Do not refit the inverter unauthorized; otherwise fire, electric shock or
other injury may occur.
The base of the radiator may become hot during running. Do not
touch to avoid hurt.
The electrical parts and components inside the inverter are
electrostatic. Take measurements to avoid electrostatic discharge
during relevant operation.
1.3.1 Delivery and installation
Please install the inverter on fire-retardant material and keep the
inverter away from combustible materials.
Connect the braking optional parts (braking resistors, braking units or
feedback units) according to the wiring diagram.
Do not operate on the inverter if there is any damage or components
loss to the inverter.
Do not touch the inverter with wet items or body, otherwise electric
shock may occur.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the
inverter and avoid physical injury or death. For physical safety, the erector should take some
mechanical protective measurements, such as wearing exposure shoes and working
uniforms.
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the inverter by its cover. The cover may fall off.
Install away from children and other public places.
The inverter cannot meet the requirements of low voltage protection in IEC61800-5-1 if the
sea level of installation site is above 2000m.
The leakage current of the inverter may be above 3.5mA during operation. Ground with
proper techniques and ensure the grounding resistor is less than 10Ω. The conductivity of PE
grounding conductor is the same as that of the phase conductor (with the same cross
sectional area).
R, S and T are the input terminals of the power supply, while U, V and W are the motor
terminals. Please connect the input power cables and motor cables with proper techniques;
otherwise the damage to the inverter may occur.
1.3.2 Commissioning and running
Disconnect all power supplies applied to the inverter before the
terminal wiring and wait for at least the designated time after
disconnecting the power supply.
High voltage is present inside the inverter during running. Do not carry
out any operation except for the keypad setting.
The inverter may start up by itself when P01.21=1. Do not get close to
the inverter and motor.
The inverter can not be used as “Emergency-stop device”.
The inverter can not be used to break the motor suddenly. A
mechanical braking device should be provided.
