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.

Please use the inverter on appropriate condition (See chapter Installation
Environment).

Don't allow screws, cables and other conductive items to fall inside the inverter.

The leakage current of the inverter may be above 3.5mA during operation. HIGH
LEAKAGE CURRENT, EARTH CONNECTION ESSENTIAL BEFORE CONNECTING
SUPPLY. 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).

Grounding conductors minimum cross-sectional area of at least 10mm
corresponding data in the table below, the maximum being asked to choose between
the two cross-sectional area as the grounding conductor:

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.
