INSTALLATION INSTRUCTIONS
IMPORTANT: For proper operation of the CPU-95 system, voltage
and current supplied must be sufcient during all selected modes
of operation. FIGURE 5 provides these details regarding the DC pow-
er hookup:
1. CURRENT DRAW PER SYSTEM:
Formula varies depending on number of outputs used, en-
gine cycle and RPM, and use of the multi-strike feature.
2. MINIMUM WIRE GAUGE REQUIREMENTS:
CHART 1 OF FIGURE 5 gives the requirement vs. the length of
run between the power source and the CPU-95 Ignition Mod-
ule.
3. MULTIPLE ENGINE INSTALLATIONS:
Multiply current required per system by the number of en-
gines. Where more than one engine is powered from a com-
mon power source, see CHART 2 OF FIGURE 5 for the minimum
wire size required.
9.3 WIRING SEPARATION:
Power wiring and signal wiring (pickups and communications) must
be in separate conduits and conduit entries into the Ignition Mod-
ule to avoid undesired electrical interaction. All conduit entries are
sized for a ½"-14 NPT male conduit tting. Separate as follows:
RIGHT CONDUIT ENTRY Input power wires
CENTER CONDUIT ENTRY Magnetic pickups and Hall-effect pickup
LEFT CONDUIT ENTRY Control inputs, alarm outputs, serial communica-
tions and power feed to Display Module
9.4 RIGHT ENTRY:
Input power supply wires (16 AWG minimum) should enter the right
conduit entry and connect to the POWER (24 VDC + and GROUND −) ter-
minals of the terminal block. SEE FIGURE 10.
9.5 CENTER ENTRY:
Run a separate conduit to the center entry for the two (2) magnetic
pickup cable assemblies. These should terminate per description on
the cover label in the Ignition Module which is SEE FIGURE 10.
4-CYCLE ENGINE ONLY: The cable from the Hall-effect pickup must also
enter through the center hole and be connected as shown.
NOTE: Engines using posi-
tive ground DC accessories
or starter motors will require
a separate dedicated power
supply for the CPU-95. A
separate power supply is re-
quired because the CPU-95
system is a negative ground
system and the minus must
be grounded.
