Application
•FRENIC-Multi is designed to drive a three-phase induction motor. Do not use it for single-phase motors or for other purposes.
Fire or an accident could occur.
•FRENIC-Multi may not be used for a life-support system or other purposes directly related to the human safety.
•Though FRENIC-Multi 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.
i
Installation
•Install the inverter on a nonflammable material such as metal.
Otherwise fire could occur.
•Do not place flammable object 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 supply, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/a ground fault circuit interrupter (GFCI)(with overcurrent protection). Use the devices within the recommended current range.
•Use wires in the specified size.
•When wiring the inverter to the power supply that is 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.
•Ground the inverter in compliance with the national or local electric code.
Otherwise, electric shock 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 body.
Otherwise, electric shock or injuries could occur.
ii
•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 supply 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.
•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 cover before turning the power ON. Do not remove the covers while power is applied.
Otherwise electric shock could occur.
•Do not operate switches with wet hands.
Doing so could cause electric shock.
•If the auto-reset 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 commanded ones. Design the machine so that safety is ensured even in such cases.
Otherwise an accident could occur.
iii
•The key on the keypad is effective only when the keypad operation is enabled with function code F02 (= 0, 2 or 3). When the keypad operation is disabled, prepare an emergency stop switch separately for safe operations.
Switching the run command source from keypad (local) to external equipment (remote) by
turning ON the "Enable communications link" command LE disables the key. To enable the key for an emergency stop, select the STOP key priority with function code H96 (= 1 or 3).
•If an alarm reset is made with the Run command signal turned ON, a sudden start will occur. Ensure that the Run command signal is turned OFF in advance.
Otherwise an accident could occur.
•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-Multi 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 (circuit breaker) ON or OFF in order to start or stop inverter operation.
Doing so could cause failure.
•Do not touch the heat sink and 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.
iv
Maintenance and inspection, parts replacement, and installation of an option card
•Turn the power OFF and wait for at least five minutes before starting inspection, parts replacement, and installation of an option card. Further, check that the LED monitor is unlit and that the DC link bus voltage between the P (+) and N (-) terminals is 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 objects before starting work.
•Use insulated tools.
Otherwise, electric shock or injuries could occur.
Disposal
•Treat 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.
v
Conformity to the Low Voltage Directive in the EU
If installed according to the guidelines given below, inverters marked with CE or TÜV 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)/a ground fault circuit interrupter (GFCI)* 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), residual- current-operated protective device (RCD)/a ground fault circuit interrupter (GFCI) or magnetic contactor (MC) should conform to the EN or IEC standards.
3.When you use a residual-current-operated protective device (RCD)/a ground fault circuit interrupter (GFCI) for protection from electric shock in direct or indirect contact power lines or nodes, be sure to install type B of RCD/GFCI on the input (primary) of the inverter if the power supply is three-phase 230/460 V. For single-phase 230 V power supply, use type A.
When you use no RCD/GFCI, 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 230 V class series of inverters to the power supply in Overvoltage Category III or to connect the three-phase 460 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 you use an inverter at an altitude of more than 6600ft (2000 m), you should apply basic insulation for the control circuits of the inverter. The inverter cannot be used at altitudes of more than 9800ft (3000 m).

Precautions for use
|
|
When driving a 460V general-purpose motor with an inverter |
|||||||
|
Driving a 460 V |
using extremely long wires, damage to the insulation of the |
|||||||
|
motor may |
occur. Use an output |
circuit |
filter (OFL) if |
|||||
|
general-purpose |
||||||||
|
necessary after checking with the motor manufacturer. Fuji |
||||||||
|
motor |
||||||||
|
motors do not require the use of output circuit filters because |
||||||||
|
|
||||||||
|
|
of their reinforced insulation. |
|
|
|
|
|
||
|
|
|
|||||||
|
Torque |
When the inverter is used to run a general-purpose motor, |
|||||||
|
the temperature of the motor becomes higher than when it is |
||||||||
|
characteristics |
||||||||
|
operated using a commercial power supply. In the low-speed |
||||||||
|
and temperature |
||||||||
|
range, the cooling effect will be weakened, so decrease the |
||||||||
|
rise |
||||||||
|
output torque of the motor. |

|
|
|
|
|

In running |
|
|
|
|
|
|
|
|
|
|
When an inverter-driven motor is mounted to a machine, |
||||||||
general- |
|
||||||||
|
resonance may be caused by the natural frequencies of the |
||||||||
purpose |
|
||||||||
|
machine system. |
|
|
|
|
|
|
||
motors |
|
|
|
|
|
|
|
||
|
Note that operation of a 2-pole motor at 60 Hz or higher may |
||||||||
|
|
||||||||
|
Vibration |
cause abnormal vibration. |
|
|
|
|
|
||
|
|
* The use of a rubber coupling or vibration-proof 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 |
||||||||
|
|
inverter. Operation at 60 Hz or higher can also result in higher |
|||||||
|
|
noise level. |
|
|
|
|
|
|
|
|
High-speed |
If the reference frequency is set to 120 Hz or more to drive a |
|||||||
|
high-speed motor, test-run the combination of the inverter |
||||||||
|
motors |
||||||||
|
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 |
|||||
|
motors |
||||||||
|
approved in advance. |
|
|

