Main power supply

In the following examples involving a general-purpose inverter, a large peak current flows on the main power supply side, and is able to destroy the converter module. Where such situations are foreseen or the connected equipment must be highly reliable, install an AC reactor between the power supply and the inverter. Also, where influence of indirect lightning strike is possible, install a lightning conductor.

(A)The unbalance factor of the power supply is 3% or higher. (Note)

(B)The power supply capacity is at least 10 times greater than the inverter capacity (the power supply capacity is 500 kVA or more).

(C)Abrupt power supply changes are expected. Examples:

Notes on Peripheral Equipment Selection

Wiring connections		(1) Be sure to connect main power wires with R(L1), S(L2), and T(L3) terminals (input) and motor wires to U(T1), V(T2), and W(T3)
		terminals (output). (Incorrect connection will cause an immediate failure.)
		(2) Be sure to provide a grounding connection with the ground terminal (	).


	Electromagnetic	When an electromagnetic contactor is installed between the inverter and the motor, do not perform on-off switching during running
	contactor	operation.
Wiring		When used with standard applicable output motors (standard three-phase squirrel-cage four-pole motors), the X200 Series does not
		need a thermal relay for motor protection due to the internal electronic protective circuit. A thermal relay, however,
between
		should be used:
inverter and
	Thermal relay	• during continuous running outside a range of 30 to 60 Hz.
motor		• for motors exceeding the range of electronic thermal adjustment (rated current).

•when several motors are driven by the same inverter; install a thermal relay for each motor.

•The RC value of the thermal relay should be more than 1.1 times the rated current of the motor. Where the wiring length is 10 m or more, the thermal relay tends to turn off readily. In this case, provide an AC reactor on the output side or use a current sensor.

	Installing a circuit breaker	Install a circuit breaker on the main power input side to protect inverter wiring and ensure personal safety. Choose an inverter-
	Installing a circuit breaker	compatible circuit breaker. The conventional type may malfunction due to harmonics from the inverter. For more information, consult
		the circuit breaker manufacturer.

	IWiring distance	The wiring distance between the inverter and the remote operator panel should be 20 meters or less. When this distance
	IWiring distance	isexceeded, use CVD-E (current-voltage converter) or RCD-E (remote control device). Shielded cable should be used on thewiring.
		Beware of voltage drops on main circuit wires. (A large voltage drop reduces torque.)

	Earth leakage relay	If the earth leakage relay (or earth leakage breaker) is used, it should have a sensitivity level of 15 mA or more (per inverter).
	Phase advance capacitor	Do not use a capacitor for power factor improvement between the inverter and the motor because the high-frequency components of

High-frequency Noise and Leakage Current

(1)High-frequency components are included in the input/output of the inverter main circuit, and they may cause interference in a transmitter, radio, or sensor if used near the inverter. The interference can be minimized by attaching noise filters (option) in the inverter circuitry.

(2)The switching action of an inverter causes an increase in leakage current. Be sure to ground the inverter and the motor.

Lifetime of Primary Parts

Because a DC bus capacitor deteriorates as it undergoes internal chemical reaction, it should normally be replaced every five years. Be aware, however, that its life expectancy is considerably shorter when the inverter is subjected to such adverse factors as high temperatures or heavy loads exceeding the rated current of the inverter.The approximate lifetime of the capacitor is as shown in the figure at the right when it is used 12 hours daily (according to the " Instructions for Periodic Inspection of General-Purpose Inverter " (JEMA).)Also, such moving parts as a cooling fan should be replaced. Maintenance inspection and parts replacement must beperformed by only specified trained personnel.
