DANGER
Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized drive. Before
servicing, disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal
capacitor stays charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus voltage
decreases below 50 Vdc. When all indicators are OFF, measure for dangerous voltages to make sure that the drive is safe. If
you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.
WARNING
Fire Hazard. Do not connect main power supply wiring to drive motor terminals U/T1, V/T2, and W/T3.
Connect main power supply wiring to main circuit input terminals R/L1, S/L2, and T/L3. Incorrect wiring can cause serious injury
or death from fire.
