• When using the remote reset, connect the remote reset input terminal to the (GND) common terminal for
at least 10 ms.
Before inputting the remote reset a second time, set the unit to OFF for at least 70 ms.
• Use SN75451or SN75452 for an electronic switch.

The common pin should be wired separately from the shield sheath.
(Prepare a proper switch and a shielded cable by yourself.)
