What it is and where it sits on the BOM
The ABB ACS510-01-088A-4 is an inverter drive built around the ACS510-01 series, listed as a wall-mounted unit sized for 380 - 480 V supplies at 50 - 60 Hz — so it drops straight into a standard three-phase industrial cabinet on a global mains voltage without an upstream transformer. Mounted on the wall rather than a DIN rail, with a 45cm x 27cm x 60cm envelope, it carries a 26.5 Kg handling mass and a 28 Kg shipping weight — the panel has to take that mass near the gland plate, and the cabinet layout has to leave derating airspace above and below for the heatsink path.
What the input class really means at the lugs
For the wireman this is the bracket that decides cable sizing and breaker selection upstream — anything outside that band means a step-down transformer or a different drive family, not a parameter tweak.
Sourcing reality
With an estimated 6 - 10 week lead time on the order code, the ACS510-01-088A-4 is a quoted-to-order line — it gets specified into the BOM and pulled through procurement against an RFQ rather than pulled off the shelf.
Panel-side handling notes
Wall-mounting with a 26.5 Kg drive mass means the fixings into the cabinet back-plate have to be rated for sustained vibration load, not just static — pair the lift with a second pair of hands or a panel jack, because the 28 Kg shipping weight is what the freight handler sees, not what the installer feels when the unit is cantilevered onto the upper mounting screws. Keep the cable entry path short and shield-ground at the panel end only on any signal cable leaving the drive — the same loop-discipline that keeps common-mode noise out of the analog runs elsewhere on the machine.
