Preface

Please read this manual thoroughly before use, and keep the manual at hand for later reference. Also make sure that this manual is delivered to the final users.

WARNING

ALWAYS READ THIS MANUAL THOROUGHLY BEFORE USING THE VAT2000

THIS INVERTER CONTAINS HIGH VOLTAGE CIRCUITS THAT MAY BE FATAL TO HUMANS. USE EXTREME CAUTION DURING INSTALLATION. MAINTENANCE MUST BE PERFORMED BY QUALIFIED TECHNICIANS, AND ALL POWER SOURCES MUST BE DISCONNECTED BEFORE ANY MAINTENANCE. SUFFICIENT NOTICE MUST BE GIVEN TO THE GENERAL OPERATORS AND WORKERS BEFORE STARTING.

∙ELECTRIC SHOCK MAY OCCUR IF THE FOLLOWING POINTS ARE NOT OBSERVED.

∙DO NOT OPEN THE OUTER-COVER (FRONT COVER) WHILE THE POWER IS ON.

∙A CHARGE STILL REMAINS IN THE INVERTER WHILE THE INDICATOR IS LIT EVEN IF THE POWER HAS BEEN TURNED OFF. DO NOT OPEN THE OUTERCOVER (FRONT COVER) IN THIS CASE. WAIT AT LEAST 10 MINUTES AFTER THE INDICATOR GOES OUT.

∙DO NOT CONTACT THE ELECTRICAL CIRCUIT WHILE THE CHARGE LAMP ON THE PCB IS LIT. PERFORM SERVICING, ETC., AFTER WAITING AT LEAST 10 MINUTES AFTER THE LAMP GOES OUT.

∙ALWAYS GROUND THE INVERTER CASE. THE GROUNDING METHOD MUST COMPLY WITH THE LAWS OF THE COUNTRY WHERE THE INVERTER IS BEING INSTALLED.

∙THE INVERTER MAY BE DESTROYED IF THE FOLLOWING POINTS ARE NOT OBSERVED.

∙OBSERVE THE INVERTER SPECIFICATIONS.

∙CONNECT ADEQUATE CABLES TO THE INPUT/OUTPUT TERMINALS.

∙ALWAYS KEEP THE INVERTER INTAKE/OUTTAKE PORTS CLEAN, AND PROVIDE ENOUGH VENTILATION.

∙ALWAYS OBSERVE THE CAUTIONS LISTED IN THIS INSTRUCTION MANUAL.

∙THERE MAY BE SOURCES OF NOISE AROUND THIS INVERTER AND MOTOR DRIVEN BY THIS INVERTER. CONSIDER THE POWER SUPPLY SYSTEM, INSTALLATION PLACE AND WIRING METHOD BEFORE INSTALLATION.

INSTALL THIS INVERTER AWAY FROM DEVICES THAT HANDLE MINUTE SIGNALS, SUCH AS MEDICAL EQUIPMENT IN PARTICULAR. ALSO SEPARATE THE DEVICES ELECTRICALLY, AND TAKE SUFFICIENT NOISE MEASURES.

∙TAKE SUFFICIENT SAFETY MEASURES WHEN USING THIS INVERTER FOR PASSENGER TRANSPORTATION, SUCH AS IN LIFTS (ELEVATORS).

2. Wiring

DANGER

∙Always turn the device’s input power OFF before starting wiring. Failure to do so could lead to electrical shocks or fires.

∙Carry out grounding that complies with the standards of the country where the inverter is being installed. Failure to do so could lead to electrical shocks or fires.

∙Wiring must always be done by a qualified electrician. Failure to observe this could lead to electrical shocks or fires.

∙Always install the device before starting wiring.

Failure to do so could lead to electrical shocks or injuries.

∙Prepare a breaker such as an MCCB that matches the capacity for the inverter’s power supply side Failure to do so could lead to fires.

