Power Requirements

This section provides information regarding drive module AC power requirements, power cord routing instructions, and site wiring conditions.

The AC power source must provide the correct voltage, current, and frequency specified on the manufacturer’s nameplate. Internal AC power units for rackmount cabinets must be able to handle the power requirements for these units. Refer to Table 3-7, Table 3-8, and Table 3-9 on page 3-9for more information.
