Do not connect or disconnect wiring while the power is on.
Failure to comply will 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, and then measure the DC bus voltage
level to confirm it has reached a safe level.
Never connect or disconnect wiring, remove connectors or option cards, or replace the cooling fan while the power
is on.
Failure to comply will 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.

supply is turned off. After shutting off the power, wait for at least the amount of time specified on the drive before touching
any components.
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.
