System Setup Requirements
When using the ASD as an integral part of a larger system, it is the responsibility of the ASD
installer or maintenance personnel to ensure that there is a fail-safe in place, i.e., an arrangement
designed to switch the system to a safe condition if there is a fault or failure.
System safety features should be employed and designed into the integrated system in a manner
such that system operation, even in the event of system failure, will not cause harm or result in
personnel injury or system damage (i.e., E-Off, Auto-Restart settings, System Interlocks, etc.).
The programming setup and system configuration of the ASD may allow it to start the motor
unexpectedly. A familiarity with the Auto-restart settings is a requirement to use this product.
Improperly designed or improperly installed system interlocks may render the motor unable to
start or stop on command.
The failure of external or ancillary components may cause intermittent system operation, i.e.; the
system may start the motor without warning.
There may be thermal or physical properties, or ancillary devices integrated into the overall
system that may allow for the ASD to start the motor without warning. Signs at the equipment
installation must be posted to this effect.
If a secondary magnetic contactor (MC) is used between the ASD and the load, it should be
interlocked to halt the ASD before the secondary contact opens. If the output contactor is used for
bypass operation, it must be interlocked such that commercial power is never applied to the ASD
output terminals (U, V, and W).
Power factor improvement capacitors or surge absorbers must not be installed on the output of
the ASD.
Use of the built-in system protective features is highly recommended (i.e., E-Off, Overload
Protection, etc.).
The operating controls and system status indicators should be clearly readable and positioned
where the operator can see them without obstruction.
Additional warnings and notifications shall be posted at the equipment installation location as
deemed required by Qualified Personnel.

INTRODUCTION
Thank you for purchasing the T300MVi Medium Voltage ASD. This adjustable frequency, solid­state AC drive features a 3φ input isolation transformer with a 24-pulse converter design, a 32 -bit CPU, and a three-unit power module inverter section providing a 5 level output for 4160/3300V drives and 3 level output for 2400V drives. The T300MVi also features as standard, an 8 key Control Panel with a LCD screen and 2 discrete LED lamps to indicate Ready, Run, Local, Remote and Alarm/Fault.
On most power systems, this drive will meet IEEE-519-1992 harmonic regulation guidelines without installing additional harmonic filters. The input power factor is typically 0.95. The multi-level output produces a more sinusoidal voltage and reduces stress on the motor win ding insulation. This drive uses high capacity 3300V IGBTs to improve reliability, reduce switching losses, and improve control performance. The PP7 control processor and 6-layer control board achieves high integration a nd reliability.
- 1
INITIAL COMMISSIONING
The drive should be commissioned by qualified personnel only. Below are some general steps
required for commissioning.
CAUTION
Confirmation of Wiring
Make the following final checks before applying power to the unit:
1) Confirm that source power is connected to terminals L1, L2, L3 (R, S, T). Connection of
incoming source power to any other terminals will damage the drive. Other control voltages
may be required. Consult your custom equipment diagrams shipped with the drive for any
other requirements.
2) Verify that the power modules are properly installed and that there was no damage during
shipping or handling.
3) Verify that there are no loose connections or wires and that all of the required shipping split
connections have been made.
4) Verify all external control circuit wiring is complete and properly connected.
5) The 3-phase source power should be within the correct voltage and frequency tolerances.
6) The motor leads must be connected to terminals T1, T2, T3 (U, V, W).
7) Make sure there are no short circuits or inadvertent grounds and tighten any loose connector
terminal screws.
CAUTION
Start-Up and Test
Prior to releasing the drive system for regular operation after installation, the system must be adjusted and tested by qualified personnel. This assures correct operation of the equipment for
reasons of reliable and safe performance. It is important to make arrange ments for such a check and that time is allowed for it.
CAUTION
- 2
Cautions on Changing Setting Parameters
The setting data of the T300MVi MV is saved in an EEPROM, non-volatile memory. When the micro controller initializes at power-up, it reads the EEPROM data and copie s it to the RAM (Rando m Access Memory). From then on, the micro controller controls the drive using the values in the RAM.
When the setting parameters are changed, by the display-keypad or personal computer ("su pport tool"), only the execution parameters in RAM are changed. If they need to be stored, they must be manually written to the EEPROM. Without this operation, the next initialization or power up will cause them to be replaced by the old data.
When a write to the EEPROM is performed, write processing may take 30 seconds. Turning off the control power supply during write processing will make both the RAM and EEPROM data abnormal. When the power is turned on again, this abnormal data will result in an error ("CHECK ERROR") preventing the drive from running. If such an error occurs, the settings must be reloaded from a saved file. If no setting file exists, the drive must be re-commissioned.
CAUTION
Do not turn off the control power supply under any circumstances while writing data to the EEPROM.
- 3
INSPECTIONS AND MAINTENANCE
Maintenance and inspection is a particularly effective means to help prevent failures an d reduce down time. Creating equipment specific inspection and maintenance check sheets can help to perform maintenance and inspection effectively. Detailed inspections and regular maintenance should be carried out in short cycles initially until a schedule reflecting the site-specific conditions can be determined.
For items that are too high to reach, use a step ladder to gain access. Do not attempt to climb on the equipment.
CAUTION
DANGER
Daily Inspections
Daily inspections consist mainly of visual inspections on the following items. These observations should be made with all of the cubicle doors closed and safety covers installed. Any abnormalities discovered should immediately be repaired.
1) Check the temperature, the humidity, the presence of corrosive or explosive gases, and the
presence of dust in the area.
2) Check for any abnormal sound or vibration of the reactor, transformer, or cooling fans.
3) Check for abnormal odors such as the smell of burning insulating materials.
Regular Inspections
Carry out regular inspections with power off, locked out, and with confirmation that the bus voltage
is completely discharged. Use power lockout/tagout procedure on the disconnecting means in
accordance with applicable local electrical codes (in the U.S., see 2002 NEC Article 430-1 01) before performing any drive maintenance.
The first thing to do in maintenance and inspection is cleaning. Cleaning should be carried out according to the conditions of the equipment. Before starting cleaning, turn off the power supply and check that the main circuit voltage is reduced to 0. Clean dust with a vacuum, dry cloths. Note that excessive air pressure when blowing out equipment may damage parts and wiring. Do not use solvents to clean the drive. Substances stuck to the circuits, which cannot be removed by blowing, should be wiped away using a cloth. As a basic rule, cleaning should start from the upper parts and end at the lower parts. Cleaning of the lower parts last will allow proper removal of substances that could drop from the upper parts.

