4.Multi-function analog output should be used for monitoring meters (e.g. output frequency meter)

and should not be used for feedback control system.

3.2 WIRING THE MAIN CIRCUIT

WA R NI N G

●Make sure to ground the ground terminal (Ground resistance 220V class：100Ω or less. 440V class：10Ω or less)

Failure to observe this warning can result in an electrical shock or a fire.

CAUTION

●Never connect the AC main circuit power supply to output terminals U,V and W.

The inverter will be damaged and invalidate the guarantee.

(1)Wiring Precautions for Main Circuit Input

(a)Installation of Molded-case Circuit Breaker (MCCB)

Make sure to connect MCCBs of fuses between AC main circuit power supply and TG-300 input

terminals L1, L2 and L3 to protect wiring.

(b)Installation of Ground Fault Interrupter

When connecting a ground fault interrupter to input terminals L1, L2 and L3, select one that is not

affected by high frequency.

(c)Installation of Magnetic Contactor

Inverters can be used without a magnetic contactor (MC) installed at the power supply side. When

the main circuit power supply is shut OFF in the sequence, a magnetic contactor (MC) can be used

instead of a molded-case circuit breaker (MCCB). However, when a magnetic contactor is switched

OFF at the primary side, regenerative braking does not function and the motor coasts to a stop.

● The load can be operated/stopped by opening/closing the magnetic contactor at the primary side.

However, frequent switching may cause the inverter to malfunction.

● When using a braking resistor unit, use a sequencer to break power supply side on overload relay

trip contact. If the inverter malfunctions, the braking resistor unit may be burned out.

(d)Terminal Block Connection Sequence

Input power supply phases can be connected to any terminal regardless of the order of L1, L2 and L3

on the terminal block.

(e)Installation of AC Reactor

When connecting an inverter (220V/440V 15Kw or less) to a large capacity power supply

transformer (600Kva or more), or when switching a phase advancing capacitor, excessive peak

current flows in the input power supply circuit, which may damage the converter section. In such

cases, install a DC reactor (optional) between inverter 1 and 2 terminals or an AC reactor

(optional) on the input side. Installation or a reactor is effective for improvement of power factor on

the power supply side.

(f)Installation of Surge Suppressor

For inductive loads (magnetic contactors, magnetic relays, magnetic valves, solenoids, magnetic

brakes, etc.) connected near the inverter, use a surge suppressor simultaneously.

(g)Prohibition of Installation of Phase Advancing Capacitor

If a phase advancing capacitor or surge suppressor is connected in order to improve the power factor,

it may become overheated and damaged by inverter high harmonic components. Also, the inverter

may malfunction because of overcurrent.

(2)Wiring Precautions for Main Circuit Output

(a)Connection of Terminal Block and Load

Connect output terminals U, V and W to motor lead wires U, V and W. Verify that the motor rotates in the forward direction (CCW：counterclockwise when viewed from the motor load side) with the

forward run command. If the motor rotation is incorrect, exchange any two of output terminals U,V

or W.

(b)Strict Prohibition of Connection of Input Power Supply to Output Terminals

Never connect input power supply to output terminals U, V and W.

(c)Strict Prohibition of Short Circuiting or Grounding of Output Circuit

Never touch the output circuit directly or put the output line in contact with the inverter case.

Otherwise, it may cause an electrical shock or grounding. In addition, never short circuit the output

line.

(d)Prohibition of Connection of Phase Advancing Capacitor or LC/RC Noise Fitter

Never connect a phase advancing capacitor or LC/RC noise, filter to the output circuit.

(e) Avoidance of Installation of Magnetic Starter

Do not connect a magnetic starter or magnetic contactor to the output, circuit.

If the load is connected while the inverter is running, the inverter overcurrent

protective circuit operates because of inrush current.

(f) Installation of Thermal Overload Relay

An electronic overload protective function is incorporated into the inverter.

However, connect a thermal overload relay when driving several motors with one inverter or when

using a multi-pole motor. When using a thermal overload relay, set inverter constant H033 to 0.

Additionally, for thermal overload relay, at 50Hz set the same rated current value as that described

on the motor nameplate, or at 60Hz 1.1 times larger than the rated current value described on the

motor nameplate.

(g) Wiring Distance between Inverter and Motor

If the total wiring distance between inverter and motor is excessively long and the inverter carrier

frequency (main transistor switching frequency) is high, harmonic leakage current from the cable

will adversely affect the inverter and peripheral devices.

If the wiring distance between inverter and motor is long, reduce the inverter carrier frequency as

described below. Carrier frequency can be set. by constant H050.

Wiring Distance between Inverter and Motor

(3)Grounding

●Ground resistance 220 V class：100Ω or less, 440 V class：10Ω or less

●Never ground TG-300 in common with welding machines, motors, or other large-current electrical

equipment. Run all the ground wires in a conduit separate from wires for large-current electrical

equipment.

●Use the ground wires described in tables below and keep the length as short as possible.

●When using several TG-300 units side by side, ground the units as shown below
