by side. As long as the ambient temperature is 40°C or lower, inverters can be mounted side by side without any clearance between them. When mounting the inverters necessarily, one above the other, be sure to separate them with a partition plate or the like so that any heat radiating from an inverter will not affect the one(s) above.

(3) Mounting direction

Secure the inverter to the mounting base with four screws or bolts (M4) so that the FRENIC-Mini logo faces outwards. Tighten those screws or bolts perpendicular to the mounting base.

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 not run.

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.

2.3 Wiring

Follow the procedure below. (In the following description, the inverter has already been installed.)

2.3.1Removing and mounting the terminal block covers

(1)Loosen the screw securing the control circuit terminal block cover.

(2)Insert your finger in the cutout (near "PULL") in the bottom of the control circuit terminal block cover, then pull the cover towards you.

(3)Hold both sides of the main circuit terminal block cover between thumb and forefinger and slide it towards you.

(4)After performing wiring, mount the main circuit terminal block cover and control circuit terminal block cover in the reverse order of removal.

2-5

2.3.4Wiring 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 power wires to the main circuit power input terminals L1/R, L2/S and L3/T (for three-phase voltage input) or L1/L and L2/N (for single-phase voltage input) 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 residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of power lines. Use the devices within the related 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 killer to the inverter's output (secondary) circuit.

Doing so could cause fire.

•Be sure to connect the grounding wires without fail.

Otherwise, electric shock or fire could occur.

•Qualified electricians should carry out wiring.

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

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

Otherwise, electric shock could occur.

•Be sure to perform wiring after installing the inverter body.

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.

Otherwise, fire or an accident could occur.

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

•Do not connect a braking resistor to between terminals P (+) and N (-), P1 and N (-), P (+) and P1, DB and N (-), or P1 and DB.

Doing so could cause fire or an accident.

*1 Use either one of these two grounding terminals on the main circuit terminal block. *2 Perform wiring as necessary.

CAUTION: The above is an illustration. Do not connect more than 2 wires to terminal P (+).

CAUTION: When wiring the inverter to the power supply of 500 kVA or more, be sure to connect an optional DC reactor (DCR).

Figure 2.3 Wiring Procedure for Peripheral Equipment

2-7

The wiring procedure for the FRN0006C2S-2 is given below as an example. For other inverter types, perform wiring in accordance with their individual terminal arrangement. (Refer to page 2-3.)

c Grounding terminal (G)

Be sure to ground either of the two grounding terminals for safety and noise reduction. It is stipulated by the Electric Facility Technical Standard that all metal frames of electrical equipment must be grounded 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)Connect a thick grounding wire with a large surface area. Keep the wiring length as short as possible.

d Inverter output terminals, U, V, W and grounding terminal (G)

1)Connect the three wires of the three-phase motor to terminals U, V, and W, aligning phases each other.

2)Connect the grounding wire of terminals U, V, and W to the grounding terminal (G).

-The wiring length between the inverter and motor should not exceed 50 m. If it exceeds 50 m, it is recommended that an output circuit filter (option) be inserted.

-Do not use one multicore cable to connect several inverters with motors.

•Do not connect a phase-advancing capacitor or surge absorber to the inverter’s output lines (secondary circuit).

•If the wiring length is long, the stray capacitance between the wires will increase, resulting in an outflow of the leakage current. It will activate the overcurrent protection, increase the leakage current, or will not assure the accuracy of the current display. In the worst case, the inverter could be damaged.

•If more than one motor is to be connected to a single inverter, the wiring length should be the total length of the wires to the motors.

2-8

Driving 400 V series motor

•If a thermal relay is installed in the path between the inverter and the motor to protect the motor from overheating, the thermal relay may malfunction even with a wiring length shorter than 50 m. In this situation, add an output circuit filter (option) or lower the carrier frequency (Function code F26: Motor sound (Carrier frequency)).

•If the motor is driven by a PWM-type inverter, surge voltage that is generated by switching the inverter component may be superimposed on the output voltage and may be applied to the motor terminals. Particularly if the wiring length is long, the surge voltage may deteriorate the insulation resistance of the motor. Consider any of the following measures.

-Use a motor with insulation that withstands the surge voltage. (All Fuji standard motors feature insulation that withstands the surge voltage.)

-Connect an output circuit filter (option) to the output terminals (secondary circuits) of the inverter.

-Minimize the wiring length between the inverter and motor (10 to 20 m or less).

e 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 10 m or below.

•If both a DC reactor and a braking resistor are to be connected to the inverter, secure

both wires of the DC reactor and braking resistor together to terminal P(+). (Refer to item f on the next page.)

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

When wiring the inverter to the power supply of 500 kVA or more, be sure to connect an optional DC reactor (DCR).

Otherwise, fire could occur.

Figure 2.4 Location of Jumper Bar

2-9

f Braking resistor terminals, P(+) and DB

1)Connect terminals P and DB of a braking resistor (option) to terminals P(+) and DB on the main circuit terminal block.

2)Arrange the inverter and braking resistor to keep the wiring length to 5 m or less and twist the two wires or route them together in parallel.

Do not connect a braking resistor to any inverter of FRN0002C2S-2 /-7 or below. (Even if connected, the braking resistor will not work.)

Never insert a braking resistor between terminals P(+) and N(-), P1 and N(-), P(+) and P1, DB and N(-), or P1 and DB.

Doing so could cause fire.

When a DC reactor is not to be connected together with the braking resistor

1)Remove the screws from terminals P(+) and P1, together with the jumper bar.

2)Connect the wire from terminal P of the braking resistor to terminal P(+) of the inverter and put the jumper bar back into place. Then secure the wire and jumper bar with the screw.

3)Tighten the screw of terminal P1 on the jumper bar.

4)Connect the wire from terminal DB of the braking resistor to the DB of the inverter.

When connecting a DC reactor together with the braking resistor

1)Remove the screw from terminal P(+).

2)Overlap the DC reactor wire and braking resistor wire (P) and then secure them to terminal P(+) of the inverter with the screw.

3)Connect the wire from terminal DB of the braking resistor to terminal DB of the inverter.

4)Do not use the jumper bar.

g 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.
