IMPORTANT
This lock out / tag out is only for upstream power. During initial installation,
the On-Machine™ Drive does not have power. The breakers should be in the

ATTENTION:
Failure to observe this warning can result in machine damage
or personnel injury. Remove power from the drive system and wait for the
voltage on the bus to discharge before removing the cover or performing any
work on the drive.
SHOCK HAZARD:
The drive contains high voltage that takes time to discharge
after removal of the main supply. Before working on the drive, isolate the main
power supply from line inputs (L1, L2, L3). Wait 3 minutes for the system to
discharge to minimal voltage levels. Failure to do so may result in personal
injury or death.
