DANGER
Electrical Shock Hazard
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 at least one minute after all indicators are OFF and measure the DC bus voltage level to confirm safe
level.
WARNING
Do not operate equipment with covers removed.
Failure to comply could result in death or serious injury.
Do not perform work on the drive while wearing loose clothing, jewelry or without eye protection.
Failure to comply could result in death or serious injury.
Remove all metal objects such as watches and rings, secure loose clothing and wear eye protection before beginning
work on the drive.
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
Do not allow unqualified personnel to use equipment.
Failure to comply could result in death or serious injury.
Maintenance, inspection and replacement of parts must be performed only by authorized personnel familiar with
installation, adjustment and maintenance of AC drives.
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.
CAUTION
Crush Hazard
Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
NOTICE
Observe proper electrostatic discharge procedures (ESD) when handling the drive and circuit boards.
Failure to comply may result in ESD damage to the drive circuitry.
Check all the wiring to ensure that all connections are correct after installing the drive and connecting any other
devices.
Failure to comply could result in damage to the drive.