|
|
||
|
|
|
|
|
|
|
|
||
|
|
|
|
|
|
||||
|
|
These motors have a larger |
rated |
current |
than |
||||
|
Submersible |
general-purpose motors. Select an |
inverter |
whose |
rated |
||||
|
output current is greater than that of the motor. |
|
|
||||||
|
motors and |
|
|
||||||
|
These motors differ from general-purpose motors in thermal |

||||||||
motors |
|
||||||||
|
|
|
|
|
|
|
|
|
|
|
|
For motors equipped with parallel-connected brakes, their |
|||||||
|
|
power supply for brake must be supplied from the primary |
|||||||
|
Brake motors |
circuit. If the |
power |
supply for brake 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 |
|||||||
|
Geared motors |
gearbox or |
speed |
changer/reducer, |
then |
continuous |
|||
|
operation at low speed may cause poor lubrication. Avoid |

Control circuit |
When using remote control, limit the wiring length between |
|
|
the inverter and operator panel to 66ft (20 m) or less and use |
||
|
wiring length |
||
|
twisted pair or shielded wire. |
||
|
|
||
|
|
|
|
|
|
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 |
||
|
shorter than 164ft (50 m). If this length must be exceeded, |
||
Wiring |
|
||
|
lower the carrier frequency or mount an output circuit filter. |
||
|
|
|
|
|
Wiring size |
Select wires with a sufficient capacity by referring to the |
|
|
current value or recommended wire size. |
||
|
|
||
|
|
|
|
|
Wiring type |
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. |
|
|
|
|
|
|
|
Select an inverter according to the nominal applied motor |

rating listed in the standard specifications table for the |
|
|
inverter. |

|||
inverter |
deceleration is required, select an inverter with one rank |
||
|
|||

|
larger capacity than the standard. |
|
|
|
|
|
|
Driving special |
Select an inverter that meets the following condition: |
|
|

Inverter rated current > Motor rated current |
|
|
|
|
|
|
When exporting an inverter built in a panel or equipment, pack them in a previously |
||
|
fumigated wooden crate. Do not fumigate them after packing since some parts |
||
Transpor- |
inside the inverter may be corroded by halogen compounds such as methyl |
||
tation and |
bromide used in fumigation. |
||
storage |
When packing an inverter alone for export, use a laminated veneer lumber (LVL). |

1.3 Transportation
• When carrying an inverter, always support its bottom at the right and left sides with both hands. Do not hold covers or individual parts only.
• Avoid applying excessively strong force to the terminal block covers as they are made of plastic and are easily broken.
1.4 Storage Environment
1.4.1Temporary storage
Store the inverter in an environment that satisfies the requirements listed in Table 1.1.

*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, 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°C(14 F) to +30°C(86 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 within 70%.
(3)If the inverter has been installed in the equipment or control panel 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 inverter to a motor or run the motor.

(Note 1) When inverters are mounted side-by-side without any gap between them (less than 7.5HP), the ambient temperature should be within the range from –10 C(14 F) to +40 C(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 panel of your system or other dustproof containers.
(Note 3) If you use the inverter in an altitude above 3300ft(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 will rise up to approx. 90°C(194 F) 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 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 panel of your system, take extra care with ventilation inside the panel as the temperature around the inverter will tend to increase. Do not install the inverter in a small panel with poor ventilation.
Figure 2.1 Mounting Direction and
Required Clearances
2-1
When mounting two or more inverters
Horizontal layout is recommended when two or more inverters are to be installed in the same unit or panel. 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 less than 7.5 HP).
When employing external cooling
At the shipment time, the inverter is set up for mount inside your equipment or panel so that cooling is done all internally.
To improve cooling efficiently, you can take the heat sink out of the equipment or the panel (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 panel. As a result, much less heat is radiated inside the equipment or the panel.
To take advantage of external cooling, you need to use the external cooling attachment option for inverters with a capacity of 7.5 HP 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/E1" Installation Manual .
50°C
(122°F)"
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
(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-Multi" 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 not run.
(4) Solving abnormal vibration after installation
If any vibration in the surroundings reaches the inverter and causes abnormal vibration to the cooling fans or the keypad, fix them firmly using the fixing screws provided as accessories.
