3.1.3 Mating Cable Guidelines
The mating cable connects the Iridium Edge to external power and external controller with RS232 and
optional control inputs. The below lists the conductor gauge recommendations based on the external
cable length.

CAUTION Use only qualified cables with a IP67 connector provided by
your Service Provider with the Iridium Edge connectors. Failure to do so
would create an improper seal, allowing moisture and water vapor to enter
the device which in turn could lead to corrosion and damage to the device.
This could cause the device to fail, and could result in injury or damage.
3.1.4 Load Dump Protection
The Iridium Edge is designed to operate through voltage transients as per SAE J1455 and survive input
large load voltages. The Iridium Edge survives large load dumps by internally disconnecting the input
voltage when large voltages are detected. Once the input voltage is restored to a valid operational input,
the Iridium Edge resets the SBD modem and resumes operation.
