2.3 Installation
ION is intended for DZUS mount (or similar) installations. If you are unsure of the installation location,
please contact Churchill Navigation.
To ensure adequate airflow to the unit, Churchill Navigation recommends a minimum of 100mm
between the back of the ION and any adjacent surface.
The minimum ION installation requires 28VDC power and at least one type of supported video input.
Additionally, some operators may wish to include audio-in as a part of their basic setup. The
corresponding Installation Manual sections required for minimum operation as described above are:
1) Power – Sections 2.3.1, 2.3.2, and 2.3.3.1
2) Video – Section 2.3.3.5 (HD-SDI) and Section 2.3.3.6 (Analog)
3) Optional audio-in – Section 2.3.3.3
Support for these as well as all other inputs and features are described in detail in the following sections
of this guide.
2.3.1 Voltage Requirements
ION operates on 28-volt DC power and consumes a maximum of 112 watts (4 amps on 28VDC).
Churchill Navigation recommends using a minimum 7.5-amp circuit breaker.
2.3.2 Ground Requirements
ION IS CASE-GROUNDED THROUGH THE DZUS MOUNT. If the DZUS mount is not directly grounded
to the chassis, use a minimum of 16-gauge wire to ground the DZUS mount prior to ION operation.
EXPOSED ALUMINUM IS CHROMATED. DO NOT CHEMICALLY COAT OR COVER WITH NON-
CONDUCTIVE MATERIAL.
ALL GROUND PINS EXCEPT 28V RETURN ARE GROUND CONTINUOUS TO CASE.
Failure to properly ground the ION unit may result in damage to the ION as well
as possibly other installed equipment.
2.3.3 Cabling requirements
To ensure a properly functioning ION, the following cabling requirements are highly recommended.
Any variation will be at the sole responsibility of the dealer or installer. Detailed installation
diagrams are provided in Section 3 of this manual.
Install each cable with an 8 inch [203 mm] service loop to allow for easy servicing of the
ION unit.
