10. Remove the two mounting bolts at the back top of the module. Then remove the four
mounting bolts at the front bottom of the module. If this is a frame R8 module, the
cabinet framing set screw must be loosened so the retaining bar can be raised to
clear the output bus bars.
11. Remove the lower mounting bracket from its position after the four screws are
removed. The module is now free and may be removed from the cabinet. The
module is on a roller rack frame in the cabinet.
Recommendation
Be very careful removing the module. Frame R7 modules weigh 200 lbs and frame
R8 modules weigh 450 lbs. Both are top heavy.
The module may be slid onto a forklift and should be secured before moving.
12. With the removed module in a secure position, remove the bus bar fuse stubs from
the top of the module and install them on the replacement module before installing
the new module in the ACS800-PC cabinet.
13. Install the new module in the reverse order of removal. Secure the module to the
cabinet before beginning power and control connections. Torque and check all
connections before applying power.
