What this order code is
The ABB ACS800-U1-0100-5+L503+N683+P901 is a wall-mount single-drive ACS800-U1 build, factory-configured with plus-code options L503, N683 and P901, on the Motor Drives line. The plus-code tail — L503, N683 and P901 — is part of the order string itself; when this BOM line was frozen, the three options were specified together and the drive should be quoted with that exact suffix to avoid a parametric mismatch on delivery.
Handling and mounting envelope
Listed at 65.77 kgs, the unit is a two-person lift and needs the wall-mounting kit the ACS800-U1 frame ships with — plan cabinet reinforcement and overhead clearance before it arrives, not after. Keep the gland-plate area clear for the power and motor cabling the ACS800-U1 footprint expects; for a retrofit, lay the new gland pattern over the existing cut-out before lifting the drive off the pallet.
Where this generation sits in the ABB drive lineup
The ACS800-U1 is the wall-mount form factor of the legacy ACS800 family; it sits below the current ACS880-01 platform and above the older ACS550-U1 generation on the same Motor Drives line. ACS580-01-180A-4 (listed at 54.43 kgs) and ACS550-U1-157A-4 (listed at 89.81 kgs) sit alongside on the Motor Drives line and are useful only as second-source deliberation context — neither is the same frame generation as the ACS800-U1 and neither is a confirmed cross-reference.
Sourcing posture
The factory order string with plus-codes L503, N683 and P901 is specified into the BOM as a single line; sourcing to that exact suffix against an RFQ keeps the configured drive and the panel's wiring diagram matched.
