Ⅰ.SAFETY INSTRUCTIONS

1. NOTES FOR OPERATION

Before wiring
● Specification of applying power supply shall correspond to input voltage of the inverter.
● Main circuit terminals must be correct, L1/R, L2/ S and L3/ T is input terminals and it's forbidden to use
mixing with U, V and W. Failure to observe this may cause the inverter damaged.
● When delivering the inverter, do not take the cover directly. Take the air fan seat to prevent the cover
got off. Inverters getting off which may cause damage to personal or machine shall be avoided.
● Install the inverter on metal or other non-inflammable materials. Do not fix it on inflammable materials
which may cause a fire hazard.
● In case of several inverters are installed together in one control panel, a fan shall be prepared to make
sure temperature lower than 40℃, thus over-heating or a fire hazard shall be avoided.
● Make sure applied power supply comply with label showed on the right of the machine. Failure to
observe this may cause action failure.
During operation
● Never put in or take off the motor during operation, otherwise over-current even over burning the main
circuit of the inverter may happen.
● When auto-restart function is set, do not approach the machine since motor can be reset suddenly after
being stopped.
● The function set can make the stop key invalid, which is different from the emergency stop key. Please
pay attention to it.
● Never touch heat sink or discharging resistor since temperature may be very high.
● Since it is easy to change running speed from low to a high speed, verify safe working range of motor
and machine before running.
● Use brake unit according to the method described in wiring diagram.
● Do not check signals during running.
● All parameters of the inverter have been preset at the factory according to line frequency. Do not
change the setting value at will.
