As shown in the table, "width" does not involve the dimensions of rack-mounting ears. The measurement point
of the temperature and humidity is 1.5 m (4.92 ft) over the floor and 0.4 m (1.31 ft) in front of the cabinet without
the front and back doors.
Short-term operation means that continuous operating time does not exceed 48 hours and accumulated operating
time per year does not exceed 15 days. If an operation exceeds either of these conditions, it is called a long-term
operation.
