Safety Precautions

1. Electric Shock Prevention

WARNING

• While power is on or when the inverter is running, do not open the front cover. Otherwise, you may get an electric shock.

• Do not run the inverter with the front cover or wiring cover removed. Otherwise, you may access the exposed highvoltage terminals and charging part and get an electric shock.

• If power is off, do not remove the front cover except for wiring or periodic inspection. You may access the charged inverter circuits and get an electric shock.

• Before starting wiring or inspection, check to make sure that the indication of the inverter operation panel is off, wait for at least 10 minutes after the power supply has been switched off, and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power off and it is dangerous.

• Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work.

• Always install the control terminal option before wiring.

Otherwise, you may get an electric shock or be injured.

• Do not touch the control terminal option with wet hands.

Otherwise, you may get an electric shock.

• Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.

2. Injury Prevention

CAUTION

• Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur.

• Ensure that the cables are connected to the correct terminals.

Otherwise, burst, damage, etc. may occur.

• Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst, damage may occur.

• While power is on or for some time after power-off, do not touch the inverter as they will be extremely hot. Doing so can cause burns.

3. Additional Instructions

Also note the following points to prevent an accidental failure, injury, electric shock, etc.

(1) Transportation and mounting

• Do not install or operate the terminal block option unit if it is damaged or has parts missing.

• Do not stand or rest heavy objects on the product.

• Check that the mounting orientation is correct.

• Prevent other conductive bodies such as screws and metal fragments or other flammable substance such as oil from entering the inverter.

(2) Trial run

CAUTION

• Before starting operation, confirm and adjust the parameters.

A failure to do so may cause some machines to make unexpected motions.

(3) Usage

WARNING

• Do not modify the equipment.

• Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the product.

CAUTION

• When parameter clear or all parameter clear is performed, reset the required parameters before starting operations.

Each parameter returns to the initial value.

• For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity from your body.

(4) Maintenance, inspection and parts replacement

CAUTION

• Do not test the equipment with a megger (measure insulation resistance).

(5) Disposal

CAUTION

• Treat as industrial waste.

(6) General instruction

All illustrations given in this manual may have been drawn with covers or safety guards removed to provide in-depth description. Before starting operation of the product, always return the covers and guards into original positions as specified and operate the equipment in accordance with the inverter manual.
