Power Requirements
This section provides information regarding array 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 specifications for these units. Refer to Table 4-6 and Table 4-7
for more information.
