Disposing unwanted inverters
1 ) The capacitors and PCB may explode when they are burnt.
2 ) Poisonous gas may be generated when the plastic parts like front
covers are burnt.
3 ) Please dispose the inverter as industrial refuse.
Requirement on residual current device ( RCD )
The inverter generates high leakage current during running, which
flows through the protective earthing ( PE ) conductor. Thus it is
necessary to install a type-B RCD at primary side of the power supply.
When selecting the RCD, you should consider the transient and
steadystate leakage current to the ground that may be generated at the
inverter startup and running. You can select a specialized RCD with the
function of suppressing high harmonics or a general-purpose RCD with
relatively large residual current.
High leakage current warning
The inverter generates high leakage current during running, which
flows through the PE conductor. Earth connection must be done before
connection of power supply. Earthing shall comply with local regulations
and related IEC standards.
Surge suppressor
The inverter has a built-in voltage dependent resistor ( VDR ) for
suppressing the surge voltage generated when the inductive loads
( electromagnetic contactor, electromagnetic relay, solenoid valve,
electromagnetic coil and electromagnetic brake ) around the inverter
are switched on or off. If the inductive loads generate a very high surge
voltage, use a surge suppressor for the inductive load or also use a
diode.
Do not connect the surge suppressor on the output side of the
inverter.
Adaptive motor
1 ) The standard adaptive motor is four-pole squirrel-cage
asynchronous induction motor. If it is not the motor mentioned above,
