Electrical Installation
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, remove the covers before measuring 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
Electrical Shock Hazard. De-energize the drive and wait 5 minutes minimum until the Charge LED turns off.
Remove the front cover and terminal cover to do work on wiring, circuit boards, and other parts. Use terminals for their correct
function only. Incorrect wiring, incorrect ground connections, and incorrect repair of protective covers can cause death or serious
injury.
WARNING
Electrical Shock Hazard. Correctly ground the drive before you turn on the EMC filter switch. If you touch electrical
equipment that is not grounded, it can cause serious injury or death.
WARNING
Electrical Shock Hazard. Use the terminals for the drive only for their intended purpose. Refer to the technical
manual for more information about the I/O terminals. Wiring and grounding incorrectly or modifying the cover may damage the
equipment or cause injury.

WARNING
Sudden Movement Hazard. Set the MFDI parameters before you close control circuit switches. Incorrect Run/
Stop circuit sequence settings can cause serious injury or death from moving equipment.
WARNING
Sudden Movement Hazard. Correctly wire the start/stop and safety circuits before you energize the drive. If you
momentarily close a digital input terminal, it can start a drive that is programmed for 3-Wire control and cause serious injury or death
from moving equipment.
