Chapter VI. Operation Guide
Proper operating procedures allow you to use the frequency converter more smoothly and avoid unnecessary
troubles.
1.
Make sure the POWER ON switch is on OFF position.
2.
Make sure the switches, rotary buttons, displays are not loosen or damaged.
3.
Make sure the power supply is matching with the frequency converter specifications (110V, 220V etc.)
before turning the input POWER ON switch to ON position.
4.
Set the output frequency by "FREQUENCY SET" switch. Note, press OFF/RESET for setting hundreds
frequency (1xx.x).
5.
Choose the Low/High Voltage output voltage according to the loads, for
≤
150V change 0-150V (low) and
1-
300V (high) base on required voltage.
6.
Press to POWER ON switch (ON).
7.
Connect loads cable and turn on the AC OUTPUT switch to obtain required standard AC power supplies.
8. F
requency converter has overcurrent (overload), over temperature, short circuit, instantaneous power
off
protection and warning indicators. In case of above phenomenon happens, the protection circuit cut off
output immediately and trigger warning buzzer.
9.
Press OFF / RESET switch to cut off the output.
Caution: For 30kVA frequency converter (and above), to switch Low/High voltage, if the frequency
converter is connected loads, the frequency converter must be powered off and turn off the output switch
before switching the voltage.
