WARNING! Electrical Shock Hazard. Do not touch any terminals before the
capacitors have fully discharged. Failure to comply could result in death or serious
injury. Before servicing, disconnect all power to the equipment. The internal
capacitor remains charged even after the power supply is turned off. The charge
indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent
electric shock, wait for at least the time specified on the warning label, once all
indicators are OFF, measure for unsafe voltages to confirm the drive is safe prior
to servicing.
Switch the wires for T1 and T2 on the output terminals of the motor overload relay. Re-
tighten the terminal lugs and reapply power.
