WARNING
Do not touch any terminals before the capacitors have fully discharged.
Failure to comply could result in death or serious injury.
Before wiring terminals, 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 at
least one
minute after all indicators are off and measure the DC bus voltage level to confirm
safe level.
Fire Hazard
Tighten all terminal screws to the specified tightening torque.
Loose electrical connections could result in death or serious injury by fire due to overheating
of electrical connections.
Do not use an improper voltage source.
Failure to comply could result in death or serious injury by fire.
Verify that the rated voltage of the drive matches the voltage of the incoming power supply
before applying power.
Do not use improper combustible materials.
Failure to comply could result in death or serious injury by fire.
Attach the drive to metal or other noncombustible material.