CAUTION

∙Do not connect an AC power supply to the output terminals (U, V, W). Failure to observe this could lead to electrical shocks or fires.

∙Confirm that the product’s rated voltage and frequency match the power supply voltage and frequency. Failure to do so could lead to injuries or fires.

∙Install an overheating protection device on the dynamic electrical-discharge braking resistor, and shut off the power with an error signal.

Failure to do so could lead to fires in the event of abnormal overheating.

∙Do not directly connect a resistor to the DC terminals (between L+1, L+2, and L–). Failure to observe this could lead to fires.

∙Tighten the terminals screws with the designated tightening torque. Failure to do so could lead to fires.

∙Correct connect the output side (U, V, W).

Failure to do so could cause the motor to rotate in reverse and the machine to be damaged

.

3. Operation

DANGER

∙Always install the from cover before turning the input power ON. Never remove the cover while the power is ON. There are sections in the from PCB that are charged with high voltages.

Failure to observe this could lead to electrical shocks.

∙Never touch the switches with wet hands.

Failure to observe this could lead to electrical shocks.

∙Never touch the inverter’s terminals while the inverter power is ON even if the operation is stopped Failure to observe this could lead to electrical shocks

∙Selection of the retry function could lead to unexpected restarting when an alarm occurs. The machine may start suddenly if the power is turned ON when the automatic start function is selected Do not go near the machine.

Failure to do so could lead to injuries.

(Design the machine so that physical safety can be ensured even if the machine restarts.)

∙The machine may not stop when a stop command is issued if the deceleration stop function is selected. Prepare a separate emergency stop switch.

Failure to do so could lead to injuries.

∙Resetting of an alarm while the run signal is input could lead to unexpected restarting. Always confirm that the run signal is OFF before resetting the alarm.

Failure to do so could lead to injuries.

CAUTION

∙The heat sink and dynamic braking resistor are heated to high temperatures, so never touch them. Failure to observe this could lead to burns.

∙Do not block the inverter’s ventilation holes. Failure to observe this could lead to fires.

∙The inverter operation can easily be set from low speeds to high speeds, so confirm that the operation is within the tolerable range for the motor or machine before making settings.

Failure to do so could lead to injuries.

∙Prepare holding brakes when necessary. Holding is not possible with the inverter’s brake functions. Failure to do so could lead to injuries.

∙Confirm the operation of the motor as a single unit before operating the machine.

Failure to do so could lead to injuries or machine damage due to unforeseen movements.

∙Always prepare a safety backup device so that the machine is not placed in a hazardous situation when an error occurs in the inverter.

Failure to do so could lead to injuries or machine damage.

4. Maintenance, Inspection and Part Replacement

DANGER

∙Always wait at least 20 minutes after turning the input power OFF before starting inspections. Make sure that the displays on the operation panel have gone out before removing the front cover. Remove the front cover, and confirm that the «CHARGE» LED on the unit has gone out. Also check that the voltage between terminals L+1 or L+2 and L– is 15V or less before starting the inspections. (Check with the «CHARGE» LED if the unit is not provided with the L– terminal.)

Failure to observe this could lead to electrical shocks.

∙Maintenance, inspections and part replacement must be done by a designated person. (Remove all metal accessories such as watches, bracelets, etc., before starting the work.) (Always use an insulation measure tool.)

Failure to observe this could lead to electrical shocks and injuries.

∙Always turn the power OFF before inspecting the motor or machine . A potential is applied on the motor terminal even when the motor is stopped.

Failure to do so could lead to electrical shocks and injuries.

∙Do no use parts other than those designated for the replacement parts. Failure to observe this could lead to fires.

CAUTION

∙Vacuum the inverter with a vacuum cleaner to clean it. Do not use organic solvents. Failure to observe this could lead to fires or damage.

5. Others

DANGER

∙Never modify product.

Failure to observe this could lead to electrical shocks or injuries.

CAUTION

∙ Dispose of this product as industrial waste.
