3. OVER LOAD PROTECTION
IOLT: IOLT(inverter Overload Trip) protection is activated at 110% of the inverter rated current for 1
minute and greater.
OLT : Inverter shuts off its output when inverter output current exceeds its overload trip level for
overload trip time. OLT is selected when FU1-66 is set to “Yes” and activated at 120% of FU1-67
[Motor rated current] for 60 sec set in FU1-68.
4. OVER SPEED PROTECTION
Not Provided With Overspeed Protection.
5. FIELD WIRING TERMINAL
1) Use copper wires only with 600V, 75 ratings ℃
2) Tightening torque of power terminal blocks

Apply the rated torque to terminal screws. Loose screws can cause of short circuit or malfunction. Tightening the screws too
much can damage the terminals and cause a short circuit or malfunction.
3) For 7.5~11kW 240V type inverters, Input and motor output terminal blocks are intended only for
use with ring type connectors.
