MOUNTING
Refer to Section 2: Pre-Installation Considerations in regards to equipment location.
The TI1200 Series Static Inverter is designed for base mounting only. Four ¼-20 mounting holes should
be provided in the aircraft in accordance with Figure 3.5. Secure the unit with four ¼-20 pan head Phillips
screws, or equivalent. A lock-washer under the head of each screw is recommended.

INSTALLATION CAUTIONS
The TI1200 series is not protected against reverse polarity on the input 28VDC. Verify the voltage polarity on
the connector before connecting to the TI1200 for the first time.
The TI1200 series does not have the ability to phase sync the output to other AC power sources. Do not
connect the output of the TI1200 to any other inverter or AC source or damage to the TI1200 will result.
NOTE – Digital meters measure AC voltage with a very high impedance. As noted in section 3.3.7 the
TI1200 series has a balanced AC output that is not referenced to the chassis. If a digital meter is used to
measure the AC output to chassis, the reading will correspond to approximately ½ the inverter rated output
voltage. This reading may vary depending upon the presence of an optional noise capacitor (section 3.3.3),
permanently wired accessories, or presence of an external GFI. However, this voltage is not a problem and
is a result of using a high-impedance meter to measure AC voltages.

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 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.
