INTRODUCTION
The 091-92-12 BATTERY SAVER is a power supply with a load power transfer function. Loads connected to the BATTERY SAVER are powered by the vehicle’s battery when the AC power to the 091-92-12 Battery Saver is OFF. When AC power is applied to the 091­92-12 Battery Saver special circuitry within the Battery Saver transfers the load(s) to a power supply internal to the 091-92-12 Battery Saver. The Battery Saver power supply then provides low ripple 12VDC System power to Battery Saver load(s). Installation of a 091­92-12 Battery Saver eliminates the power drain on a vehicle battery and or a battery under­charge ensuring all vehicle battery charger power is available to charge the battery. The 091-92-12 Battery Saver is unique in that there is no interruption of power supplied to the loads during power transfers. The feature makes the 091-92-12 Battery Saver ideal for MDT (Mobile Data Terminal) and or 12VDC vehicle computer systems that may "re-boot" during an input power interruption.
INSTALLATION
1. Mount the BATTERY SAVER in a convenient location with 4 screws in the mounting holes provided. Be certain that adequate ventilation is available and that the unit is not subject to weather damage.
2. Connect the 115VAC input power to the BATTERY SAVER through a 3-wire line cord as shown in INSTALLATION WIRING DIAGRAM, Figure 1.
3. The low voltage connections are made through the DC output connector as shown in INSTALLATION WIRING DIAGRAM, FIGURE 1.
1. Connect terminal 1 to the vehicle’s 12 volt battery (+).
2. Connect terminal 3 to the +12 volt electrical loads.
3. Connect terminal 4 to the vehicle ground or to the battery (-).
The installation is now complete. Loads connected to the Battery Saver will be powered from the vehicle battery when the AC power to the Battery Saver is OFF and from the Battery Saver power supply when the AC power is ON.

TEST and OPERATION
The 091-92-12 Battery Saver system interface panel contains two (2) Green LEDs as follows: Refer INSTALLATION WIRING DIAGRAM, Figure 1. "LOAD POWER" LED: Illuminates when power is being supplied to the load(s) regardless
of the source of the power (Vehicle Battery or Battery Saver).
"BATT SVR PWR" LED: Illuminates when Battery Saver is receiving AC power and the
power supply internal to the Battery Saver is ON and functioning.
Installation Test
1. Remove AC power from the 091-92-12 Battery Saver.
2. Verify "LOAD POWER" LED is illuminated and loads are being powered by vehicle battery (voltage at load is approximately equal to vehicle battery terminal voltage).
3. Apply AC power to 091-92-12 Battery Saver and verify:
1."LOAD POWER" LED remains illuminated
2. "BATT SVR PWR" LED illuminates approximately five (5) seconds after application of AC power to Battery Saver.
3. Load voltage is between 13.2VDC and 13.4VDC
Operation
The 091-92-12 Battery Saver contains special circuitry that eliminates power delivery "glitches" or interruptions during load power transfer(s) from:
*Vehicle Battery to Battery Saver: Five (5) second delay as Battery Saver power
supply stabilizes. Installation Test para. 3.2.
*Battery Saver to Vehicle Battery: No delay
The MINIMUM voltage at the load during any power transition is:
Vehicle Battery VDC - 1.3VDC for a MAXIMUM of 150 milli-seconds (.150 seconds).

INSTALLATION PRECAUTIONS
Refer Figure1, INSTALLATION WIRING DIAGRAM and Specifications & Outline
The 091-92-12 Battery Saver is AC Input AND DC Output over-current protected as follows: 115VAC 60Hz Input: 5 Ampere DC Output: ATC, 10 Ampere The ATC 10 Ampere DC OUTPUT FUSE internal to the Battery Saver is common to both the Battery Saver Power Supply output AND the vehicle battery connection that supplies power to the load when the Battery Saver is OFF (115VAC to Battery Saver - OFF). Current OVERLOADING the Battery Saver in excess of 10 Amperes will:
Initiate current limiting of the Battery Saver Power Supply with a corresponding reduction of the Battery Saver Power Supply terminal voltage when the Battery Saver is ON until the DC OUTPUT FUSE open circuits.
OR
Cause the ATC 10 Ampere DC OUTPUT FUSE to open circuit while a Battery Saver connected load in excess of 10 Amperes is being supplied by the vehicle battery with the Battery Saver OFF.
Manage Battery Saver Connected Loads to 10 Amperes or less!
