Safety Precautions
User must obey to the following safety rules and related requirements while using the peripheral equipments and
selecting components.
●
No operation under power connected state. Otherwise, there is danger of electric
shock.
●
Before operation, please cut all related equipments power, ensure that the main circuit
DC current has dropped to safe range. And please operate after 5 mins.
●
No operation while cover/panel is dismantled. Otherwise, there is danger of electric
shock.
●
Do not dismantle the cover or PCB under power connected state. Otherwise, there is
danger of electric shock.
●
Only professional person can install, debug or maintain the peripheral equipments and
options. Otherwise, there is danger.
●
Do not ware loose clothes when install, debug, maintain. Rated protective tools and
safeguard should be adopted.
●
Do not change wire, dismantle jumping wire, optional card, or change cooling fan while
the inverter is running. Otherwise, there is danger of electric shock.
●
Tighten screw according to named torque. If main circuit wire connection is loose, there
is danger of overheat fire.
●
Earth of the peripheral equipments and options must be reliable to prevent human body
injury.
●
While operation, please follow the ESD regulations. Otherwise, the inverter maybe
damaged.
●
Do not cut the power supply while the inverter is outputting voltage. Otherwise, the
inverter maybe damaged.

Leakage current breaker
Earth protection prevent electric shock(suggest to use the
type which can prevent high-frequency leakage current)
Electromagnetic contactor
Separate power and inverter indeed and realize basic
relay control.
AC input reactor
Improve power side factor and isolate the noise
disturbance to the frequency inverter from the power side.
DC reactor
Restrain ultra harmonics and improve power factor.
Input side noise filter
Reduce frequency inverter disturbance to the power and
reduce the power grid disturbance.
Braking resistor
Passive energy consume unit of electric braking.
Consumption braking unit
Electric braking control unit, controlling the braking
resistance consume the regenerated electric power of the
motor efficiently.
Output side noise filter
Reduce the output side wire electromagnetic disturbance.
Standby system
Standby system for inverter malfunction.
Heat relay
Protect the motor while over load.
0-phase reactor
Reduce electromagnetic disturbance of the frequency
inverter (suitable for input/output side).
Main loop surge absorption unit
Restrain surge voltage while main loop switch components
act.
Winding surge absorption unit
Restrain surge voltage when the AC contactor acts.
