Use within the allowable power
supply specification of the
controller.
Select a proper breaker to resist
large in-rush current that flows into
the controller at power-on.
To guarantee safety, use an
electromagnetic contactor. Do not
use it to start or stop the controller
because such operation reduces
the service life of the controller.
Suppress the high order harmonic
to improve the power factor.
Reduce the
electromagnetic
interference on the
input side.
Reliably ground the
motor and the
controller to prevent
electric shock.

1. Do not install the capacitor or surge suppressor on the output side of the controller.
Otherwise, it may cause faults to the controller or damage to the capacitor and surge
suppressor.
2. Inputs/Outputs (main circuit) of the controller contain harmonics, which may interfere
with the communication device connected to the controller. Therefore, install an anti-
interference lter to minimize the interference.
3. Select the peripheral devices based on actual applications as well as by referring to
section 3.8.2.
The following table describes the peripheral electrical devices.
