Orientation and temperature derating
The 6ES7 193-6BP20-0BB1/ 6ES7193-6BP20-0BB1: Operating temperature range depends on mounting orientation. Horizontally installed units are rated for -30 to 60 °C; vertical installation restricts the range to -30 to 50 °C. For panels with constrained airflow or vertical rail mounting, plan for the lower limit.
