longer than "HARDOFF" (Operating System gets frozen, etc), power will be
shut down hard, turning off all power rails. During the HARDOFF procedure,
the battery levels will be constantly monitored to prevent deep discharge
situations.
5) M4-ATX-HV will go to step 1, if ignition is tuned ON again.
NOTE. When all dip switches are off, M4-ATX-HV acts as a regular power supply.
M4-ATX-HV will also send a gratuitous "ON" pulse (to the ON/OFF motherboard
pins, should you have a wire harness connected to it) when power is applied for the
first time. Do not connect the on/off switch if you don't want your PC to be started
automatically.

When operating at <8V or >28V or extreme temperatures, de-rate by 30-50%, ventilation might be
required. When operating at constant 160watts or more forced ventilation is required.
