High-function General-purpose Inverter RX2 Series User’s Manual
The following describes the wiring for the inverter output terminals (U/T1, V/T2, W/T3).
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.
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.
Do Not Use Phase Advance Capacitors/noise Filters
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.
Do Not Use Magnetic Switches
Do not connect any magnetic switches or magnet contactor to the output circuit.
If a load is connected to the inverter in operation, the inverter’s overcurrent protection circuit is acti-
vated due to the inrush current.
Precautions for Connecting More Than One Motor to Inverter’s Output Termi-
nals
If connecting more than one motor to the output terminals of the inverter, note the following three
points.
• Make sure that the ND-rated current (Normal Duty) of the inverter is higher than the sum of the
rated current values of the connected motors. Select an inverter with a sufficient capacity, taking
emergency situations into consideration.
• 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.
