Operating Procedures 4.3 – General Correct operation of the TI47UH1-46AH MPU-24 includes both pre-use and operational checks of the unit. Knowledge of the operating limits, restrictions, performance, unit capabilities and functions is fundamental to correct and safe operation. The operator shall ensure compliance with the instructions in this manual that affect operational safety and the warranty of the unit.
Operating any electrical equipment in the presence of moisture creates possible horizontal. WARNING safety hazards and/or potential for equipment damage. Every effort has been TI47UH1-46AH MPU-24 made, within the scope of existing technology to prevent foreseeable safety hazards and make theunit moisture resistant to prevent damage or failure.
Unit inlet and outlet vent ports shall be covered from exposure. Unit shall be kept horizontal. It is recommended that the Tesla™ Protective Rain Cover be fi tted onto the unit to guard it from moisture (see Section 8). The limits...

4.11 – Regulated AC Power Plugging in with AC Power When the TI47UH1-46AH MPU-24 is plugged into ac power, the output is 28.5 volts. This voltage allows the system to recondition and recharge the aircraft’s battery(ies). It is also an optimum voltage for powering avionics and lighting on most aircraft.
Section 5 – Post Operations 5.1 – General When not in use, the TI47UH1-46AH MPU-24 should be stored indoors guarded from moisture and extreme temperatures. To extend cell life, the unit should be plugged into ac power source. Although the unit has been made weather resistant within the scope of the unit’s intended use, it is essential that good general...

CAUTION Guard From Incorrect Power Source The TI47UH1-46AH MPU-24’s power cells may be damaged if recharged by NiCad or Lead Acid-type battery chargers. Power cells should only be charged by either the TI47UH1-46AH MPU-24’s internal charger and the ac power cord furnished with the equipment, or when connected to aircraft’s external dc power receptacle.
Avoid Prolonged Exposure to Extremely Damp Environments Be sure to disconnect ac power from the ac source if the TI47UH1-46AH MPU-24 has come into contact with water. If the AC Input Circuit Breaker has tripped due to water infiltration, allow the unit to dry out before attempting to reset circuit breaker.

5. Will a Tesla™ Turbo Start™ spool up a turbine engine? Nothing will start a turbine engine faster or safer than the right Tesla™ Turbo Start™. Not only will it eliminate hot starts, but it will extend the life of your starter, your engine and your battery while reducing maintenance. The Turbo Start™ senses the impedance from the starter/generator.
Unit should never be allowed to discharge fully. In-fi eld use, it receives a dc back charge directly from a running engine. When not in use, unit should be plugged into ac power (outlet) all the time. Tesla™ systems will retain 80% of their capacity after one year of storage.
