2.7.1 Shutdown Delay
Purpose:
The device starts up when the vehicle ignites and shuts down after the vehicle is off. The
vehicle ignition startup and shutdown are realized by the vehicle positive pole ignition switch
(providing high level signal when the switch closes). The wire connection of the device varies
with the vehicle ignition models.
Ignition switch is connected to the positive pole of +12/24 VDC of vehicle batteries. Make
sure that the connection is correct, and then perform the following steps:
Step 1 Connect the "DC IN +" of the device to the positive pole of vehicle batteries, jumping
over the switch of normal vehicle power.
Step 2 Connect the "DC IN -" of the device to the negative pole of vehicle batteries.
Step 3 Connect the "ACC" of the device to the vehicle ignition switch.
