Recommended Operation - Iridium EDGE User Manual

3.3.1

Recommended Operation

It is recommended that the On/Off control line, if used, is switched to ground to power down the Iridium
Edge. A switch to ground circuit, rather than a switch to power circuit, is recommended as this circuit
avoids exposing the On/Off input to power supply transients. Although the On/Off accepts the maximum
input supply voltage, the On/Off input does not have load dump and transient protection like the supply
input. In no case should the On/Off input exceed the absolute maximum voltage ratings.
