1.4 Wiring between Inverter and Peripheral devices and notice

CAUTION

1. After turning OFF the main circuit power supply, do not touch the circuit

components or change any circuit components before the “CHARGE” lamps extinguished. (It indicates that there is still some charge in the capacitor).

2. Never do wiring work or take apart the connectors in the inverter while the power

is still on.

3. Never connect the inverter output U/T1, V/T2, W/T3 to the AC source.

4. Always connect the ground lead E to ground.

5. Never apply high voltage test directly to the components within the inverter. (The

semiconductor devices are vulnerable to high voltage shock.)

6. The CMOS IC on the control board is vulnerable to ESD. Do not try to touch the

control board.

7. If Sn-03 is 7,9,11 (2-wire mode) or is 8, 10, 12 (3-wire mode), except parameter

settings of Sn-01 and Sn-02, the other parameter settings will return to their initial settings at factory. If the inverter is initially operated in 3-wire mode (Sn-03= 8, 10, 12), the motor will rotate in CCW sense after setting changed to 2-wire mode. (Sn-03= 7, 9, 11). Be sure that the terminals 1 and 2 are OPEN so as not to harmful to personal or cause any potential damage to machines.

CAUTION

1. Determine the wire size for the main circuit so that the line voltage drop is within

2% of the rated voltage. If there is the possibility of excessive voltage drop due to wire length, use a larger wire (larger diameter) suitable to the required length

-3

10current(A)length(m) wire/km)(resistance wire3drop(V) voltageLine ×××Ω×=

2. If the length of the cable wire between the inverter and the motor exceeds 30m,

use a lower carrier frequency for PWM (adjust the parameter Cn-34). Refer to Page 3-21

1-7

Example of connection between the MA7200 and typical peripheral devices are shown as below.

 MCCB (Molded-Case Circuit Breaker)

Power supply

y Choose the Molded Case Circuit Breaker (MCCB) of

proper current rating. Please refer to the selection guide

Power supply switch(NFB) and earth leakage breaker

“1.10 Peripheral Units” on Page 1-22.

y Do not use a circuit breaker for start/stop operation. y When a ground fault interrupter is used, select the one with

no influence for high frequency. Setting current should be 200mA or above and the operating time at 0.1 second or longer to avoid false triggering.

 MC (Magnetic Contactor)

Electromagnetic contactor

y It is not always necessary to have a Magnetic Contactor on

the input side. However, an input Magnetic Contactor can

e used to prevent an automatic restart after recovery from

an external power loss during remote control operation.

y Do not use the Magnetic Contactor for start/stop operation.

 AC Reactor

AC reactor

y To improve power factor or to reduce surge current, install

an AC Reactor on the input side of the MA7200.

 Input Noise Filter

Input noise filter

y When used with TECO specified Input Noise Filter, the

MA7200 will comply with EN55011 class A regulation.

y Please refer to the selection guide “1.10 Peripheral Units”

on page 1-22.

 MA7200 Inverter

MA 7200 inverter

y The input power supply can be connected to any terminal

R/L1, S/L2, T/L3 on the terminal block.

y Please connect the ground terminal E to the site ground

securely.

 Output Noise Filter (Zero Phase Core)

Zero phase core

y Install an Output Noise Filter between the MA7200 and the

Induction Motor to eliminate noise transmitted between the power line and the inverter.

y Please refer to the selection guide “1.10 Peripheral

Devices” on page 1-22.

 Induction Motor

Induction motor

y When multiple motors are driven in parallel with an

inverter, the inverter rated current should be at least 1.1 times the total motor rated current.

y The inverter and the motor must be separately grounded.

1.7 Wiring main circuit and notice

■ Main circuit wiring

The non-fusible-breaker (NFB) should be installed between the AC source and the R/L1-S/L2-T/L3 input terminal of MA7200 inverter. The user can make his own decision of installing electromagnetic contactor block (MCB) or not. To protect against the false triggering of leakage-current, the user should install a leakage current breaker with amperage sensitivity≧200mA and operation time≧0.1 sec.

■ External circuit wiring precaution:

(A) Control circuit wiring:

(1) Separate the control circuit wiring from main circuit wiring (R/L1, S/L2, T/L3, U/T1,

V/T2, W/T3) and other high-power lines to avoid noise interruption.

(2) Separate the wiring for control circuit terminals RA-RB-RC (R1A-R2B-R2C) (contact

output) from wiring for terminals c～j, A01, A02, GND, DO1, DO2 , DOG 15V(or +12V, -12V), VIN, AIN, AUX, GND, IP12, IG12, A (+), A (-), S(+) and S(-).

(3) Use the twisted-pair or shielded twisted-pair cables for control circuits to prevent

operating faults. Process the cable ends as shown in Fig. 3. The max. wiring distance should not exceed 50 meter.

(B) Wiring the main circuit terminals:

(1) Input power supply can be connected to any terminal R/L1, S/L2 or T/L3 on the

terminal block. The phase sequence of input power supply is irrelevant to the phase sequence.

(2) Never connect the AC power source to the output terminals U/T1, V/T2 and. W/T3. (3) Connect the output terminals U/T1, V/T2, W/T3 to motor lead wires U/T1, V/T2, and

W/T3, respectively.

(4) Check that the motor rotates forward with the forward run source. Switch over any 2

of the output terminals to each other and reconnect if the motor rotates in reverse with the forward run source.

(5) Never connect a phase advancing capacitor or LC/RC noise filter to an output circuit.

1-15

(1) Always use the ground terminal (E) with a ground resistance of less than 100Ω. (2) Do not share the ground wire with other devices, such as welding machines or

power tools.

(3) Always use a ground wire that complies with the technical standards on electrical

equipment and minimize the length of ground wire.

(4) When using more than one inverter, be careful not to loop the ground wire, as

shown below.

(a) OK (b) OK (c) NO

Fig. 5. MA7200 ground winding

‧ Determine the wire size for the main circuit so that the line voltage drop is within

2% of the rated voltage. (If there is the possibility of excessive voltage drop, use a larger wire suitable to the required length)

‧ Installing an AC reactor

If the inverter is connected to a large-capacity power source (600kVA or more), install an optional AC reactor on the input side of the inverter. This also improves the power factor on the power supply side.

‧ If the cable between the inverter and the motor is long, the high-frequency

leakage current will increase, causing the inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency, as shown below:

Cable length < 100ft. 100-165ft. 166-328ft.

B. EMI SUPPRESSION ZERO PHASE CORE

)

‧ Model : JUNFOC046S －－－－－－－ ‧ Code No. : 4H000D0250001 ‧ According to the required power rating and wire size, select the matched ferrite core to

suppress EMI noise.

‧ The ferrite core can attenuate the frequency response at high frequency range (from

100KHz to 50MHz, as shown below). It should be able to attenuate the RFI from inverter to outside.

‧ The zero-sequence noise ferrite core can be installed either on the input side or on the

output side. The wire around the core for each phase should be winded by following the same convention and one direction. The more winding turns the better attenuation effect. (Without saturation). If the wire size is too big to be winded, all the wire can be grouped and go through these several cores together in one direction.
