1.2 Safety Operation Attentions
1. Installation and maintenance should be performed by professional only.
2. Verify that rated voltage of the frequency inverter should conform with voltage
level of AC power supply. Otherwise it shall cause hurt to human body or fire
accident.
3. Don’t connect main circuit power with output terminals U, V and W. The
connection will damage equipment, thus warranty cardwill be invalid.
4. Don’t connect input power until panel is well installed. Do not remove the
cover when it is powered; otherwise, electric shock may occur.
5. Don’t touch high voltage terminal within frequency inverter under power-on status;
otherwise, electric shock may occur.
6. Maintain the frequency inverter after powering off it for at least 15 minutes
because it has plenty of capacitance energies. At the moment, charging indicator light
will be off or confirm the positive and negative Bus line voltages are under 36V;
otherwise, electric shock can occur.
7. Don’t turn on or off line and connector when the circuit is powered on Otherwise,
personal injury may occur.
8. Electronic components can be easily damaged by static electricity so please avoid
touching them.
9. This frequency inverter should not undergo voltage withstand test, which might
result indamages to the semiconductor devices in it.
10. Cover plate must be covered up before power on; otherwise, electric shock and
explosion can occur.
11. Never confuse the input and output terminals. Otherwise, explosion or damage to
the property mightoccur.
12. For frequency inverter of which storage period exceeds half year, please increase
the input voltage gradually by using regulator, to prevent from electric shock and
explosion.
13. Don’t operate the frequency inverter with wet hands; otherwise, electric shock
may occur.
14. All parts should be replaced by professional only. It is strictly prohibitive to
remain stub ormetal object in machine, to prevent from fire.
15. After replaced control board, please perform relevant parameter setting before
operation toprevent from damage of materials.
Cautions
1. If the motor is used for the first time or has been in leisure for a long time,
remember tocheck its insulation first. It is advisable to use a 500V megger. Make sure
the insulationresistance should not be less than 5 MΩ.
2. Please consider the tolerance of mechanical device if it needs running above 50 Hz.
3. In the regions with an altitude above 1,000 m, the heat dissipation effect of
frequency inverter will be reduced due to thin air so it must be used with a reduced
capacity. Reduce capacity by 1% for every 100 m after the altitude exceeds 1,000 m.
4. Do not start or stop the frequency inverter with contactors. Otherwise, damage
might occurto the equipment.
5. Do not modify factory set value of frequency inverter without authorization, or
damagemight be caused.
