Wiring Notes
Please read prior to Installation
During installation, follow all local electrical, construction, and
safety codes for the country in which the drive is installed.
Make sure that the appropriate protective devices (circuit breaker
or fuses) are connected between the power supply and AC drive.
Make sure that the leads are connected correctly and the AC drive
is properly grounded.
CAUTION!
Do not connect the AC power to the T1, T2, T3
terminals, it will damage the AC drive.
WARNING!
Make sure that all screws are tightened to the proper
torque rating shown in Table 3-2.
Use ground leads that comply with AWG/MCM standards and
keep them as short as possible.
Multiple MVX9000 units can be installed in one location. All the
units should be grounded directly to a common ground terminal.
The MVX9000 ground terminals may also be connected in parallel,
as shown in the figure below. Make sure there are no ground
loops.
Yes Yes No
When the AC drive output terminals U/T1, V/T2, and W/T3 are
connected to the motor terminals T1, T2, and T3, respectively, the
motor will rotate counterclockwise (as viewed from the shaft ends
of the motor) when a forward operation command is received. To
reverse the direction of motor rotation, switch over any of the two
motor leads.
Make sure that the power source is capable of supplying the
correct voltage and required current to the AC drive.
Forward
running
Do not attach or remove wiring when power is applied to the AC
drive.
Do not inspect components unless the inside “POWER” lamp has
turned off.

Chapter 3 – Storage and Installation
Do not monitor the signals on the circuit board while the AC drive
is in operation.
For the single-phase rated AC drives, the AC power can be
connected to any two of the three input terminals R/L1, S/L2, T/L3.
Note: This drive is not intended for the use with single-phase
motors.
Route the power and control wires separately, or at a 90 degree
angle to each other.
If a filter is required for reducing EMI (Electro Magnetic
Interference), install it as close as possible to the AC drive. EMI
can also be reduced by lowering the Carrier Frequency.
If the AC drive is installed in the place where a load reactor is
needed, install the filter close to U/T1, V/T2, W/T3 side of AC drive.
Do not use a Capacitor or L-C Filter (Inductance-Capacitance) or
R-C Filter (Resistance-Capacitance), unless approved by
Cutler-Hammer.
When using a GFCI (Ground Fault Circuit Interrupt), select a
current sensor with sensitivity of 200mA, and not less than
0.1-second detection to avoid nuisance tripping.
