Mounting
Fastening the Unit
See the "Dimensional Drawings" in the "Technical Data" section of this document for
the exact locations of the mounting points.
1. Use at least four screws – two at the front, two at the back – to attach the unit base
plate to the floor.
2. Use at least two screws to attach the back of the enclosure to a wall.
There are two holes available at the top of each: the extension module and the drive
module.
Connecting Power and Control Cables
Additional considerations that apply with the enclosure extension:
• The power cable connection diagram that applies for the ACS550-U2 is:
• Temporarily remove the upper high voltage shield (clear plastic) to gain access to
the power connections in the extension module.
• To avoid metal shavings inside the cabinet, temporarily remove the gland/conduit
plate at the top of the extension module. Then drill holes and mount conduit or
cable fittings as needed.
