CHAPTER 2 UNIT DESCRIPTION AND OPERATION SECTION I. UNIT 2-1. GENERAL The TI4676 (Figure 2-1) is a compact, portable and highly versatile 24/ 28.5 VDC electrical MPU. The unit incorporates a 120-240 50/60 Hz to 28.5 VDC converter, a 24 volt unique (dry) power cell and an internal intelligent 120-240 50/60 Hz VAC charger to recharge the power cells.
WARNING Check fuse holder window to ensure the fuse setting reads either 120 or 240 prior to connecting recharge cord to AC power source. Fuse setting (120/240) must match AC power source (hangar wall, flight line AC power) prior to connecting MPU for recharging.

3-8. CONTINUOUS OUTPUT RATE, 28.5 VDC CONSTANT OUTPUT 35 Amps at 1 hour (with AC power connected) NOTE If current demand exceeds 12 amps, converter output voltage will drop below 28.
CAUTION Unit may be damaged if operated when unit’s cold or heat soaked tem- perature exceed the specified limit. If unit is operated when cold or heat soaked temperature limit is exceeded; a full functional check should be accomplished prior to continued use.
WARNING ********SHOCK HAZARD POTENTIAL********* Severe injury, or Death, from electrical shock is possible when person- nel and/or TI4676 are wet during use and when 120-240 50/60 Hz VAC power is being supplied to unit.
CAUTION Unit damage may occur if inlet and outlet vent ports are obstructed and/or cooling airflow is restricted. Back Vent Side Vents Cooling Fan 3-13. UNIT OPERATION DURING AIRCRAFT FUELING/DEFUELING Power output is restricted to 24 VDC power cell output only.
CHAPTER 4 OPERATING AND INSTALLATION PROCEDURES SECTION I. UNIT INST ALLA TION 4-1. INSTALLATION 1. Remove original aircraft battery and dispose of properly (follow your aircraft’s manual for proper removal and disposal of aircraft battery). 2. Ensure that the TI4676 MPU is fully charged.
SECTION II. OPERA TING PROCEDURES (cont.) 4-5. OPERATING PROCEDURES This section deals with normal procedures, and includes all steps nec- essary to ensure safe and efficient operation of the TI4676.
CAUTION REMEMBER, when the AC line cord is plugged in, the unit must be placed in a position to allow the cooling fan to operate properly! Unit may overheat if cooling fan fails.
CAUTION Unit may overheat if cooling fan fails. Do not operate if cooling fan fails. 2. CHECK FOR FULL CHARGE INDICATION - After 1 HR 15 minutes, LED charge indicator should show a single steady or flickering LED bar when fully charged. AC power may be left connected to unit when power cells are fully charged.
SECTION III. FUNCTIONAL CHECK PROCEDURES AND TROUBLE SHOOTING 4-8. FUNCTIONAL CHECK PROCEDURES This section deals with normal functional check procedures, and includes all steps necessary to ensure the TI4676 is functioning within specific operational parameters prior to operational use.
7. CHECK DC VOLTAGE READING AT DC RECEPTACLE TERMINALS. Ensure power cells are fully charged (see step 6.) 28.5 (±0.57 VDC) with power cells at full state of charge. 8. FUNCTIONAL CHECK COMPLETE - Unit should remain plugged in to AC power until ready for installtion in aircraft.
