IMPORTANT
The On-Machine Drive has multiple grounding locations. Refer to the
electrical schematics for specific information about the grounding for your
specific configuration. See the
Catalog Number Explanation on page 16
more information about configuration type.
The safety ground, PE, must be connected to earth-grounding-system.
Some codes may require redundant ground paths and periodic examination
of connection integrity.
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
OFF position when the unit arrives. Verify that all breakers are OFF before
startup is initiated. For more information, see
section.
