4.4 Connection remote on-off

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) A switch between the L-pin and (input/starter) ground (on level:

<5V)

Note: Voltage tolerance L & H pin: +/- 70V

a) L-H pin wiring

b) H-pin wiring

c) L-pin wiring

4.5 Engine detection override

Applying >7V to the L-pin of the remote on/off circuit activates the

“engine detection override” function. The charger is on as long as

the “engine detection override” is active. With this function an

external control (e.g. ignition switch, CAN bus engine on detector)

can determine if charging is allowed.

The remote on/off function also needs to be activated so option a)

or b) in figure 3 must also be connected. See examples in figure 4

below.
