Wiring; Operation - GE VAT2000 Instruction Manual

2. Wiring

• 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.
• 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

• 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.
