1.2 Safety Precautions

1.2 Safety Precautions

● Please make confirmation when the product is in hand.

 Notes

1. Don’t install damaged inverter and inverter lacking components and parts.

  Prevent causing personal injury.

●Installation

Notes

1. Please hold the base of body in transportation.

It may have danger of body falling and hurting your feet if only holding the panel.

2. Please install the equipment on metal panel and other nonflammable material panels.

It may have danger when it is installed on flammable materials.

3. When two or more inverters are installed in the same control cabinet, please set cooling fan and maintain the air temperature of inlet below 40℃.

Due to overheating, it may cause fire disaster and other accidents.

● Wiring

Danger

1. Please confirm the input power has been cut before wiring.

It may have danger of electric shock and fire.

2. Please ask professional electrical engineering personnel to take wiring operation.

It may have danger of electric shock and fire.

3. The earthing terminal must be earthed reliably.

It may have danger of electric shock.

4. After emergency shutdown terminal is connected, it must check whether its action is effective.

It may have danger of injury. (Wiring responsibilities shall be undertaken by the user.)

5. Don’t touch the output terminal directly. The output terminal of inverter shall not be connected with the shell. Don’t connect short circuit between terminals.

It may have danger of electric shock and causing short circuit.

 

Notes

1. Please confirm whether AC main circuit power is consistent with the rated voltage of inverter.

It may have danger of injury and fire.

2. Don’t take withstand voltage test for inverter.

It may cause damage of semiconductor components.

3. Please connect brake resistor or brake unit according to the wiring diagram.

It may have danger of fire.

4. Please use screwdriver with appointed moment to fasten terminals.

It may have danger of fire.

5. Don’t connect input power wires on output U, V and W terminals.

It may cause internal damage of inverter if voltage is added on output terminals.

6. Don’t connect phase shifting capacitor and LC/RC noise filter on output circuit.

It may cause internal damage of inverter.

7. Don’t connect solenoid switch and electromagnetic contactor on output circuit.

During the load operation of inverter, surge current produced by the action of solenoid switch and electromagnetic contactor may cause loop action of over-current protection of the inverter.

● Maintenance and Inspection

Danger

1. Don’t touch the wiring terminal of inverter. It has high voltage on terminals.

It may have danger of electric shock.

2. Before powering on, make sure the panels are installed properly. When disassembling the panels, it must cut off the power.

It may have danger of electric shock.

3. Don’t take maintenance and inspection operation for non professional technicians.

It may have danger of electric shock.

 

Notes

1. CMOS integrated circuit is installed on keyboard, control circuit board and driving circuit board. It shall pay special attention when using. Electrostatic induction may damage the integrated chip on the circuit board if using finger to touch the circuit board directly.

2. Don’t change wires and disassemble terminal wires in powering on process.

Don’t inspection signals in operation process, as it may damage the equipment.
