1.1.1 Introduction
This manual provides general installation information for the CANplusTM CP750-E. This
manual’s target audience is professional installers for Engine Distributors and OEMs of engine-
driven machines. The engine manufacturer specific application information should be followed
for any detailed or specific requirements. Cattron sales and technical support are available at
www.cattron.com/contact to discuss specialized requirements or custom applications.

2 Mechanical Mounting
The CP750-E control panel is adaptable to a wide variety of applications. The included engine
harness connector facilitates quick installation.
The following is a list of installation guidelines:
1) The panel mount shall be
a) Easily accessible by the operator.
b) Placed away from moving equipment.
c) Stable during equipment operation and transportation.
2) The vibration isolation mounts shall
a) Be properly installed.
b) Have normal movement.
c) Be located so the panel does not hit any adjacent structure during operation.
2.1 AluFlex™ Panels
AluFlex panel enclosures are constructed from extruded aluminum and powder-coated for
durability. The faceplate is aluminum or powder-coated galvanized steel and the backplate is
powder-coated galvanized steel. The enclosure is splash proof and includes condensation
drain holes in the bottom.
AluFlex panel isolation mounts are preinstalled to a heavy-duty mounting bracket with
mounting holes to accommodate various installations. Isolator mounts should not be twisted
when installed, as doing so will lead to premature failure.
2.1.1 Mounting Templates
The following two figures (not to scale) show the one-to-one hole template for the CP750-E
mounting bracket.

4 Typical Wiring
The following subsections describe the typical engine interface wiring.
4.1 Power and Ground
The panel’s Power and Ground must connect directly to the battery posts and must not share
power and ground wiring with any other devices, especially any high current loads. The Power
line should have overcurrent protection in the form of current-limiting devices, fuses, circuit
breakers or fusible links to protect the harness wiring in the event of fault conditions.
4.2 ECU Power Out
The CP750-E can directly power the engine ECU.
4.3 Starter Power Out
The Starter Power Out is intended to power the starter relay, which is required. When power is
removed from the relay coil, the collapsing magnetic field generates a negative voltage surge.
Negative voltage surges can damage components. The CP750-E has protection against these
negative surges. However, it is still required to have a protection/suppression diode as close to
the relay as possible. Cattron recommends the use of relays that have this
protection/suppression diode built in. The protection/suppression diode must have sufficient
voltage ratings to survive and sufficiently suppress these negative voltage surges. Cattron
recommends a 1N4001 diode. Cattron sells a spike-suppressing diode kit (Part Number 630-
4007-77).
4.4 Resistive Senders
The Resistive Sender connections send system voltage out to the sender to obtain the current
value. It is required that the sender return connection be connected to a ground point (the
engine chassis, for example), as close to the sender as possible in order to get an accurate
measurement. If more than one sender is used, each sender should have a sender return
connected to a ground point near that particular sender. All sender returns should then be
connected together near the panel and the combined returns connected to the panel’s sender
return input.
4.5 CAN Bus Termination
CAN bus requires two 120 Ω termination resistors each at the extreme ends of the wiring
harness. Typically, the engine ECU provides the termination resistor on its end (see the engine
documentation to verify). The CP750-E has a termination resistor that can be turned off and on
as needed. The CP750-E’s default configuration has this termination resistor turned on.

5 Testing
WARNING
DURING THE FOLLOWING PROCEDURE, CORRECT ANY PROBLEMS BEFORE PROCEEDING
TO THE NEXT STEP. CONTINUED TESTING MAY DAMAGE THE PANEL, HARNESS OR ENGINE.
Use the following testing procedure:
1) Turning the keyswitch ON initiates self-test; check all connections and battery polarity on
failure.
2) Test to verify overcurrent protection; identify and correct any wiring fault on failure.
3) Verify fuel run/stop solenoid or ECM energizes.
4) When the key is turned on, the fuel solenoid should be powered for until the display times
out (configurable).
a) The ECM should send CAN bus data as soon as the self-test completes.
b) Verify engine cranks when the key is turned to start; check all connections on failure.
5) If the engine does not start, check the fuel lines and bleed if necessary.
6) Verify gauges and indicators with the engine running.
a) See the CP750-E User Manual for details.
7) Test all safety shutdowns.
a) See the CP750-E User Manual for details.
8) Run the engine for an extended time to identify any temperature or connection problems.
