Why the +J429 suffix matters on the order code
The trailing +J429 is an ABB option-code suffix — it changes what ships from the factory versus what gets wired up later in the panel. Specifying the ACS580-01-065A-4+J429 by full order code is the only way to get that option built into the drive at the ABB build stage; substituting a bare ACS580-01-065A-4 and adding the option in the field is not the same part, even though the base drive rating is identical. For a BOM line that already names the +J429 suffix, the buyer is buying a configured drive, not a configurable one.
Panel-side fit and handling
At 19.05 kg the drive fits a single-technician cabinet lift. The heat sink path is front-to-back, so keep the rear of the enclosure clear of cable duct to preserve the cooling channel called out in the ACS580-01 installation guide.
