7.1 Section Safety
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 five minutes after all
indicators are off and measure the DC bus voltage level to confirm safe
level.
Do not allow unqualified personnel to perform work on the drive.
Failure to comply could result in death or serious injury.
Installation, maintenance, inspection and servicing must be performed only
by authorized personnel familiar with installation, adjustment and
maintenance of AC drives.
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.
