Note
Notes on operating under marginal conditions
When looping through the power supply, take into account the limit values; in other words, the
maximum permitted current depending on the ambient temperature; refer to the table
"Operation under marginal conditions" below.
When looping through the power supply under the marginal conditions described below, the
device may only be operated if it is installed horizontally. Horizontal installation position means
that the device is mounted, for example on a horizontal DIN or standard rail or that the labeling
on the device can be read in the normal reading direction.
If no power is looped through, any installation position is permitted.
