The recommended use of the remote on-off is:
a) A switch wired between the L-H pins (On-level impedance
between L-H pins: <500kΩ)
b) A switch wired between (input/starter) battery plus and H-pin
(on level: >3V)
c) Connection between "VE.BMS charge disconnect" and H-pin
d) A switch between the L-pin and (input/starter) ground (on level:
<5V)
Note: Voltage tolerance L & H pin: +/- 70V
