Ensure that fuse or circuit-breaker protection is provided at the
power source. If you must shorten the 10-foot power cable, 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.
The 961/962 is a negative-ground system. After the processor has been
installed—but before turning the system on—verify that the power cable
wires are connected as follows:
•
Red — positive (+) 10 to 40 Volts DC (VDC)
•
Black — negative (–)
The back of the processor, with all the proper wiring and connections, is
illustrated in "Figure 4: Processor connectors (back of 961/962)" below.
