Remove the Power Module from the Enclosure
Follow these steps to remove the power module from the enclosure.
1. Review the Product Advisories on page 14
.
2. Remove power from the system. See Remove Power from the System on
page 15
.
3. Open the corresponding power bay enclosure door.
4. If a DC link fuse assembly is installed, remove the upper guard from the

IMPORTANT The service ramp is used only with power module when the cabinet is
mounted directly to the floor. Do not use the ramp to remove LCL filter modules
from the cabinet. Review service ramp instructions before using.
ATTENTION: IGBT power and LCL filter modules have a high center of gravity
and a tip-over hazard exists. To guard against death, serious personal injury, or
equipment damage, do not subject the module to high rates of acceleration or
deceleration while transporting. Do not push or pull above the points that are
indicated on the module.
