1.3 Safety guide
Only qualified electricians are allowed to operate on the inverter.
Do not carry out any wiring, inspection or component replacement when
the power supply is applied. Ensure all input power supply is disconnected
before wiring and checking and always wait for at least the time designated
on the inverter or until the DC bus voltage is less than 36V. The table below
describes the waiting time:
Do not refit the inverter unless authorized; 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 related
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 optional brake 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.
