Simultaneous Input Points and Installation Spacing
For Connector Terminals with 32 transistor inputs, the ambient operating temperature
places a limit on the maximum number of points that can be turned
ON simultaneously.
For example, if Connector Terminals are mounted in a direction other than the
following directions at an ambient operating temperature of 55°C with all the
32 input points turned ON simultaneously, the Connector Terminals must not
be mounted closely together.
