Connect to the commercial power supply.
Connect a three-phase squirrel-cage motor.
Connected to the AC power supply terminals R/L1 and S/L2. To retain the
fault display and fault output, remove the jumpers from terminals R/L1-R1/
L11 and S/L2-S1/L21 and apply external power to these terminals.
Do not turn off the power supply for control circuit (R1/L11, S1/L21) with the
main circuit power (R/L1, S/L2, T/L3) on. Doing so may damage the
inverter. The circuit should be configured so that the main circuit power (R/
L1, S/L2, T/L3) is also turned off when the power supply for control circuit
(R1/L11, S1/L21) is off.
Power supply capacity for the 15K or less is 90VA and for the 18.5K or
more is 100VA.
Do not connect any options.
For earthing (grounding) the inverter chassis. Must be earthed
(grounded).
