Grounding:
The drive contains high power and high frequency switching devices, leakage current
•
may flow between the drive and ground. Ground the drive to avoid electrical shock.
If multiple drives are installed near each other, each must be connected to ground
•
directly. Take care not to form a ground loop between the drives and the grounding
location.
The protective earth conductor must be the first one in being connected and the last one
•
in being disconnected.
The grounding wire shall comply with all local regulations. As a minimum,The
•
grounding wire should be at least the thickness that is listed in the following table and as
short as possible. Connect the grounding point as near to the drive as possible.
Use the Type 3 grounding method (Ground impedance: Below 100W) for 230V class
•
drives.
Use the Special Type 3 grounding method (Ground impedance: Below 10W) for 460V
•
class drives.
Use the dedicated ground terminal to ground the drive. Do not use the screw in the case
•
or chassis, etc. for grounding.
Grounding Procedure:
Remove the front cover.
•
Connect the grounding wire to the ground terminal through the opening for ground
•
terminal as shown above. Enter the screw driver from vertical to the terminal and secure
the screw tightly.
