*MaxFit13E, MaxFit33E, MaxFit35E, MaxFit37E, MaxFit55E, MaxFit75E and MaxFit77E:
The DC output for these power supplies are not power-limited (except for AL400ULXB2s in MaxFit13E). If a power-
limited output is required in the end-product application, the DC output from the power supply must be connected
to a separately Listed control unit or accessory board that provides power-limited outputs. The product(s) providing
the power-limited output(s) must be listed as appropriate for the particular end-product application and wired in
accordance with the products installation instructions. Class 1 wiring methods, separation of circuits, and proper
fire-rated enclosures all must be considered when connecting the DC output of the power supply to the end-
product devices. The auxiliary outputs of these units are power-limited.
