Chapter 1 Safety Precautions
1.1 Before supplying power
Warning
¾ The main circuit must be properly wiring. Single phase( R/L1, S/L2)/3-phase(R/L1,
S/L2, T/L3) are the input terminal of the power, which must not be mixed with
U/T1,V/T2 and W/T3 on use. In case of mixed use, supplying power will damage the
inverter.
Caution
¾ The power voltage must be the same as the input voltage of the inverter.
¾ When handling the inverter, do not draw the front cover directly. It is suggested to
handle the inverter body so as to prevent the front cover breaks off, avoiding the
inverter falling and causing injury or inverter damage.
¾ Please mount the inverter on noncombustible materials such as metal. Mounting on or
near the flammable materials is not allowed in case fire happened.
¾ If several inverters are mounted on a single control panel, the extra cooling fan shall
be added, so as to make the panel temperature below 40 ℃ and to prevent
overheating or fire.
¾ Please firstly turn off the power before disassemble or assemble the operator. Fix the
operator according to the indicating diagram to avoid operation failure or no display
due to improper operation.
