Circuit Breaker

Recommended:

NF series

Always install a circuit breaker on the power-supply

side to protect the power supply system and to prevent

an overload at the occurrence of a short-circuit.

Absorbs the open / close surge of electro-magnetic contactors

and control relays. Always insert the surge suppressor on

magnetic contactors and relays near the inverter.

CR2LS series

CR6L series

CM, CMS series

Fuse / Fuse Holder

Protects internal circuitry in the event of component failure.

Fuse should be connected to the input terminal of the drive.

Note : Refer to the instruction manual for information on UL approval.

Isolates the inverter input / output signal,

and is effective to prevent inductive noise.

Reduces noise circulating to the inverter input

power system, or originating from the wiring.

Insert the filter as near the inverter as possible.

Reduces noise from the line that sneaks into the

inverter input power system. Insert as close to

the inverter as possible.

Can be used on both the input side and output side.

Reduces noise originating from the output side wiring of the

inverter. Insert the filter as near the inverter as possible.

Shortens the deceleration time by consuming the regenerative

energy of the motor by the resistor. (Use rate 3 ％ ED)

Shortens the deceleration time by consuming the regenerative

energy of the motor by the resistor. (Use rate 10 ％ ED)

Used in combination with the braking resistor unit

to reduce the deceleration time of the motor.

Applied to improve the input power ratio of the inverter.

The Varispeed G7 incorporates DC reactor on model of

18.5 kW or more (option for model 15 kW or less).

When using large power supply capacity (600 kVA or

more), also install the DC reactor or AC reactor.

When braking resistor is attached, install the contactor to prevent the

braking resistor from burning. Also inset a surge suppressor on the coil.

Always install a GFI on the power-supply side to protect the power supply system

and to prevent an overload at the occurrence of shortcircuit, and to protect the drive

from ground faults that could result in electric shock or fire.

Note: When a GFI is installed for the upper power supply system, an MCCB can be

used instead of a GFI. Choose a GFI designed to minimize harmonics specifically

for AC drives. Use one GFI per drive, each with a current rating of at least 30 mA.
