SAFE OPERATION NOTES
Read this instruction manual thoroughly before installation, operation, maintenance
or inspection of the inverter. Only authorized personnel should be permitted to perform
maintenance, inspections or parts replacement.
In this manual, notes for safe operation are classified as:
“WARNING” or “CAUTION”.
WARNING : Indicates a potentially hazardous situation that, if not avoided,
could result in death or serious injury to personnel.
CAUTION : Indicates a potentially hazardous situation that, if not avoided,
may result in minor or moderate injury to personnel and damage
to the equipment.
“WARNING” and “CAUTION”
WARNING
yAlways turn off the input power supply before wiring terminals.
yAfter turning OFF the main circuit power supply, do not touch the circuit
components until the “CHARGE” LED is extinguished.
yNever connect power circuit output U/T1, V/T2, W/T3 to AC power supply.
CAUTION
yWhen mounting the MA7200 in a separate enclosure, install a fan or other cooling
device to keep the intake air temperature below 113oF (45oC).
yDo not perform a withstand voltage test to the inverter.
yAll the parameters of the inverter have been preset at the factory. Do not change
the settings unnecessarily.
This inverter has been placed through demanding tests at the factory before shipment.
After unpacking, check for the following:
1. Verify that part numbers on shipping carton and unit match the purchase order
sheet and/or packing list.
2. Do not install or operate any inverter that is damaged or missing parts.
3. Do not install or operate any inverter that has no QC marking.
Contact your local TECO authorized distributor or TECO representative if any of
the above irregularities have been found.

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)(resistancewire3drop(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

1-8
Example of connection between the MA7200 and typical peripheral devices are shown as below.
MCCB (Molded-Case Circuit Breaker)
yChoose the Molded Case Circuit Breaker (MCCB) o
f
proper current rating. Please refer to the selection guide
“1.10 Peripheral Units” on Page 1-22.
yDo not use a circuit breaker for start/stop operation.
yWhen 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)
yIt is not always necessary to have a Magnetic Contactor on
the input side. However, an input Magnetic Contactor can
be used to prevent an automatic restart after recovery from
an external power loss during remote control operation.
yDo not use the Magnetic Contactor for start/stop operation.
AC Reactor
yTo improve power factor or to reduce surge current, install
an AC Reactor on the input side of the MA7200.
Input Noise Filter
yWhen used with TECO specified Input Noise Filter, the
MA7200 will comply with EN55011 class A regulation.
yPlease refer to the selection guide “1.10 Peripheral Units”
on page 1-22.
MA7200 Inverter
yThe input power supply can be connected to any terminal
R/L1, S/L2, T/L3 on the terminal block.
yPlease connect the ground terminal E to the site ground
securely.
Output Noise Filter (Zero Phase Core)
yInstall an Output Noise Filter between the MA7200 and the
Induction Motor to eliminate noise transmitted between the
power line and the inverter.
yPlease refer to the selection guide “1.10 Peripheral
Devices” on page 1-22.
Induction Motor
yWhen 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.
yThe 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.

*3 : The control wire is the wire led to the pin terminals of control board.
*4 : In Table 3, the specified Part No. of NFB and MC are the item No. of the products of TECO. The
customer can use the same rating of similar products from other sources. To decrease the noise
interference, be sure to add R-C surge suppressor (R: 10Ω/5W, C: 0.1µF/1000VDC) at the 2
terminals of coils of electromagnetic contactor.

■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.

When the digital multi-function output terminals connect serially to an external relay, an
anti-parallel freewheeling diode should be applied at both ends of relay, as shown below.

(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.

(C) GROUNDING :
(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.

•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. > 329ft.
