Warning
Prohibited
•When transporting or carrying, do not hold by the front panel covers. The covers may come off and the unit will drop out resulting in injury.
2.1Cautions on wiring
Danger
•Never remove the front cover when power is on or open door if enclosed in a cabinet.
The unit contains many high voltage parts and contact with them will result in electric shock.
Prohibited |
|
| ||
|
|
| • | Turn power on only after attaching the front cover or closing door if enclosed in a cabinet. |
|
|
| ||
|
|
|
| If power is turned on without the front cover attached or closing door if enclosed in a cabinet. This can |
|
|
|
| result in electric shock or other injury. |
Mandatory |
| |||
• | Electrical construction work must be done by a qualified expert. | |||
|
|
|
| Connection of input power by someone who does not have that expert knowledge may result in fire or |
|
|
|
| electric shock. |
|
|
| • | Connect output terminals (motor side) correctly. |
|
|
|
| If the phase sequence is incorrect, the motor will operate in reverse and that may result in injury. |
|
|
| • | Wiring must be done after installation. |
|
|
|
| If wiring is done prior to installation that may result in injury or electric shock. |
|
|
| • | The following steps must be performed before wiring. |
|
|
|
| (1) Shut 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 PA/+ and |
|
|
|
| If these steps are not properly performed, the wiring will cause electric shock. |
|
|
| • | Tighten the screws on the terminal board to specified torque. |
|
|
|
| If the screws are not tightened to the specified torque, it may lead to fire. |
