1.1 Inspection Procedure upon Receiving
Before delivery, Every MA7200 PLUS inverter has been functionally tested and adjusted. After receiving the inverter,
use the following procedure to ensure that the proper equipment has been received and is not damaged.
Verify that the Model No. of the inverter you’ve received is the same as that listed on your purchase order.
(Refer to the Nameplate)
Observe the condition of the shipping container and report any damage immediately to the commercial carrier
that delivered the equipment.

MA7200 PLUS Operating Manual
TECO – Westinghouse Motor Company Wiring Precautions
3.3 Wiring Precautions
!
Do Not remove any protective covers or attempt any wiring while input power is
applied. Connect all wiring before applying input power. When making wiring changes
after power up, remove input power and wait a minimum of five minutes after power
has been turned off before starting. Also confirm that the charge lamp is off and that
DC voltage between terminals B1/P or (+) and (-) does not exceed 25V, otherwise
electric shock may result.
Only authorized personnel should work on the equipment. (Take off metal jewelry
such as watches and rings and use insulated tools.), otherwise electric shock or
injury may result.
(A) Power input terminals
1 - The Input power supply voltage can be connected in any phase sequence to power input terminals R/L1,
S/L2, or T/L3 on the terminal block.
2 - DO NOT connect the AC input 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. If it does not, swap any 2 of the output
cables to change motor direction.
5 - DO NOT connect phase correcting capacitors or LC/RC noise filter to the output circuit.
(B) Grounding
1 - Connect the ground terminal (E) to ground having a resistance of less than 100.
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 local codes and standards for 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 in Fig. 3.4.
Fig. 3.3.1 Inverter Grounding

MA7200 PLUS Operating Manual
TECO – Westinghouse Motor Company Power Input Wire Size & NFB and MCB Part Numbers
3.3.1 Input Power and Motor Cable Length
The length of the cables between the input power source and /or the motor and inverter can cause a significant
phase to phase voltage reduction due to the voltage drop across the cables. The wire size shown in Tables 3.4.1a
& b is based on a maximum voltage drop of 2%. If this value is exceeded, a wire size having larger diameter may be
needed. To calculate phase tot phase voltage drop, apply the following formula:
Phase-to-phase voltage drop (V) = 3 ×resistance of wire (Ω/km) × length of line m) × current×10-3.
(km=3280 x feet) (km=3.28 x feet )
3.3.2 Cable Length vs. Carrier Frequency
The allowable setting of the PWM carrier frequency is also determined by motor cable length and is specified in the
following Table 3.3.2.1.

inverter and motor

Recommended carrier
frequency allowed 15KHz max. 10KHz max. 5KHz max. 2.5KHz max.
Setting of parameter
Cn-34 6 4 2 1
3.3.3 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.
NOTES-
3.4 Power Input Wire Size, NFB and MCB Part Numbers
A non-fusible-breaker (NFB) should be installed between the AC source and the R/L1-S/L2-T/L3 input terminals of
MA7200 PLUS inverter. Depending on the application an optional electromagnetic contactor (MCB) may be installed.
To protect against nuisance trips, a ground fault detector should have sensitivity of >200mA and operation time>0.1
sec. The following Tables 3.4.1a (NEMA 1) and 3.4.1b (NEMA 4) show the ratings and part numbers for the various
horsepower.

TECO – Westinghouse Motor Company Control Terminals Functions
4.0 Control Terminals Designations and Wiring
There are three different control boards that are used with the MA7200 PLUS. Each one is used with a specific
horsepower range which is covered in the following explanations and in Fig. 2.1.1 and Fig. 2.1.2 in Section 2.
4.1 Control Terminals Layout
Fig. 4.1.1 MA7200 PLUS Control Board Terminal Layout
4.2 Control Circuit Wiring
(1) Separate the wiring for control circuit terminals RA-RB-RC (R1A-R2B-R2C) (Relay outputs) from wiring for
terminals - , A01, A02, GND, DO1, DO2, DOG 24V (or +12V, -12V), VIN, AIN, AUX, GND, IP12, IG12,
A (+), A (-), S (+) and S (-).
(2) Use shielded twisted-pair cables (#24 - #14 AWG / 0.5 -2 mm2) shown in Fig. 4.2.1 for control circuits to
minimize noise problems. The maximum wiring distance should not exceed 165 Ft. (50 m).
Fig. 4.2.1 Shielded Twisted-Pair
(3) When the digital multi-function output terminals (DO1, DO2) are connected to an external relay, a freewheeling
diode should be connected across the relay coil to prevent an inductive voltage spike from damaging the output
circuitry as shown in Fig. 4.2.2 below.
