WARNING
HIGH VOLTAGE
Drives contain high voltage when connected to AC mains
input, DC supply, or load sharing. Failure to perform
installation, start-up, and maintenance by qualified
personnel can result in death or serious injury.
•
Only qualified personnel must perform instal-
lation, start-up, and maintenance.
•
Before performing any service or repair work,
use an appropriate voltage measuring device to
make sure that there is no remaining voltage on
the drive.
