<Reference>
Use a safety relay unit or an equivalent control circuit in safety for FSD.
Connect the shield to the frame ground (F.G.) without fail. Failure to do so can
cause malfunction due to noise, which can result in serious injury or death.
Further, the wiring should be done in a metal box connected to the frame ground.
Take countermeasure against the system to be applied for this device so as not
to carry out the dangerous performance caused by the earth failure. Failure to do
so could cause invalid for the system stop, resulting in serious body injury or
death.
