INTRODUCTION
The Auto Charge T, Model 091-80-xx battery charger is a compact completely automatic
charger designed for installation in systems which require a transient suppressed char-
ger. Ideal for electric utility applications to maintain the batteries used in high voltage
circuit breaker trip circuits or wherever the charger may be exposed to high electromag-
netic elds. Red, yellow and green indicators are provided to indicate whether the
battery is fully charged, charging normally or receiving the maximum current.
Construction of the Auto Charge T is extremely rugged to withstand shock and vibration.
In addition the line power input lines and the charger output terminals are provided
with lters and MOV transient suppressors. These suppression circuits permit the char-
ger to meet ANSI/IEEE C37.90.1-1989.
INSTALLATION
The Auto Charge T Automatic Battery Charger should be installed in an area with
adequate ventilation. A power cord is supplied for connection to 115 volts 60 Hz.
1. Mount the charger using the four holes provided for this.
2. Connect the wiring from the battery to the Output Terminal Strip. Spade lugs that
have been securely crimped, or soldered, should be used.
3. Double check all wiring before proceeding.
4. Wire the A.C. power line cord to 115 volts.
