7.4Description of Power/Control Terminals

WARNING

The Base Drive Panel might sustain serious or irreparable damage if connected incorrectly.

The power cables and/or busbars must be secured mechanically outside the converter in order to provide proper stress relief at the terminals.

Base Drive Panels are complete drive assemblies that include all semiconductor type fuses, main contactor, and a control transformer, ready to be connected and operated. All external connections to Base Drive Panels, including power connections are made with compression type terminals on the drive.

The user is responsible for installation of the motor, SIMOREG Base Drive Panel, transformer, and other devices in accordance with the National Electric Code and other applicable local codes that cover such items as wire size, protective grounding, disconnects, and short circuit protection. Depending on the rating, base drives can accommodate a range of cable sizes as indicated below.
