Power
source
Please use within the permissible
power supply for the drive.
When the power is ON, a large in-
rush current flow will be inputted into
the drive. The breaker must be
selected carefully.
Option. When it is used for external
control or the DBU is used, it should be
installed at the primary side. Do not use
MC to start/stop the drive, otherwise the
life of drive will be
reduced.
Reduce the harmonic
interference for low frequency
of power.
Reduce conduction
interference.
Reduce radiation interference.
The range of limited frequency
is 1MHz - 10MHz.

The ACL can
reduce the leakage
current of motor
effectively; It is
used as the motor
is far away from the
drive.
Reduce radiation
interference.
The range of limited
frequency is
1MHz - 10MHz.

CAUTION
1. When the drive requires the following equipment, please select the proper external
equipment. The incorrect system setup will result the failure of drive, reduce the of
drive’s service life time, and even damage the drive.
2. The surrounding temperature will influence
drive’s service life time. Please monitor the
temperature to avoid of exceeding the temperature specifications, especially as drive
installed at a closed place. In addition, the control signal should be far away from main
loop to avoid of the signal interference.
3. The motor and drive should be grounded well to avoid of electric shocks. M
otor’s
grounding must connect to drive’s grounding terminal.
