Reverse Voltage Protection
The SonarMite is protected from reverse connection or direct short circuit by an
internal 1.0Amp thermal fuse. If the fuse is tripped then the system will need to be
disconnected for 1 minute for the fuse to cool down and reset itself.
Weatherproofing
The SonarMite has been designed to conform to the IP67 waterproofing standard, this
benchmark describes equipment which can withstand a light spray of water from a
hose for a short period of time, it does not imply the device is suitable for immersion
in any depth of water or exposed to prolonged harsh weather conditions. The
weatherproofing also assumes the connectors or cover caps are fully screwed on to
their rubber sealing rings. The weatherproofing does not apply to certain components
which are by definition not designed for outdoor use such as the mains battery charger
and D9 serial cable connectors.
