I. Product confirmed
Thank you for using Mini series inverter. When unpacking, please confirm carefully whether there is damage
or damage during transportation, and whether the plate of this machine is in accordance with your ordering
requirements.
If you find any problems, please contact the supplier or our company directly.
II. Attention & Safety
☞Damaged inverters and inverters run out of parts should NOT be installed.
☞Please install on non-combustible material such as metal plate.
☞When two or more inverters are installed in the same control cabinet, set the cooling fan and keep the
temperature of the air inlet below 40 ℃.
☞Do not conduct voltage withstand test on the inverter.
☞Please electrical engineering professionals for wiring operations, non-professional and technical personnel,
please do NOT carry out maintenance and inspection work.
☞Before wiring, make sure the input power is off.
☞Be sure to install the terminal cover before turning on the power. When removing the cover, be sure to turn
off the power.
☞Grounding terminal must be grounded reliably.
☞Do not touch the inverter's terminals, there is high voltage on the terminals.
III. Installation environment requirements
(1) In a well-ventilated indoor place, the ambient temperature should be within the range of -10ºC ~ 40ºC. If
the temperature exceeds 40ºC, external forced cooling or derating is required.
(2) to avoid installation in direct sunlight, more dust, there are floating fibers and metal powder place.
(3) Do not install in a place with corrosive and explosive gas.
(4) Humidity less than 95% RH, no condensation of water droplets.
(5) Installed in a place where the vibration of plane fixed vibration is less than 5.9m / s² (0.6G).
(6) Keep away from sources of electromagnetic interference and other electronic equipment sensitive to
electromagnetic interference.

VIII. Troubleshooting
Fault Alarm and Troubleshooting
When the inverter is abnormal, protection function acts: LED displays fault code and the content, fault relay acts,
the inverter stops output and the motor coasts to stop. Mini series inverter’s fault contents and troubleshooting
is shown in Table 7-1. After fault alarm occurs, fault phenomenon should be recorded in detail, the fault should
be processed according to Table 7-1. When in need of technical assistance, please contact your supplier.

Fault Record Search
This series inverter record the fault codes occurred in the last 6times and inverter running parameter when
last fault occurred. The fault information is saved in P6 group.
Fault Reset
When fault occurred, please select the following methods to recover:
(1) When fault code is displayed, after ensure it can be reset, press key to reset.
(2) Set any one of X1~X8 terminal as external RESET input (P4.00~P4.07=17).
(3) Cut off power.

Attention
(1) Reset the inverter after thoroughly investigating the cause of fault and clearing, otherwise, the inverter
may be damaged.
(2) If it can’t be reseted or fault occurs again after reset, please check the cause of fault, continuous reset
may damage inverter.
(3) Reset the inverter after waiting for 5min when overload or overheat protection occurs.
