Figure 3.4F: Dual 400 Hz Synced Installation
Note: The AC outputs are not designed to be connected in parallel with other units
regardless of the optional phase sync function.
Example Wiring Diagrams
The inverter is flexible in the wiring installation allowing for it to be integrated into the
aircraft according to the application needs. Several examples are shown in the diagrams.
Harness Verification
With the TI250 Series Static Inverter disconnected, activate the aircraft power bus that
supplies the unit and use a multi-meter to verify that aircraft power and ground with
appropriate voltage is on the pins within the mating harness.
3.4 MOUNTING
Refer to Section 2: Pre-Installation Considerations in regards to equipment location.
The TI250 Series Static Inverter is designed for base mounting only. Four #10 mounting holes
should be provided in the aircraft in accordance with Figure 3.5. Secure the unit with four #10 pan
head Phillips screws, or equivalent. A lock washer under the head of each screw is recommended.
3.5 INSTALLATION COMPLETION
Prior to operating the unit in the aircraft, it is recommended to verify the output and functionality of
the unit. In order to prevent accidental damage to other systems, it is best not to attach the output
to other equipment or power busses prior to verification. Verify the output of the unit at the
terminating end of the cable with a multi-meter to ensure proper voltage and polarity. Once
verified, installation can be completed and functionality of the remote on/off feature (if used) should
be checked.
