723PLUS Digital Marine Control
This chapter contains general installation instructions for the 723PLUS control.
Power requirements, environmental precautions, and location considerations are
included to help you determine the best location for the control. Additional
information includes unpacking instructions, electrical connections, and
installation checkout procedures.
Before handling the control, read the Electrostatic Discharge Awareness
information on page iv. Be careful when unpacking the electronic control. Check
the control for signs of damage such as bent panels, scratches, and loose or
broken parts. If any damage is found, immediately notify the shipper.
The low voltage version of the 723PLUS Digital Marine Control requires a voltage
source of 18 to 40 Vdc.
To prevent damage to the control, do not exceed the input voltage
range.
If a battery is used for operating power, an alternator or other
battery-charging device is necessary to maintain a stable supply
voltage.
To prevent damage to the control, make sure that the alternator or
other battery-charging device is turned off or disconnected before
disconnecting the battery from the control.

Location Considerations

Consider these requirements when selecting the mounting location:

adequate ventilation for cooling;

space for servicing and repair;

protection from direct exposure to water or to a condensation-prone
environment;

protection from high-voltage or high-current devices, or devices which
produce electromagnetic interference;

avoidance of vibration;

selection of a location that will provide an operating temperature range of
–40 to +70 C (–40 to +158 F).
The control must NOT be mounted on the engine.
