Multi-function Compact Inverter 3G3MX2-V1 User’s Manual (I585-E1)
The following describes the wiring for the inverter output terminals (U/T1, V/T2, W/T3).
z
Never connect power supply to output terminals
Never connect the power supply to the output terminals U/T1, V/T2, W/T3.
The inverter is damaged internally if power supply voltage is applied to the output terminals.
z
Never short or ground output terminals
Do not touch the output terminals with bare hand or contact the output wires with the inverter’s case.
Doing so may result in electric shock or ground fault.
Be careful not to short the output wires.
z
Do not use phase advance capacitors and noise filters for general-purpose
power supplies or for the input side
Never connect a phase advance capacitor or LC/RC noise filter for general-purpose power supplies
to the output circuit.
Doing so may result in damage to the inverter or burnout of these parts.
z
Do not use magnetic switches
Do not connect any magnetic switch or magnet contactor to the output circuit.
If a load is connected to the inverter when running, the inverter’s overvoltage protection circuit is
activated due to the inrush current.
z
Precautions for connecting more than one motor to inverter’s output termi-
nals
If connecting more than one motors to the output terminals of the inverter, note the following three
points.
• Make sure that the rated current of the inverter is higher than the sum of the rated current values
of the connected motors.
• The inverter cannot provide overload protection for individual motors, because it only detects a
sum of the current values for all the connected motors.
Install a thermal relay for each motor. The RC value of each thermal relay must be 1.1 times larger
than the rated current of the motor.
• Set the inverter to detect only overloading that occurred in it by setting the Electronic Thermal
Level to the rated output current of the inverter.
