|
| • | Electrical construction work must be done by a qualified expert. | 2.1 |
|
|
|
|
|
| Connection of input power by someone who does not have that expert knowledge may re- |
|
|
|
|
|
|
| sult in fire or electric shock. |
|
|
|
|
|
| • | Connect output terminals (motor side) correctly. | 2.1 |
|
|
|
|
|
| If the phase sequence is incorrect, the motor will operate in reverse and that may result in |
|
|
|
|
|
|
| injury. |
|
|
|
|
|
| • | Wiring must be done after installation. | 2.1 |
|
|
|
|
|
| If wiring is done prior to installation that may result in injury or electric shock. |
|
|
|
|
|
| • | The following steps must be performed before wiring. | 2.1 |
|
|
|
| Mandatory |
| (1) Turn off all input power. |
|
|
|
|
|
| (2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit. |
|
| |
|
|
|
|
| (3) Use a tester that can measure DC voltage (800VDC or more), and check to make sure |
|
|
|
|
|
|
| that the voltage to the DC main circuits (across |

|
|
|
|
| If these steps are not properly performed, the wiring will cause electric shock. |

|
| • | Tighten the screws on the terminal board to specified torque. | 2.1 |
|
|
|
|
|
| If the screws are not tightened to the specified torque, it may lead to fire. |
|
|
|
|
|
| • | Check to make sure that the input power voltage is +10%, | 1.4.4 |
|
|
|
|
|
| age written on the rating label (± 10% when the load is 100% in continuous operation) |
|
|
|
|
|
|
| If the input power voltage is not +10%, |
|
|
|
|
|
|
| load is 100% in continuous operation) this may result in fire. |
|
|
|
|
|
| • | Ground must be connected securely. | 2.1 |
|
|
|
|
|
| If the ground is not securely connected, it could lead to electric shock or fire when a mal- | 2.2 |

| • Do not touch inverter terminals when electrical power is going to the inverter even if the | 3. | |
| motor is stopped. |
| |
| Touching the inverter terminals while power is connected to it may result in electric shock. |
| |
| • Do not touch switches when the hands are wet and do not try to clean the inverter with a | 3. | |
Prohibited | damp cloth. Such practices may result in electric shock. |
| |
• Do not go near the motor in | 3. | ||
| |||
| The motor may suddenly restart and that could result in injury. |
| |
| Take measures for safety, e.g. attaching a cover to the motor, against accidents when the |
| |
| motor unexpectedly restarts.. |
| |
| • Turn input power on after attaching the front cover. | 3. | |
| When storing inside the cabinet and using with the front cover removed, always close the |
| |
| cabinet doors first and then turn power on. If the power is turned on with the front cover or |
| |
Mandatory | the cabinet doors open, it may result in electric shock. |
| |
• Make sure that operation signals are off before resetting the inverter after malfunction. | 3. | ||
| If the inverter is reset before turning off the operating signal, the motor may restart sud- |
| |
| denly causing injury. |
