5 Installation Procedure◆ Section Safety
DANGER
Electrical Shock Hazard
Disconnect all power to the drive, before servicing.
Failure to comply will result in death or serious injury.
Wait at least one minute after all indicators are off. The drive
has internal capacitors that remain charged even after mainpower supply is disconnected. The drive charge LED will
extinguish when the DC bus voltage is below 50 Vdc. Measuredrive DC bus voltage to confirm safe level.

NOTICE
Damage to Equipment
Properly connect the connectors.
Failure to comply may prevent proper operation and possibly
damage equipment.
