SECTION 2 PRE-INSTALLATION CONSIDERATIONS
2.1 COOLING
The TI250 Series does not require external cooling or contain internal active cooling. Cooling of the
unit occurs exclusively through passive conduction through the base or radiated cooling across the
metal case. Additional cooling can be realized through convective effects of the environment
(exposure to free moving air). These methods are not required to achieve rated performance but
can help prevent potential overheating and extend life when the unit is operated at full power or
during overload conditions. Specifically, mounting the unit to a metal surface is preferred, but not
required.
2.2 EQUIPMENT LOCATION
The TI250 Series 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.
However, 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 TI250 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.
2) 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.
