Drive Ratings and Panel Fit
The ACS355-03E-04A1-4: Housed in the R1 IP20 frame, this drive occupies the smallest footprint in the ACS355 family — suited for tight control panels where space is at a premium. Typical heat dissipation is 43 W under rated load.
Frame R1 accepts DIN-rail or screw-panel mounting; plan for incoming/outgoing cable clearance as per the user manual (not duplicated here). The drive supports a DC input range of 250–840 V with an MPPT window of 460–800 V, making it usable in solar-pump or common-DC-bus architectures — confirm the DC supply polarity and protection ahead of installation. IP20 enclosure requires installation in a clean, dry cabinet; no washdown or dust tolerance.
Kit Completeness and Physicals
For a full kit count, verify that your order includes the matching control panel (e.g., ACS‑CC‑x) if local HMI is required — the drive ships without one.
