SECTION 2
PRE-INSTALLATION CONSIDERATIONS
2.1
COOLING
No external cooling is required. The unit is equipped with two internal DC fans. Restriction to airflow can
cause overheating of the unit and limit performance or reduce the expected life of the product. Make sure
to provide adequate clearance on both ends of the unit with the hexagonal openings to allow for proper
circulation. In general, four to six inches of clearance on both ends of the unit should be acceptable.
Mounting the unit to a metal surface can also help reduce the effects of temperature within the unit but is
not required.
2.2
EQUIPMENT LOCATION
The TI1200 Series Static Inverter is designed for mounting flexibility, allowing for installation inside or
outside the pressure vessel with no requirement for temperature control. In addition to altitude and
temperature resistance, the unit is also designed to withstand high levels of condensing humidity.
Installation locations where the unit could be subject to standing or direct water exposure should be
avoided. The unit can be mounted in any orientation. Clearance should be provided for the mating
connector and may require as much as five inches past the unit connector to allow for back shell access
to the connector.
2.3
ROUTING OF CABLES
The wires and cable bundle associated with the unit are heavy gauge wire and carry significant power. Be
aware of routing cables near other electronics or with other wire bundles that may be susceptible to high
energy flow.
Avoid sharp bends in cabling and routing near aircraft control cables. Also avoid proximity and contact
with aircraft structures, avionics equipment, or other obstructions that could chafe wires during flight and
cause undesirable effects.
2.4
LIMITATIONS
The TI1200 Series of static electric power inverters is certified to FAA TSO-C73 with the following
limitations identified:
1) Alternating current (AC) output is provided at 115 volts and 60 Hertz in lieu of 115 volts and 400
Hertz as identified in the MPS of the TSO. This applies to the TI1200 models. Performance
complies fully with all tests and requirements of the MPS of the TSO accordingly.
2) Alternating current (AC) output is provided at 230 volts and 50 Hertz in lieu of 115 volts and 400
Hertz as identified in the MPS of the TSO. This applies to the TI1202 models.
3) Equivalent environmental qualification was verified per RTCA DO-160G in lieu of those identified
within the MPS of the TSO.
The conditions and tests for TSO approval of this article are minimum performance standards. Those
installing this article, on or in a specific type or class of aircraft, must determine that the aircraft installation
conditions are within the TSO standards, specification of the article, and deviations as listed above. TSO
articles must have separate approval for installation in an aircraft. The article may be installed only
according to 14 CFR part 43 or the applicable airworthiness requirements.