dust. To remove caked on dirt use water and a gentle detergent, rinse it with clean water and dry it.
Otherwise replace it with a new one. Cleaning with solvents is not recommended.
3) Main circuit parts and entire cubicle - Check to see if dust is stuck to the cubicl e interior or if there
is any discoloration, heat generation, abnormal sound, leakage, odor or damage with the reactor,
transformer, contactors, cables and connections, fuses, capacitors, lightening arrestor s, and
resistors. Check to see that no wires or mounted parts are broken, disconnected, loose or
damaged. High voltage standoffs, insulators, and cable can be cleaned with isopropyl alcohol.
4) Printed Wiring Boards - The boards, which are made up of ICs and electronic components, must
be protected from dust, corrosive gases and extreme temperatures. Pay attention to the installation
environment of the equipment. Regular inspections, the proper cleaning, and maintenance in an
optimal environment is essential for circuit boards. Since most of the components and parts are
small and vulnerable to external forces, when cleaning them, use a brush to carefully wipe off dust.
Inspect the boards for signs of component damage, heating, and corrosion.
Cautions on Handling Printed Wiring Boards
a) All maintenance work on the board should be carried out at least 15 minutes after all power supplies are turned off to allow the capacitors on the boards to discharge.
b) When removing the board, disconnect all the connectors and wires and remove the mounting screws from the upper part of the board first. At this time, be careful not to drop the boards or screws. When setting the board down, place it on a static free surface. Be careful not to damage any components.
c) When attaching the board, do so in the order opposite to the removing procedure. Be sure that all of the connectors and wires are connected correctly.
d) New boards are shipped in an anti-static bag. Use this bag to store them.
Note that the anti-static coating is only on the inner side of the bag.
5) Check the protection functions for proper operation (Door switches, OH, E-stop...)
6) Check the insulation resistance of the medium voltage circuits.

Recommended Spare Parts
Spare parts are an important part of downtime reduction. When parts in the drive have failed, on­hand spare parts are necessary to shorten the mean time to repair (MTTR). Since repla cement of discrete components is time consuming, it is recommended that entire assemblies be replaced. Recommended spare parts common to all drives are shown in the following tables. The recommende d spare rate and minimum amount can serve as references for the minimum number of spare parts relative to the total number of drives on site. It is recommended that the quantity be determined in accordance with the number drives on site. Many other parts are job specific. It is up to the end user to determine what other parts may be needed.
