2WIRINGMain circuit terminal specifications2.2 Main circuit terminal specifications2.2.1 Specification of main circuit terminalTerminalSymbolTerminal NameDescriptionR/L1,S/L2, AC power input Connect to the commercial power supply.T/L3U, V, W Inverter output Connect a three-phase squirrel-cage motor.R1/L11,S1/L21Power supply forcontrol circuitConnected to the AC power supply terminals R/L1 and S/L2. To retain thefault 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 themain circuit power (R/L1, S/L2, T/L3) on. Doing so may damage theinverter. 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 ormore is 100VA.P/+, N/- DC terminal Do not connect any options.Earth (Ground)For earthing (grounding) the inverter chassis. Must be earthed(grounded).15
