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, 15 Ampere
The ATC 15 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.
OR
Cause the ATC 15 Ampere DC OUTPUT FUSE to open circuit while a Battery Saver
connected load in excess of 15 Amperes is being supplied by the vehicle battery with
the Battery Saver OFF.
Example:
A load of 13.5 Amperes will cause the Batery Saver Power Supply to limit output current to
10 Amperes with a corresponding decrease of output terminal voltage to less than 10.0
VDC. This same 13.5 Ampere load WILL NOT cause the ATC 15 Amp fuse to fail when the
load is connected to vehicle battery via the 091-92-12.
Manage Battery Saver Connected Loads to 10 Amperes or less!
