Units with Connectors
Note
262
The following ambient operating temperature restrictions apply when multiple
32-point Slave Units with MIL Connectors are mounted in parallel.
When Units Are Not Mounted Facing Upwards:
Units can be densely mounted (16 points can turn ON simultaneously at an
ambient operating temperature of 55 ° C).
When Units Are Mounted Facing Upwards:
If 16 points may be turned ON simultaneously, the distance between the Units
must be restricted depending on the ambient operating temperature, as
shown in the following graph. For example, when the ambient operating tem-
perature is 55 ° C, a space of at least 10 mm is required between Units.
