On the integrated power section, the spindle must only be used at "A1".
Current reduction
All technical data are valid for ambient temperatures up to max. 40_C. In the
depending on event of ambient temperatures > 40_C currents must be reduced linearly as for
the OI mains supply. At a maximum ambient temperature of 55_C: current
ambient
reduction to 60% of the 40_C value.

Current reduction
All the specified load currents are valid up to a site altitude of 1000m. For site
depending on site altitudes > 1000m, load currents must be reduced in accordance with the OI
mains supply chart.
