● Turn the power off before wiring.
● After cutting off AC power, high voltage still exists in the inverter before the
charging indicator goes out, so it is dangerous to touch internal circuit and components.
● Don't check the components and signal on circuit board during operation.
● Don't dismantle or change the internal connection, wiring or components of inverter
at will.
● Don't control buttons with wet hands to avoid electric shock.
● Earthing terminal of the inverter shall be grounded properly.
● It is prohibited to change and replace the control panel and components at will so
as to prevent electric shock, explosion and other dangers.
● Since semiconductor parts inside the inverter are easily damaged by high voltage,
it is prohibited to perform voltage withstand test to them.
● It is prohibited to connect the output terminal U.V.W of inverter to AC power.
● Don't touch the inverter and brake resistor when the power is turned on or
disconnected before long in high temperature, so as to avoid scalding.
● Voltage applied to each terminal only can be that required in the Instruction Manual
to prevent bursting, damage and so on.
● Don't touch the main circuit boards CMOS and IC of the inverter since they are
easily influenced and damaged by static electricity.
● Only qualified professionals can install, debug and maintain the inverter.
● Scrapped inverter shall be disposed as industrial wastes, and burning is prohibited.
● After long-term storage, the inverter must undergo checking and commissioning
before being used.
● The inverter can be easily set for high-speed operation, before the setting, please
check whether the characteristics of motor and machine are suitable for such high-speed
operation.
