2.2. Installation
Instructions
NOTES & WARNINGS
Do not install near high-voltage or high-current devices.
Ground the chassis for safety purposes and proper EMI shielding.
Note the operating temperature range. All field wiring must be suitable for that temperature
range.
Install the unit with appropriate space available for servicing and for adequate wire harness
access (15 cm) and strain relief (30 cm).
Do not connect or disconnect the unit while the circuit is live, unless the area is known to be
non-hazardous.
MOUNTING
The module is designed for mounting on the engine. If it is mounted without an enclosure, the
Thermocouple Scanner should be mounted horizontally with connectors facing left or right, or with
the connectors facing down, to reduce likelihood of moisture entry.
The thermocouple wires and CAN communication cable are considered intrinsically safe. The
power wires are not considered intrinsically safe.
Mask all labels if the unit is to be repainted, so label information remains visible.
Mounting legs include holes sized for M6 or ¼ inch bolts. The bolt length will be determined by the
end-user’s mounting plate thickness. Typically 20 mm (3/4 inch) is adequate.
If the module is mounted off-engine, no wire or cable in the harness should exceed 30 meters in
length. The power input wiring should be limited to 10 meters.
CONNECTIONS
Use the following Deutsch IPD mating plugs to connect to the integral receptacles. Wiring to these
mating plugs must be in accordance with all applicable local codes. Suitable field wiring for the
rated voltage and current must be used. The rating of the connecting cables must be at least
85°C. For ambient temperatures below –10°C and above +70°C, use field wiring suitable for both
minimum and maximum ambient temperature.
