1. If the damage to frequency VFD or other equipment is caused by improper wiring and utilization or unauthorized alteration,
the user should shoulder all responsibilities.
2. Please make sure all wirings meet EMC requirement and satisfy safety standard in the local area; Please refer to
recommendations in this manual or national standards of wire diameter to avoid accidents.
3. Static electricity on human body would seriously damage internal MOS transistor, etc. No touch the printed circuit boards,
IGBT or other internal devices without anti-static measure, otherwise it will cause the malfunction of frequency VFD.
4. Please don't connect phase shifter capacitance or LC/RC noise filter to the output circuit of frequency VFD; Otherwise it
will damage the frequency VFD.
5. Please don't connect the magnetic switch or magnetic contactor to the output circuit of frequency VFD; When frequency
VFD is in the operation with load, magnetic switch or magnetic contactor can make VFD over-current protection function
act. It will damage frequency VFD seriously.
6. Please don't disassemble the panel cover, it only needs to disassemble the terminal cover when wiring.
7. It is forbidden to do any pressure test on frequency VFD, otherwise it will damage the frequency VFD.
●Before Electrification
1. Please make sure that voltage grade of power supply is consistent with frequency VFD's voltage and then check whether
the wiring is correct and firm, and whether there is short circuit in peripheral equipment's circuit. Otherwise it will damage
frequency VFD and other equipment.
2. Before the frequency VFD is connected to the input power supply, make sure that the cover has been well fixed. Otherwise
it will cause electric shock.
3. For the frequency VFDs whose storage time is over 1 year, when electrification, the voltage should be raised by booster
from low to high. Otherwise it will damage the frequency VFD.
1. Check if all periphery fittings are wired properly according to the handbook; Otherwise it will cause accidents.
●After Electrification
1. After electrified, it is forbidden to open the cover, make wiring, and check up; Otherwise, it will cause the danger of electric
shock.
2. After electrified, it is forbidden to contact internal wiring board and its parts. Otherwise it will cause the danger of electric
shock.
3. Do not operate or touch frequency VFD with wet hand. Otherwise there is danger of damage to frequency VFD and
electric shock.
1. Please set the parameter of frequency VFD cautiously; Otherwise it will damage equipment.
