Mounting and Cooling

for the enclosed micro drive mp, four mounting holes (m3) are provided to attach the unit to your application securely it is crucial to use the appropriate tightening torque suitable for the fastener and the type of mounting material being used while the micro drive mp is primarily intended for aerial vehicles, it is worth noting that implementing vibration isolation for the unit, especially in land based applications, will significantly enhance its durability over time it is essential to incorporate adequate mechanical strain relief for all cables connected to the unit this ensures appropriate support and protection against any undue stress or tension on the wires the current sensing accuracy on the micro drive mp is sensitive to external magnetic fields with this in mind, its important to not mount the mp directly to a ferrous material like steel within approximately 30mm \[1 2 in] of strong external magnetic fields doing any of the above will affect current sensing accuracy and may impede over current protection systems if any of these are unavoidable in your case, please consult the hargrave technologies team for assistance and advice cooling considerations the micro drive mp is supplied with a built in housing that effectively meets the thermal management needs of the device to fully utilise the 120a phase current rating in this setup, it is necessary to ensure a minimum airflow of 12 m/s \[39 4 ft/s] parallel to the heatsink (for a 25°c \[77°f] ambient air temperature)
