! E6581301 ■■■■ Wiring I Reference Warning • Do not connect input power to the output (motor side) terminals (U/T1,V/T2,W/T3) of the 2.2 inverter. Doing so will destroy the inverter and may result in fire. 2.2 • Do not connect resistors to the DC terminals (e.g., PA/+ and PC/-, or PO and PC/-). 5.19 That may cause a fire. Connect resistors as directed by the instructions for “Installing separate braking resistors.” Prohibited • Within 15 minutes after turning off input power, do
