ing and prevents electrical fires. The power wiring should be connected
directly to the battery when possible for optimum noise immunity.
Electrical power
requirements
The 961 is a negative-ground system. After the processor has been
installed—but before you turn the 961 on—verify that the wires in the
10-foot power cable are connected as follows:
• Red — positive (+) 10 to 40 Volts DC (VDC)
• Black — negative (–)
Wiring the
system
The back of the processor, with all the proper wiring and connections, is
shown in “Figure 4: Processor connectors (back of unit)” below.

CAUTION!
Ensure that fuse or circuit-breaker protection is provided at the
power source. If you must cut the processor’s 10-foot power
cable shorter, be sure to keep the external fuse intact. If the
power cable must be longer than 10 feet, use a heavier gauge
wire for those applications, and be sure to use an external fuse.
