Installation Supplement for ACS550-U2 Drives
Installation
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.
