WIRING: BASIC CONFIGURATION
A basic wiring diagram is shown in Fig. 3, and described below. The diagram
shows the standard power and battery connections, as well as some basic uses
for the inputs and outputs.
Power Connection
The battery is connected to the module’s B+ pin though a fuse, a diode, and a
keyswitch. The fuse protects the wiring in the event of a short or failure. The
return path of the coils is also brought back to the B+ pin to utilize the flyback
diodes connected inside the module between B+ and each driver output.
The keyswitch is used to turn on the system. When the keyswitch is closed,
B+ goes high and the 1356 /1356P’s power supply brings up the module.
