3.3 MECHANICAL INSTALLATION

The power units must be properly secured in the drive cabinet, making it possible the easy withdrawal and
reinsertion in case of maintenance. The fastening must also be done so that it prevents panel transportation
damage.
The "panel mounting rack" accessory simplifies the mounting of the power units and allows their simple fastening
and movement. Refer to "Rack 2/Rack 3 Mounting Guide".
